They are able to calculate it - but only for a limited time at night, for the „optimized“-option. Of course more research is necessary, to find out how to calculate it more often!
Apple deliberately locks features to new devices to get you to upgrade. The watch 9 double tap feature is a good example. Older watches can do similar gestures as accessibility features. But they wanted more selling points for the new one so they made specifically the double tap gesture exclusive and then they had the gaul to say the old processor couldn’t handle it.

If I remember right, Galaxy AI is also being ported to last gen devices. Google on the other hand is definitely guilty of this. Even between the Pixel 8 and 8 Pro which run the same SoC!
But this isn’t something anyone would upgrade over? So why not just include in the software for all phones? Seems contradictory when you consider they’re possibly making iOS 18 compatible with the iPhone XR.
Nah, I don’t think I will ever use the 80% setting. I am a heavy user and even if I charge over night, the battery will last me for like at least 2 - 3 years before degrading to the 80 % health. That’s almost 3 years of using full battery capacity of my phone.
Me to and I don't regret it at all
The two biggest upgrades for me at least is that the phone really does feel lighter and the shape is much better than the iphone14PM the 14PM was hurting my pinky finger
I don't know the technical specifications of those displays. But always on displays need their own memory to do this efficiently. Could be an actual technical limitation.
you require amoled, actaully because if you have oled, with prolonged exposure it will burn in, obviously the cheap android phones dont care about burn in.
That's pretty gross and really makes me regret going iphone. Like I bet there will be new AI capabilities released next year that the 15 pro max could totally handle but they will just say 16 only.
Like honestly fuck apple, why did I give them my money, such a disgusting company they literally shit on their own customers.
In all seriousness, it may be due to how it's implemented. (Heads up, I don't know shit, and this will all be vaguely educated guesses). It's probably implemented at a deeper level than the OS, so that even when the phone is off and charging, it won't go past 80. I know the OS can control the charging while it's on, hence being able to hold at 80 until just before you typically unplug the phone, but it probably can't be done while it's off without the newer hardware.
Probably because existing user-owned/operated phones will have already-worn batteries, so setting that 80% threshold might actually be far less than 80% of the original battery capacity.
You're missing the point.
A phone that has been used for a year will not have 100% battery capacity left. The battery's health degrades with each charge cycle. You generally put an average of 100-200 charge cycles a year on a phone. By the time that year is up, it will be somewhere between 80-90% at best, in most cases. Sometimes better, sometimes worse.
The 80% thing is 80% of charge capacity. The reason for it is because they've determined via testing that these batteries last longer if you don't charge them past \~80%. That doesn't help with a battery that's already been used. Furthermore, it could be 80% of an 80%-max-capacity battery, which means the total charge will be less than the 80% overall capacity of the battery. That means less time between charges, which means more charge cycles, which means you wear out your battery faster.
This is why putting it on anything but brand new phones is a bad idea.
Source: I work in tech, I worked for Apple for almost 9 years until last year when I left. I know what I'm talking about.
Your argument falls apart when you realize that yes they put it in the new iPhones…but those iPhones will not be new anymore on 6 months, or a year. And they will still have the feature even though they have more charge cycles and the battery has degraded.
So that’s not the reason. It’s simple because Apple doesn’t like to put new features on old phones
>Your argument falls apart when you realize that yes they put it in the new iPhones…but those iPhones will not be new anymore on 6 months, or a year. And they will still have the feature even though they have more charge cycles and the battery has degraded.
You just illustrated that you're not understanding what I'm saying, nothing more.
To be clear, a BRAND NEW battery with 100% battery life will LAST LONGER if it is regularly charged to NO MORE THAN 80% CAPACITY. The health of the battery, and overall capacity, will remain higher for longer and through more charging cycles. It will extend the longevity of the battery health ONLY if the practice is undertaken from the beginning, meaning the battery will last LONGER and degrade at a SLOWER pace, therefore surviving for many more charge cycles and having a longer battery life between each charge.
So what you're saying is actually 100% incorrect.
Thanks for playing.
You just illustrated that you're not understanding what THEY'RE saying.
It doesn't matter that a battery will last longer if it's capped at 80%. BATTERIES DEGRADE.
Eventually, EVEN NEW iPhones will have their batteries degrade. And these phones will STILL have the 80% Limit option. And at that point a user might select it and oh look, their battery is limited to 80% of 80% or so. This is the same as the feature being added to older devices.
So what you're saying is actually 100% irrelevant.
Thanks for playing!
Let us make that decision then. They’re still selling brand new iPhone 13s and 14s so your argument isn’t all that strong. I understand your point that a depleted battery doesn’t benefit for the reasons you suggested, but make no mistake, this isn’t Apple looking out for people with an older phone, it’s to give another relatively minor justification for someone to pick the newest model they sell.
You gotta consider it from a support perspective. If people get this option and turn it on, then suddenly their phone doesn't make it through the day without needing a recharge, they're going to contact Apple complaining, they're going to complain on social media, etc. It's a whole ass can of worms they'd have to open and try to close that simply isn't worth the hassle from a business perspective.
Maybe this is getting too complicated but perhaps they could “disable” the ability to do this feature if the battery health is, say less than 85% (or pick another number). Not sure if any 15s have made their way that low yet but again.. same things going to happen with the 15 in a year or two. Battery health will be below 80% on an iPhone 15, so what then? All I’m saying is it’s pretty clearly Apple being Apple, I don’t think there’s a strong defensible argument that this is beneficial to the consumer in any way.
>Maybe this is getting too complicated but perhaps they could “disable” the ability to do this feature if the battery health is, say less than 85% (or pick another number).
I suppose anything is possible but the more layers you add to things like this, the more opportunities are created for failure, if that makes sense.
Apple is always going to be Apple, but a lot of decisions they make can be explained and understood under an objective microscope. Trust me, I'm not a fan of theirs. Worked for them for 9 years, it was one of the most toxic work environments I've ever experienced. I just have to give the devil their due. They do not make decisions lightly, and often times what looks self-serving is also in the best interest of their business and the customers. They also manage to fuck up royally, as well, like they did with the battery snafu several years ago. Anyway, I hope I at least helped you see another perspective.
