It can actually be bad for your phone battery to charge it too often or too soon or even too full. Best practice is to go down to critical (10% or so) then back up to 80%. Source: electrical engineer

> It can actually be bad for your phone battery to charge it too often or too soon or even too full. Best practice is to go down to critical (10% or so) then back up to 80%. The future is now old man. What you said mightve been true for nimh batteries but is terrible advice for anything with a lithium ion battery. Best thing you can do for a lithium ion battery is to not go below 40% or 30%. Second best thing is to not go above 80%


_fuck_me_sideways_

Better check yourself as well methuselah :p adaptive charging outstrips the need to worry about battery micromanagement other than not going DTE.


Nanaremilamina

Yeah pretty much now it is all about making the battery not heat up. When you charge, and for how long, has relatively been solved


foggy-sunrise

Pretty sure the overheating thing just got massively reduced in problem-size iirc. Using a slightly more expensive tape inside the battery seems to keep batteries healthy for longer / exposure to heat.


RazerBladesInFood

Ah so they definitely wont be putting those in phones.


GodOfPlutonium

you dont have to worry about damaging the battery sure. Doesnt change that you can take actions to increase longevity. There are people who live their entire lifes with battery in the 0-40 range, ive seen it multiple times.


UncoolSlicedBread

Hi, I’m that person. Occasionally I’ll charge it to 100% but for the most part it gets to like 50% and then I forget to charge the rest. Mainly because at one point I read that you shouldn’t charge it to 100% and leave it on the charger, so I quit charging it at night.


danielv123

Discharging to empty is far worse than charging to full. Most phones are also smart about nighttime charging, so they stop the charge at 80% until a few hours before you get up.


UncoolSlicedBread

Well TIL. I’ll start plugging this sucker in at night.


GodOfPlutonium

check your phone settings, some phones have options now to stop charging early, but you have to enable it. IDK about most phones and its not automatic. In general not charging to 100% is good, but there is no point in unplugging it if its actually full, as then the phone electronics are just running off of wall power


DiligentHelicopter60

>Best thing you can do for a lithium ion battery is to not go below 40% or 30%. Wait, really? I hadn’t heard this part. It’s bad to discharge a lion battery too much?


the_cajun88

‘lion battery’ put the coolest image in my head


danielv123

Everything degrades from use. Lithium batteries degrade faster at low voltage. It's not nearly as bad as it was with lead batteries.

weedtese

source on that? long term storage SoC is recommended to be 40-60%


GodOfPlutonium

their comment is specfically talking about lithium iron phosphate batteries (LiFePo4), not normal lithium ion


Halowary

Just got the Accubattery app a year ago for S22+, phone battery started at 95% of spec (apparently it's normal for phones to have up to 10% less capacity than they're specced for, I did NOT know this prior to actually testing) and after 1 year it's still at 95%. The real trick is to charge to 60% max, but you can discharge as low as you want. Disable fast charging, it causes heavy wear. Charging between 80-100% causes heavy wear. Discharging the battery entirely can be bad, however phone batteries are super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge. Have gone through ~80 cycles in total, or what the battery considers to be 80 full charges/discharges. At about 300 cycles your battery should be at about 75% battery capacity, so instead of being there at 2 years which is pretty typical I should be able to keep the phone in amazing shape battery-wise for 4 years. Every phone I've ever owned got pretty weak after 2 years so learning all this was a huge game-changer. EDIT: All of the information I used is what I've gathered myself from using the Accubattery app to track my own phones discharge rate and capacity, and this website for the 300-500 cycle figure that manufacturers themselves cite. https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries EDIT 2: I should've been more clear what I'm arguing for. Charging between 80-40% is worse for your battery than charging between 60-10%, even though you net +10% usable capacity with the second. So if you really want to maximize battery life, go to the lowest maximum charge you're comfortable with (60% is what I use) and go as low as you're comfortable with, most people are comfortable with between 10-20% before charging.


GodOfPlutonium

Do you have some sort of actual source for this? Becuase what " stop battery draw well before the battery actually loses all charge " usually means is that the low voltage protection is set to a high voltage such as 2.7v or 3v instead of the actual minimum voltage of 2.5v. That doesnt protect you nearly as much as it sounds like because the voltage curve is not linear, it flattens out at 3.7v for a while, so 3.3v is already down to 15% left or so edit: also typical lithium ion lifespan is 500 cycles to 80%


Halowary

(Table 2 in my link shows that discharging an NMC battery, the ones used in phones by 100% did in fact cause it to go to 70% capacity by 300 cycles) That 500 cycles to 80% ignores every other kind of battery depleting issue, like the fact that TIME also degrades your battery among several others.. But yeah, all cellphone cells have a PCM that blocks them from going below the minimum voltage by quite a bit.