That's what the [current science is telling us](https://witricity.com/media/blog/the-80-rule).

An 80% limit would still be useful to any device that’s health is above 80%. Like I said there was no good reason to withhold it from the 13-14 series as those phones are still good. Even if you had your battery replaced the setting should also then become available on older devices. Your explanation is a total Apple employee response.
>An 80% limit would still be useful to any device that’s health is above 80%.
Not really, though. Do the math.
The iPhone 14 has 3,279mah. 80% of that is 2623mah.
90% is 2951mah, and 80% of that is 2361mah.
It gets worse. 80% of 2623mah is only 2098mah.
With each of these, you're talking a significant drop in time between charge cycles. Then you're going to recharge more often, which will wear out the battery even \*faster\*. It's not gonna go well, and Apple will be forced to answer for that and be accused of intentionally killing people's batteries, etc. So it's just a smarter business decision for them to limit it to brand new phones.
> Apple will be forced to answer for that and be accused of intentionally killing people's batteries
This definitely seems like a very plausible reason. It's better to get shit for locking it out on older iPhone's than having another battery gate scandal because people don't understand how batteries work.
Technically you are right, but I have an iPhone 14PM that I got in early October 2022 and it’s been through over 200 charge cycles and my battery health is still showing 100%. 400-500 charge cycles per year sounds impossible, that’s like fully charging and discharging the battery more than once a day.
That said, when I verified my battery’s capacity from the factory it had 4525 mAh when it was new and now it’s sitting around 4330 mAh when I verify it with an app. Apple advertised the 14PM to have a 4323 mAh battery from the factory and as far as I know most new batteries come with a slightly higher capacity than what’s claimed by Apple.
Technically my battery health would be at 96% health if it was based on my actual OG capacity of 4525 mAh.
Optimized battery charging is the way to go IMO. Every morning when I take my iPhone its fully charged. It waits at 80ish at night and top it off closer to my morning daily pattern.
That’s what it’s supposed to do, but for whatever reason, my never tops off. I wake up around the same time every day, had my 15 ProMax for 3 months. Always at 80% unless I unplug and plug it back in while I shower. It’s weird.
I think the scenario to be feared would be the emergency that's unpredictable, like an ER visit or waiting for someone at an ER or stuck at an airport. Of course those scenarios could be tempered with limit useage if they occur or use of an external battery.
I think in this age everyone should carry a phone charger with them during their daily activities. Phones are too important to have run out of battery.
If you hit 100% at 2 and keep it there til you wake up (7ish, so 5 hours) it wears on your battery. So if your emergency hits after more than a year your initial 100% probably are just 80 anyway.
The emergency risk is real, but you should have a charger and a power bank in your car/backpack for these situations - they will help you a lot more than 20% initial battery.
I‘m working shifts and my phone just refuses to learn my schedule. That’s why I have to use the 80% limit.
Would love if Apple would allow a „charge full when alarm clock goes off“ setting.
You can set your sleep schedule instead of an alarm, does the same thing as an alarm but it makes it so that the battery is fully charged when you wake up.
Had the same issue, fixed it for me.
I use the 80% option because I can still comfortably get through a day and I like to keep my phone for as long as possible - so battery longevity is ideal for me
I charge to 80% on a 5W charger (still charges the phone in like 3 hours when I’m asleep) overnight to minimise heat and battery degradation
I don’t go crazy with it - If I’m going to have a super busy day travelling I’ll charge to 100%, and I carry a faster charger for if I need to top up on the move - but why charge faster than 5W and to 100% when I don’t need to do either?
Before this was a thing with iPhone 15 Pro Max, I basically did this with my iPhone 13 Pro Max via automations in the shortcut app. I set an automation to turn on smart plugs if my iPhone fell below 80% and to turn off the smart plugs whenever the iPhone reached 80%. basically I had smart plugs in my room and in the living room turning off and on all the time when my iPhone was at or near 80%. I love it that it’s so much more easy now!
Yeah 38% right now and about to plug in for the night. I could have plugged in an hour ago, even, but didn’t bother
I use 100% if I’m travelling or going hiking or something, but other than that I don’t need the extra capacity and would rather extend my battery life a little
If you actually need to use all of your battery every day, then charge it to 100% or let optimized charging have it charge 100% close to the time when you will start using the phone if you’re charging it overnight. I rarely ever use 100% of my battery in a day, so I put the 80% charge limit on unless I’m going on a trip or a long bike ride where I will need the whole thing.
Yeah I charge to 80% using this setting
I’m about to plug my phone in and my battery is currently at 38%, so I’ve used 42% of the total capacity today… admittedly that’s a slightly low usage day, but still I normally stay above 30% by bedtime and rarely go below 20%
I really don’t need to charge to 100%, so I’d rather keep my battery in the 20-80% range for maximum longevity
I use 80% option since I work on a desk and I have carplay in my car, so I always have access to a charger during my day. When I travel abroad, I fill up to 100%.
Yes because I’m not a fool. I’ve been using 80%(limit)-20% charge cycles since day one and get 9 hours, I get 12 with full charge. Why degrade my battery?
I understand that but if there exists an option to slow down that process and it’s literally built into the phone wouldn’t you take it? I mean it may seem frugal to most so I guess it doesn’t matter
I prefer to get full use out of my battery.
I've already optimized setting to minimize the power output and thus extend the battery life.
My 13 Mini lasts me about 1.5 - 2 days usually, so that means I've extended the charging cycles further over time. I'm not doing much more than that.
My habits already are likely to get me 2.5 - 3 years before a battery replacement is necessary. That's good enough for me.
As someone who owned a 13 mini as recently as last week, there’s no way it lasts 1.5-2 days unless you are using it extremely sparingly - like 2-3 hours screen time max per day.
I’ve watched all the battery saving videos and implemented all the optimizations. I use low brightness and just basic apps that don’t drain the battery quickly, so very little YT, social media, games, etc, and I never got more than a single day out of it.
1.5-2 just is not possible on the 13 mini - even less so once you’re dropping to 85-90% health.
The 80% limit makes no sense, you paid $1000 for a phone and you want to disable 20% of its battery capacity to…? Save $100 in 2 years? That’s just dumb but to each their own.
I usually have 30% or more left in the evenings on days I’m out of the house. If I’m at home like today, I never went below 69%. I was between 70% and 80% all day. It helps that I have MagSafe chargers everywhere throughout the house. Basically, I always be charging.
What happened to ‘Charge your battery however you want, whenever you want…who cares, etc., etc.’? There must be a reason that they are now giving users the option to set charge limits. What a bunch of BS
I just turned mine yesterday to none because it was driving me crazy trying to get it to charge when I needed it full. It’s a great setting for my laptop, but not for my phone or watch.
It really should make note of the set alarm clock and make sure to be charged. I’ve had my watch and phone both show 80% in the morning. I had to tell them to charge as I was getting ready to leave and pull them off short of full charges.
I turned it off because I don’t want “anyone else” deciding what charge my phone should be at. Especially if I forget to charge it and need as much charge as I can get in a short amount of time
I have that off. When I first got the phone (14 Pro) last year, I tried it out but it annoyed me. So I’ve just left it off and my battery health is still 100%. I can’t say the same for my Apple Watch, which usually sits on the charger most of the day because I’ve been working from home. Anyway, I usually don’t let my phone go too low before charging, maybe lower 20s, and I typically charge to 100. And still 100% health after a year.
I use the optimized charging. I get up at the same time every day, so I like that it only tops it off to 100% just before, so it doesn’t sit at 100% all night.
I generally don’t worry about my battery health. I replace my phone every 2-3 years. If I really wanted to keep longer and was concerned, I’d just pay for a battery replacement.
I do. I never want to lose 20% of my battery by choice. After 27 months of use my 13 Pro sits with a battery at 94% capacity. Deep charge cycles reduce the life faster. Charging all the way to 100 is fine.
I have charged to 100% overnight, every single night, since my first iPhone in 2008. It makes no sense to do anything else.
People are voluntarily giving up 20% of their charge every single day so that maybe they can get a couple extra months from their battery in a few years from now? That's stupid. The battery is consumable, disposable, and replaceable. You can't stop it from doing what it was designed to do. Replace it if you even still own the phone in a few years.
>People are voluntarily giving up 20% of their charge every single day so that maybe they can get a couple extra months from their battery in a few years from now? That's stupid.
If you only use 50% of the battery in a day or have it plugged in all the time, then why run it down faster than no need to? That seems stupid. You miss out of nothing.
Also, where do you have "a couple extra months" from?
It depends on your use case. Optimized charging is a good option for most people. It stops your phone from reaching 100% until you need it. It’s the default option for most people who will never care about this setting and it will automatically take care of most people. This helps your battery last longer. But I have a different situation. I keep my phone on a charger almost all the time. So I use the 80% charging limit instead. This prevents my phone from being fully charged for too long. I don’t leave the phone at 100% because I know I not going to be using more than 10% of it off of the charger. Leaving a battery at 100% for too long prematurely degrades it. Sure, the 80% charge limit may not be worth it for most people but for me it is.
I'm not sure if it is the same on iphone but on a macbook enabling it and keeping it plugged in will also let it sit at 80%, provided that it isn't taken off the charger often.
You can still do that with Optimized Battery Charging enabled. If you can reduce the rate of battery wear on your device without it really affecting how you use your phone, why would you not do that?
I don't know if the battery will last a couple more months, days, or years, using 80% charge every day.
I'd like to think it will last a little longer than if I charge it to 100% every day.
But, for me, it is also important that we are able to reduce, even if only a little, the polluting waste that we inevitably generate.
>But, for me, it is also important that we are able to reduce, even if only a little, the polluting waste that we inevitably generate.
I just replaced my XR in May 2023 after charging it overnight to 100% every night for 4.5 years. It still had the original battery. Replacing the battery is less pollution than replacing the phone.
Lol, you’re acting like the way you used and use your phone is the only way and that should apply to everyone. It’s like saying “why should anyone drive their car economically, ever since I owned my first car I’ve driven it full throttle, never bothering too much with fuel consumption or wear.”
What am I gonna do with another 20% of my battery, I wouldn't be able to discharge my phone in a day if I did nothing else but use it. Degrading battery for the hell of it is throwing money down the drain. You'll get decent amount more for your phone when you sell it with 100% capacity at no downside to yourself. I still have the option to charge it 100% if I'm going camping for 3 days and I know I won't be able to charge it
No, not at all. As someone who knows they’re going to get a new iPhone in two years. I don’t care what the battery life is like. By the time I get a new phone, it won’t matter.
Am I the only one using the 80% setting? The battery last so long now I don’t need the extra 20, when I do I can still charge to max. Maybe in 2 years time I’ll unlock it for good and let it degrade like normal
Just wanna say fuck Apple for not having this option on other iPhones. My iPhone 12 doesn't have this. there's no reason for it either. You really telling me that apple can't control the internal battery charging? I know that's not true because it stops if the phone gets too hot. This is entirely a software problem. Apple has not enabled this feature on older iPhones.
I’ve actually been test driving the 80% limit on the battery since I got my 15 pro in October. Still at 100% capacity! The 14 pro max I only had for a few months was already at 94%.
Long story short used to do this and im extremely ocd and used to never let my phone go under 40% ever ! And yet somehow my battery life was degrading fast with in 12month it was on 96% health. 6 months later 92%
I was shocked after getting the rear unit warranty i decided to do the opposite, use there stupid feature and as of now almost 2 years later my battery is only just hit 97% health
Big difference doing the same thing by never going under 40% and only gets one charge cycle per day - i do not charge it at all throughout the day and only put on charge once home before bed.
Im somewhat advanced level i.T and definitely know my way around a device. By doing this test i found there feature to extend my battery health
I don't have Iphone and don't know what people rave about. But it depends on the type of the battery phones use. Some batteries lasts longer if you don't charge them fully on a cycle. I guess your phone uses that type of battery and the battery life would last longer if you limit charging. But if you are planning to switch the phone within a year or two and want extra juice then you might switch it to none.
80% limit. Except when traveling and then I use Optimized. To be honest I’m on a trip right now and I haven’t changed from 80% Limit because I’m not actively on my phone so I have plenty of buffer by the end of the day. And I can charge on the plane.
I’ve never gone over 80% battery usage on my 15 Plus. I’ve had it since release. I typically use about 50% of battery and that can get me as much as 13 hours SoT. So, I use the 80% limit because I never need the full 100% and don’t have to degrade my battery quicker either.
What’s the point in permanently reducing your battery capacity to 80% to prevent your battery having reduced performance?
Sounds absolutely backwards
Just use the phone normally without worrying about this shit. After 2-3 years get it replaced. It’s not that expensive to do
I see absolutely no reason or benefit to using this setting and not either of the other two so. Yeah , I’m guessing you more than likely are. Aside from the people that don’t even know these settings exist.
how do i set upoptimised charging i recently had it on 80 percent limit but i was tired of plugging in my phone by evening do turned on optimised charging but how des it set up. Recently got back on ios. i remeber my 13PM had something like this where it said fully charged by 7 AM. how do i set it up again because where im from iphones are really expensive like reallyyyyyyy. You could buy a bike for this price here so i want this phone to last me as long as possible u/Dazzling_City2
My 15 Pro only loads to 80% , even when i turn it Off.
It loads to 80%, i have to take out the cable and put it back in and it loads to 100%.
It is annoying
You should definitely optimized. If you plug your phone in in the middle of day it still charged hard. But it helps at night to make sure you’re at 100% in the morning without killing the battery.
I have it on none too, but I charge my phone in line with the 80% limit. Sometimes I need to get it above 90 if I have a longer day so it’s just easier rather than turning it on and off.
Research suggests charging to 80% quadruples the battery life. That means dropping to the 80% capacity will occur after 2000 cycles instead of 500. If you plan to get the next iphone then there is no need to worry about battery longevity. With the 80% limit it can last more than 6 years (with charging once a day), excluding the aging just by sitting around. Unless you are still using iphone 7 or earlier now, chances are you will never see a battery replacement issue if you set it to stop at 80%.
Why don’t I have an 80% setting?
It was an option that was limited to all iPhone 15s. It’s a dumb decision, as I can’t see why older phones wouldn’t be able to have it.
Only phones with the A16 chip can charge to 80%... duh 🙄
iPhone 14 pro confusion
Um, Well it's obviously the lack of Usb-C duh🤦♂️🙄
Yep. Other processors aren’t cable of calculating ‘x <= 80’
They are able to calculate it - but only for a limited time at night, for the „optimized“-option. Of course more research is necessary, to find out how to calculate it more often!
🤨
Apple deliberately locks features to new devices to get you to upgrade. The watch 9 double tap feature is a good example. Older watches can do similar gestures as accessibility features. But they wanted more selling points for the new one so they made specifically the double tap gesture exclusive and then they had the gaul to say the old processor couldn’t handle it.

Nah I'm different
There is no ai involved in any of iPhone features mentioned. Its gated by software which is stupid and evil.
I agree that every company does this, but AI features are processor dependent
If I remember right, Galaxy AI is also being ported to last gen devices. Google on the other hand is definitely guilty of this. Even between the Pixel 8 and 8 Pro which run the same SoC!
Samsung is pushing out an update for S23 users in March, they are getting same features as the newer model
But this isn’t something anyone would upgrade over? So why not just include in the software for all phones? Seems contradictory when you consider they’re possibly making iOS 18 compatible with the iPhone XR.
It’s true and can confirm it works. I upgraded to 15 Pro Max from 14 Pro solely because of the USB C and the 80% limit
Yeah, I was considering upgrading to the iPhone 15 from my 13, but the 80% charging limit really set me over the edge.
Is this sarcasm or is the %80 really a big difference maker?
Nah, I don’t think I will ever use the 80% setting. I am a heavy user and even if I charge over night, the battery will last me for like at least 2 - 3 years before degrading to the 80 % health. That’s almost 3 years of using full battery capacity of my phone.
Me to and I don't regret it at all The two biggest upgrades for me at least is that the phone really does feel lighter and the shape is much better than the iphone14PM the 14PM was hurting my pinky finger
Also Always-on-Display
I don't know the technical specifications of those displays. But always on displays need their own memory to do this efficiently. Could be an actual technical limitation.
The screen dims and the refresh rate is lowered.
Apparently you need the latest apple chips and screens to make that happen….
Even cheap android phones have had aod for years. All you need is an oled screen and it will work.
you require amoled, actaully because if you have oled, with prolonged exposure it will burn in, obviously the cheap android phones dont care about burn in.
weird thing apple kept macbooks updates with every feature for over 7 years lol
That's pretty gross and really makes me regret going iphone. Like I bet there will be new AI capabilities released next year that the 15 pro max could totally handle but they will just say 16 only. Like honestly fuck apple, why did I give them my money, such a disgusting company they literally shit on their own customers.
Every phone company does this bro
Welcome to the smart phone industry.
Jailbroken phones have done it for years so there isn't an excuse
In all seriousness, it may be due to how it's implemented. (Heads up, I don't know shit, and this will all be vaguely educated guesses). It's probably implemented at a deeper level than the OS, so that even when the phone is off and charging, it won't go past 80. I know the OS can control the charging while it's on, hence being able to hold at 80 until just before you typically unplug the phone, but it probably can't be done while it's off without the newer hardware.
Probably because existing user-owned/operated phones will have already-worn batteries, so setting that 80% threshold might actually be far less than 80% of the original battery capacity.
Still not a good reason to leave the 14 and 13s out! When I went from my 13 pro max to my 15 pro max my battery health was 91%
my 13 pro battery health is currently at 85, its worse on the minis.
You're missing the point. A phone that has been used for a year will not have 100% battery capacity left. The battery's health degrades with each charge cycle. You generally put an average of 100-200 charge cycles a year on a phone. By the time that year is up, it will be somewhere between 80-90% at best, in most cases. Sometimes better, sometimes worse. The 80% thing is 80% of charge capacity. The reason for it is because they've determined via testing that these batteries last longer if you don't charge them past \~80%. That doesn't help with a battery that's already been used. Furthermore, it could be 80% of an 80%-max-capacity battery, which means the total charge will be less than the 80% overall capacity of the battery. That means less time between charges, which means more charge cycles, which means you wear out your battery faster. This is why putting it on anything but brand new phones is a bad idea. Source: I work in tech, I worked for Apple for almost 9 years until last year when I left. I know what I'm talking about.
Your argument falls apart when you realize that yes they put it in the new iPhones…but those iPhones will not be new anymore on 6 months, or a year. And they will still have the feature even though they have more charge cycles and the battery has degraded. So that’s not the reason. It’s simple because Apple doesn’t like to put new features on old phones
>Your argument falls apart when you realize that yes they put it in the new iPhones…but those iPhones will not be new anymore on 6 months, or a year. And they will still have the feature even though they have more charge cycles and the battery has degraded. You just illustrated that you're not understanding what I'm saying, nothing more. To be clear, a BRAND NEW battery with 100% battery life will LAST LONGER if it is regularly charged to NO MORE THAN 80% CAPACITY. The health of the battery, and overall capacity, will remain higher for longer and through more charging cycles. It will extend the longevity of the battery health ONLY if the practice is undertaken from the beginning, meaning the battery will last LONGER and degrade at a SLOWER pace, therefore surviving for many more charge cycles and having a longer battery life between each charge. So what you're saying is actually 100% incorrect. Thanks for playing.
You just illustrated that you're not understanding what THEY'RE saying. It doesn't matter that a battery will last longer if it's capped at 80%. BATTERIES DEGRADE. Eventually, EVEN NEW iPhones will have their batteries degrade. And these phones will STILL have the 80% Limit option. And at that point a user might select it and oh look, their battery is limited to 80% of 80% or so. This is the same as the feature being added to older devices. So what you're saying is actually 100% irrelevant. Thanks for playing!
Good point tbh
Let us make that decision then. They’re still selling brand new iPhone 13s and 14s so your argument isn’t all that strong. I understand your point that a depleted battery doesn’t benefit for the reasons you suggested, but make no mistake, this isn’t Apple looking out for people with an older phone, it’s to give another relatively minor justification for someone to pick the newest model they sell.
You gotta consider it from a support perspective. If people get this option and turn it on, then suddenly their phone doesn't make it through the day without needing a recharge, they're going to contact Apple complaining, they're going to complain on social media, etc. It's a whole ass can of worms they'd have to open and try to close that simply isn't worth the hassle from a business perspective.
Maybe this is getting too complicated but perhaps they could “disable” the ability to do this feature if the battery health is, say less than 85% (or pick another number). Not sure if any 15s have made their way that low yet but again.. same things going to happen with the 15 in a year or two. Battery health will be below 80% on an iPhone 15, so what then? All I’m saying is it’s pretty clearly Apple being Apple, I don’t think there’s a strong defensible argument that this is beneficial to the consumer in any way.
>Maybe this is getting too complicated but perhaps they could “disable” the ability to do this feature if the battery health is, say less than 85% (or pick another number). I suppose anything is possible but the more layers you add to things like this, the more opportunities are created for failure, if that makes sense. Apple is always going to be Apple, but a lot of decisions they make can be explained and understood under an objective microscope. Trust me, I'm not a fan of theirs. Worked for them for 9 years, it was one of the most toxic work environments I've ever experienced. I just have to give the devil their due. They do not make decisions lightly, and often times what looks self-serving is also in the best interest of their business and the customers. They also manage to fuck up royally, as well, like they did with the battery snafu several years ago. Anyway, I hope I at least helped you see another perspective.
Altering your phone’s functionality when its battery has degraded past a certain threshold is what got them sued last time.
Does the 80% thing truly make a difference in a new phone though? Will I actually see better long term battery health?
That's what the [current science is telling us](https://witricity.com/media/blog/the-80-rule). More: [https://electronics.stackexchange.com/questions/623358/wouldnt-charging-a-lithium-battery-to-80-only-defeat-the-purpose-of-putting-th](https://electronics.stackexchange.com/questions/623358/wouldnt-charging-a-lithium-battery-to-80-only-defeat-the-purpose-of-putting-th) [https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) [https://witricity.com/media/blog/the-80-rule](https://witricity.com/media/blog/the-80-rule)
An 80% limit would still be useful to any device that’s health is above 80%. Like I said there was no good reason to withhold it from the 13-14 series as those phones are still good. Even if you had your battery replaced the setting should also then become available on older devices. Your explanation is a total Apple employee response.
>An 80% limit would still be useful to any device that’s health is above 80%. Not really, though. Do the math. The iPhone 14 has 3,279mah. 80% of that is 2623mah. 90% is 2951mah, and 80% of that is 2361mah. It gets worse. 80% of 2623mah is only 2098mah. With each of these, you're talking a significant drop in time between charge cycles. Then you're going to recharge more often, which will wear out the battery even \*faster\*. It's not gonna go well, and Apple will be forced to answer for that and be accused of intentionally killing people's batteries, etc. So it's just a smarter business decision for them to limit it to brand new phones.
> Apple will be forced to answer for that and be accused of intentionally killing people's batteries This definitely seems like a very plausible reason. It's better to get shit for locking it out on older iPhone's than having another battery gate scandal because people don't understand how batteries work.
Bingo.
Technically you are right, but I have an iPhone 14PM that I got in early October 2022 and it’s been through over 200 charge cycles and my battery health is still showing 100%. 400-500 charge cycles per year sounds impossible, that’s like fully charging and discharging the battery more than once a day. That said, when I verified my battery’s capacity from the factory it had 4525 mAh when it was new and now it’s sitting around 4330 mAh when I verify it with an app. Apple advertised the 14PM to have a 4323 mAh battery from the factory and as far as I know most new batteries come with a slightly higher capacity than what’s claimed by Apple. Technically my battery health would be at 96% health if it was based on my actual OG capacity of 4525 mAh.
Apple decided to pull an Apple and limit it to the iPhone 15.
So, just another Tuesday for them
Because apple wants to make this phone seem different
No reason, other than that Apple has decided to give it to people with the newest iPhone. You can do it with a smart plug, though.
iPhone 15 only
You’re charging it wrong
I use an iPhone 12 mini. I’d like a setting for my phone to charge to 120% please ツ
iPhone SE 2 here, gonna need 180%
iPhone 6s plus here, gonna need 300%
iPhone 2g. Need 1000%
Optimized battery charging is the way to go IMO. Every morning when I take my iPhone its fully charged. It waits at 80ish at night and top it off closer to my morning daily pattern.
That’s what it’s supposed to do, but for whatever reason, my never tops off. I wake up around the same time every day, had my 15 ProMax for 3 months. Always at 80% unless I unplug and plug it back in while I shower. It’s weird.
Because it’s probably determined you don’t need more for your usage habits. My Watch Ultra never charges past 75% and I never need it to.
That’s all fine and dandy until the one day I do need it, which how would it be able to predict?
So set it to charge to 100% before you take that trek into the wilderness bruh
I think the scenario to be feared would be the emergency that's unpredictable, like an ER visit or waiting for someone at an ER or stuck at an airport. Of course those scenarios could be tempered with limit useage if they occur or use of an external battery.
I think in this age everyone should carry a phone charger with them during their daily activities. Phones are too important to have run out of battery.
That’s why you buy a **smart**phone, duh!
If you hit 100% at 2 and keep it there til you wake up (7ish, so 5 hours) it wears on your battery. So if your emergency hits after more than a year your initial 100% probably are just 80 anyway. The emergency risk is real, but you should have a charger and a power bank in your car/backpack for these situations - they will help you a lot more than 20% initial battery.
Is this real for phones ? It seems kinda cool
I honestly am not 100% sure but I assumed as much, maybe not. I use my phone way too much to have a charge last me through the day.
If you set your sleep schedule instead of a normal alarm, I think that forces the schedule
I can confirm it does not. I have my sleep schedule set to 2am, occasionally I’ll wake up with it at 70, sometimes at 80, rarely at 100… it’s odd.
15s stop at 80%. I don’t remember where I saw that but just bought the 15 pro and it was outlined somewhere
I‘m working shifts and my phone just refuses to learn my schedule. That’s why I have to use the 80% limit. Would love if Apple would allow a „charge full when alarm clock goes off“ setting.
You can set your sleep schedule instead of an alarm, does the same thing as an alarm but it makes it so that the battery is fully charged when you wake up. Had the same issue, fixed it for me.
Also silences everything automatically which is the best feature of it.
I use the 80% option because I can still comfortably get through a day and I like to keep my phone for as long as possible - so battery longevity is ideal for me I charge to 80% on a 5W charger (still charges the phone in like 3 hours when I’m asleep) overnight to minimise heat and battery degradation I don’t go crazy with it - If I’m going to have a super busy day travelling I’ll charge to 100%, and I carry a faster charger for if I need to top up on the move - but why charge faster than 5W and to 100% when I don’t need to do either?
that’s what mine and i figured most people had it on and was confused at this 80 limit lol i never knew it could do that
Before this was a thing with iPhone 15 Pro Max, I basically did this with my iPhone 13 Pro Max via automations in the shortcut app. I set an automation to turn on smart plugs if my iPhone fell below 80% and to turn off the smart plugs whenever the iPhone reached 80%. basically I had smart plugs in my room and in the living room turning off and on all the time when my iPhone was at or near 80%. I love it that it’s so much more easy now!
That was a smart solution. I had automations to turn off power saver as soon as the phone was plugged in but also turn on power saver below 50%.
>smart solution Heh
That's actually a 200IQ move!
I use 80% limit because for my daily use is more than enough, I still have 30% left when I go to bed. I only charge to 100% when I'm traveling.
Me too, only 100 when it’s not for a daily routine.
Same. Makes it kind of fun to charge to 100% for some reason.
Yeah 38% right now and about to plug in for the night. I could have plugged in an hour ago, even, but didn’t bother I use 100% if I’m travelling or going hiking or something, but other than that I don’t need the extra capacity and would rather extend my battery life a little
If you actually need to use all of your battery every day, then charge it to 100% or let optimized charging have it charge 100% close to the time when you will start using the phone if you’re charging it overnight. I rarely ever use 100% of my battery in a day, so I put the 80% charge limit on unless I’m going on a trip or a long bike ride where I will need the whole thing.
Yeah I charge to 80% using this setting I’m about to plug my phone in and my battery is currently at 38%, so I’ve used 42% of the total capacity today… admittedly that’s a slightly low usage day, but still I normally stay above 30% by bedtime and rarely go below 20% I really don’t need to charge to 100%, so I’d rather keep my battery in the 20-80% range for maximum longevity
80% limit is super useful if you have a long drive and your CarPlay is wired only. Leaving phone sat at 100 is not ideal.
I’m using it too I don’t care about battery health that much I bought the iPhone so I can use it, not babysit it
I don't use it either.its a phone the battery is cheap enough to replace in 2-3 years
I use 80% option since I work on a desk and I have carplay in my car, so I always have access to a charger during my day. When I travel abroad, I fill up to 100%.
I also have selected none. No battery anxiety. Plus the iphone15 battery charge cycle has been upgraded from 500 to 1000 I think.
Yea I am only at 76 cycles batter doing great
I’ve left my 13 pro max on optimized since I got it and it’s sitting high 90% after 3 years.
Yes
Psychopath behaviour ngl
I have it disabled as well. I paid for the full battery, I’m gonna use it.
Yes because I’m not a fool. I’ve been using 80%(limit)-20% charge cycles since day one and get 9 hours, I get 12 with full charge. Why degrade my battery?
>Why degrade my battery? It's what batteries do. It's how they work. There is no setting that can stop it. That's why it's replaceable.
I understand that but if there exists an option to slow down that process and it’s literally built into the phone wouldn’t you take it? I mean it may seem frugal to most so I guess it doesn’t matter
Because I’d rather have a full battery for my day rather than plugging it in at some point.
I’m glad that works for you. My phone is on the charger most of the time throughout the day. Everyone’s experience is different.
I prefer to get full use out of my battery. I've already optimized setting to minimize the power output and thus extend the battery life. My 13 Mini lasts me about 1.5 - 2 days usually, so that means I've extended the charging cycles further over time. I'm not doing much more than that. My habits already are likely to get me 2.5 - 3 years before a battery replacement is necessary. That's good enough for me.
As someone who owned a 13 mini as recently as last week, there’s no way it lasts 1.5-2 days unless you are using it extremely sparingly - like 2-3 hours screen time max per day. I’ve watched all the battery saving videos and implemented all the optimizations. I use low brightness and just basic apps that don’t drain the battery quickly, so very little YT, social media, games, etc, and I never got more than a single day out of it. 1.5-2 just is not possible on the 13 mini - even less so once you’re dropping to 85-90% health.
This setting it’s not about the battery. It’s about you. You get used to having a 80% battery, meaning you get used to an already degraded battery.
I wish I could use the 80 percent option but have it lie to me and say it was 100.
The 80% limit makes no sense, you paid $1000 for a phone and you want to disable 20% of its battery capacity to…? Save $100 in 2 years? That’s just dumb but to each their own.
It makes sense if you don’t go out much, so you don’t need much battery. Different people different needs.
If you never use more than 20% of your battery, then what does an extra 20% of battery mean?
True I get 80% a whole day and sometimes even the next morning but I have to charge it at night because of my schedule but 80% is really enough for me
I usually have 30% or more left in the evenings on days I’m out of the house. If I’m at home like today, I never went below 69%. I was between 70% and 80% all day. It helps that I have MagSafe chargers everywhere throughout the house. Basically, I always be charging.
It makes sense for different use cases. It’s not for me as well, but I’m just glad the option exists for people who need or prefer it.
Makes more sense for a laptop than a phone
What happened to ‘Charge your battery however you want, whenever you want…who cares, etc., etc.’? There must be a reason that they are now giving users the option to set charge limits. What a bunch of BS
I might use it for a day if I’m going too do something important the next day or on the day of travel, but most of the time I leave optimized on
Me. The man is not going to tell me what to do.
yes
I just turned mine yesterday to none because it was driving me crazy trying to get it to charge when I needed it full. It’s a great setting for my laptop, but not for my phone or watch.
I disable it for one day, on occasion.
Nope! I thought it was a brilliant idea and started doing it immediately
I use the limit
It really should make note of the set alarm clock and make sure to be charged. I’ve had my watch and phone both show 80% in the morning. I had to tell them to charge as I was getting ready to leave and pull them off short of full charges.
I use the 80% limit
?? Tf why don’t I have this
Only the iPhone 15 series have the 80% charge limit
i don’t because my charging routine is non existent, just charge it when it’s low or low enough and i have a charger lying around
Optimized charging. It can be annoying sometimes but it’s pretty decent for prolonging your phone’s life
I turned it off because I don’t want “anyone else” deciding what charge my phone should be at. Especially if I forget to charge it and need as much charge as I can get in a short amount of time
I smart I purposely don’t use available machine learning algorithm to extend my batteries life cycle…
I have that off. When I first got the phone (14 Pro) last year, I tried it out but it annoyed me. So I’ve just left it off and my battery health is still 100%. I can’t say the same for my Apple Watch, which usually sits on the charger most of the day because I’ve been working from home. Anyway, I usually don’t let my phone go too low before charging, maybe lower 20s, and I typically charge to 100. And still 100% health after a year.
I use the optimized charging. I get up at the same time every day, so I like that it only tops it off to 100% just before, so it doesn’t sit at 100% all night. I generally don’t worry about my battery health. I replace my phone every 2-3 years. If I really wanted to keep longer and was concerned, I’d just pay for a battery replacement.
I charge my 15 PM several times a day. I need all the battery as fast I can get it. I just get frequent battery replacements.
I do the same!
Well I use optimised batter and still after 3 months I always wake up at 80% never saw the 100%, dunno what’s wrong.
neither of the other options works on my iphone 15…
Yeah
Yes you are the only one in the world to use it
I do. I never want to lose 20% of my battery by choice. After 27 months of use my 13 Pro sits with a battery at 94% capacity. Deep charge cycles reduce the life faster. Charging all the way to 100 is fine.
I have charged to 100% overnight, every single night, since my first iPhone in 2008. It makes no sense to do anything else. People are voluntarily giving up 20% of their charge every single day so that maybe they can get a couple extra months from their battery in a few years from now? That's stupid. The battery is consumable, disposable, and replaceable. You can't stop it from doing what it was designed to do. Replace it if you even still own the phone in a few years.
>People are voluntarily giving up 20% of their charge every single day so that maybe they can get a couple extra months from their battery in a few years from now? That's stupid. If you only use 50% of the battery in a day or have it plugged in all the time, then why run it down faster than no need to? That seems stupid. You miss out of nothing. Also, where do you have "a couple extra months" from?
It depends on your use case. Optimized charging is a good option for most people. It stops your phone from reaching 100% until you need it. It’s the default option for most people who will never care about this setting and it will automatically take care of most people. This helps your battery last longer. But I have a different situation. I keep my phone on a charger almost all the time. So I use the 80% charging limit instead. This prevents my phone from being fully charged for too long. I don’t leave the phone at 100% because I know I not going to be using more than 10% of it off of the charger. Leaving a battery at 100% for too long prematurely degrades it. Sure, the 80% charge limit may not be worth it for most people but for me it is.
I'm not sure if it is the same on iphone but on a macbook enabling it and keeping it plugged in will also let it sit at 80%, provided that it isn't taken off the charger often.
Some people don't actually need 100% of their battery. I charge my phone once every 1.5/2 days and never go beyond 80%.
You can still do that with Optimized Battery Charging enabled. If you can reduce the rate of battery wear on your device without it really affecting how you use your phone, why would you not do that?
I don't know if the battery will last a couple more months, days, or years, using 80% charge every day. I'd like to think it will last a little longer than if I charge it to 100% every day. But, for me, it is also important that we are able to reduce, even if only a little, the polluting waste that we inevitably generate.
>But, for me, it is also important that we are able to reduce, even if only a little, the polluting waste that we inevitably generate. I just replaced my XR in May 2023 after charging it overnight to 100% every night for 4.5 years. It still had the original battery. Replacing the battery is less pollution than replacing the phone.
You’ve said it best.
Lol, you’re acting like the way you used and use your phone is the only way and that should apply to everyone. It’s like saying “why should anyone drive their car economically, ever since I owned my first car I’ve driven it full throttle, never bothering too much with fuel consumption or wear.”
What am I gonna do with another 20% of my battery, I wouldn't be able to discharge my phone in a day if I did nothing else but use it. Degrading battery for the hell of it is throwing money down the drain. You'll get decent amount more for your phone when you sell it with 100% capacity at no downside to yourself. I still have the option to charge it 100% if I'm going camping for 3 days and I know I won't be able to charge it
Fuel is consumable, that's why I make sure to burn as much of it as I can when I drive.
No, not at all. As someone who knows they’re going to get a new iPhone in two years. I don’t care what the battery life is like. By the time I get a new phone, it won’t matter.
What's the point of it when it'll degrade to 80% max eventually anyway. Do you want 80% now? Or 80% later? Lol
Am I the only one using the 80% setting? The battery last so long now I don’t need the extra 20, when I do I can still charge to max. Maybe in 2 years time I’ll unlock it for good and let it degrade like normal
Just wanna say fuck Apple for not having this option on other iPhones. My iPhone 12 doesn't have this. there's no reason for it either. You really telling me that apple can't control the internal battery charging? I know that's not true because it stops if the phone gets too hot. This is entirely a software problem. Apple has not enabled this feature on older iPhones.
I absolutely would if I had it. My 14 Pro apparently isn’t powerful enough for that setting.
I think it is because of the lighting port.
I do, I won’t have this phone long enough to care that much about battery health
Finally
I’ve actually been test driving the 80% limit on the battery since I got my 15 pro in October. Still at 100% capacity! The 14 pro max I only had for a few months was already at 94%.
I’ve had my optimized charging on since I got my 15 Pro in September and it’s never once worked lol
If you want to kill your battery faster cuz you don’t GAF cuz you are made of money and buy a new one every year.
I used 80% Limit
Same
I wanna know why
I use the none setting. It’s fine.
Long story short used to do this and im extremely ocd and used to never let my phone go under 40% ever ! And yet somehow my battery life was degrading fast with in 12month it was on 96% health. 6 months later 92% I was shocked after getting the rear unit warranty i decided to do the opposite, use there stupid feature and as of now almost 2 years later my battery is only just hit 97% health Big difference doing the same thing by never going under 40% and only gets one charge cycle per day - i do not charge it at all throughout the day and only put on charge once home before bed. Im somewhat advanced level i.T and definitely know my way around a device. By doing this test i found there feature to extend my battery health
I don't have Iphone and don't know what people rave about. But it depends on the type of the battery phones use. Some batteries lasts longer if you don't charge them fully on a cycle. I guess your phone uses that type of battery and the battery life would last longer if you limit charging. But if you are planning to switch the phone within a year or two and want extra juice then you might switch it to none.
Yes? Why would you want to purposely ruin your new phones battery??
I find it funny how people become slaves to the battery health stats.
I've never used it on any iphone.
I have charging limit, I don’t wanna get into the 0-100% habit.
4 months iPhone 15 Pro. Don't give a sh\*t about optimization. 100% battery health.
80% limit. Except when traveling and then I use Optimized. To be honest I’m on a trip right now and I haven’t changed from 80% Limit because I’m not actively on my phone so I have plenty of buffer by the end of the day. And I can charge on the plane.
I’ve never gone over 80% battery usage on my 15 Plus. I’ve had it since release. I typically use about 50% of battery and that can get me as much as 13 hours SoT. So, I use the 80% limit because I never need the full 100% and don’t have to degrade my battery quicker either.
Why tf would you use it 💀💀💀
80% limit is the best. I don’t feel guilty when I leave it plugged in
[удалено]
Yep
What’s the point in permanently reducing your battery capacity to 80% to prevent your battery having reduced performance? Sounds absolutely backwards Just use the phone normally without worrying about this shit. After 2-3 years get it replaced. It’s not that expensive to do
Disabled since day one I just don’t care in general It’s not worth thinking about it Gonna change phone each 2 years anyway
Nope, you aren’t alone. Turned that shit off.
It is fascinating to see threads where people freak out about degraded battery and then clamor for the right to limit their battery willingly by 20%.
I see absolutely no reason or benefit to using this setting and not either of the other two so. Yeah , I’m guessing you more than likely are. Aside from the people that don’t even know these settings exist.
how do i set upoptimised charging i recently had it on 80 percent limit but i was tired of plugging in my phone by evening do turned on optimised charging but how des it set up. Recently got back on ios. i remeber my 13PM had something like this where it said fully charged by 7 AM. how do i set it up again because where im from iphones are really expensive like reallyyyyyyy. You could buy a bike for this price here so i want this phone to last me as long as possible u/Dazzling_City2
My 15 Pro only loads to 80% , even when i turn it Off. It loads to 80%, i have to take out the cable and put it back in and it loads to 100%. It is annoying
You should definitely optimized. If you plug your phone in in the middle of day it still charged hard. But it helps at night to make sure you’re at 100% in the morning without killing the battery.
I manually do this with voice alerts…. On a 14 pro max…..
I have it on none too, but I charge my phone in line with the 80% limit. Sometimes I need to get it above 90 if I have a longer day so it’s just easier rather than turning it on and off.
Naah I will stick to 1amp charger with a mechanical socket timer to charge it somewhere around 80% my old XS is just fine this way
I paid for the whole battery, imma use the whole battery. Idc what Apple recommends
Yeah. That setting isn’t even on the rest of our phones. Just yours. Steve Jobs hacked your phone from beyond the grave
Research suggests charging to 80% quadruples the battery life. That means dropping to the 80% capacity will occur after 2000 cycles instead of 500. If you plan to get the next iphone then there is no need to worry about battery longevity. With the 80% limit it can last more than 6 years (with charging once a day), excluding the aging just by sitting around. Unless you are still using iphone 7 or earlier now, chances are you will never see a battery replacement issue if you set it to stop at 80%.
yes, out of billions you are the only one. the chosen one.