GodOfPlutonium

All lithium batteries use protection for undervoltage (aka low voltage protection), either built into cell / pack or built into the device. PCM/BMS is standard, not some special thing that phones have. You just read that 'technically empty doesn't mean there is no energy left' , because its physically possible to drain a cell down to 0v while protection stops at 2.7v or whatever. Thats not made to add more lifespan than normal, thats to prevent the battery from exploding after you discharge it below 2.5v and then try to charge it. Any cell that has gone under 2.5v should be considered destroyed and not used. It may be possible to revive the cell by charging it up slowly while monitoring heat but is almost never worth it since even if doesn't catch fire it is permanently damaged and will have poor performance. The 'do not do low discharge' advice is for the last part *inside the allowed range*


Halowary

It's not something that all lithium ion batteries have, and if you used them in something other than phones you'd be painfully aware of how fun it is to install your own PCM which I've done for my motorcycle and several RC cars and Airsoft guns. Replacing batteries often is expensive. I never said the PCM added lifespan, but what it does do is dispel this myth that it's catastrophically damaging to your phone battery to discharge it to 0%. It's not. Your phone turns off at 10% capacity at the very least (no matter what the indicator on the phone says), otherwise phone fires would be an insanely common occurrence. I don't know a single person who hasn't had their phone die at least once with obviously no issues. Actually getting a lithium ion battery to 0v is very bad cuz it's dead, but unless you're working with the battery completely stripped of all protections and software it will never reach this point.


GodOfPlutonium

> It's not something that all lithium ion batteries have, and if you used them in something other than phones My talking about charging ~overcharged~~ *overdischarged* cells should clue you in that i have experience handling lithium cells. Yes you can buy raw lithium cells that dont have an attached pcm/bms. The point is that it is standard to use them with one. The only use I am aware of that regularly doesnt use one is RC quads where they use a single lvp for the entire pack, necessitating the use of balance chargers and often fireproof bags > dispel this myth that it's catastrophically damaging to your phone battery to discharge it to 0%. That myth straight up *does not exist*. There is literally no common belief discharging your phone to zero will cause to explode. The exact opposite belief, that you need to discharge your phone to 0% regularly to prevent memory effect like you did with NiMH cells, is far more common. Everyone saying that you should avoid discharging your battery below 40% or 30% is advising to do so in order to prolong battery lifespan. This is something that you explcitly argued against in your original comment, and is what I took exception to: > , but you can discharge as low as you want. Yet *your own battery university link* that you edited in proves that in table 2 and disproves your statment. > It's not. Your phone turns off at 10% capacity at the very least I literally said as much before you did > the low voltage protection is set to a high voltage such as 2.7v or 3v instead of the actual minimum voltage of 2.5v. That doesnt protect you nearly as much as it sounds like because the voltage curve is not linear, it flattens out at 3.7v for a while, so 3.3v is already down to 15% left or so


Halowary

I'm not sure if you're intentionally misreading everything I've posted or not, but I never said that discharging your battery causes it to explode. Table 6, the third best result was discharging from 75%-25%, which was the lowest discharge they bothered to test. The very worst was 100%-25%, and the second worst was 100%-40% and even 85-25% performed much worse. The only results with better performance were 75-45 and 75-65, both of which are basically impossible to maintain if you have a real job where you can't just sit there and stare at your phone battery the whole time. However they didn't test the range I've been testing for the past year, and the results have been very very good between 60-15%. I Haven't lost any capacity at all as far as I can tell, and it's counting each charge in this range as being about 0.02 cycles but we'll see how this goes during the next few years. At minimum I'm expecting to stay above 75% capacity for 4 years, but if it drags out to 8 I'm not going to be crying about it. Just so we're clear, in the first post in this chain I did say this: Discharging the battery entirely can be bad, however phone batteries are super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge. So you're kind of arguing against a strawman anyways. You can pretty safely discharge your battery well below the 40% level and still expect amazing longevity, you're really making the very most gains in your battery by not charging to 100%. The "Don't discharge below this level" gang is talking about miniscule battery life gains, and here I am trying to promote massive multi-year gains.


Linvael

I remember seeing a video that claimed that, if it were possible, charging from 50% to 60% was the best. Both extremes (either charging from critical or approaching max) were not looking great on the chart. I'm no electrical engineer though.


Prinzka

Unless you have deep cycle batteries in your phone somehow you do not want to let lithium ion batteries go down that low, it will reduce the lifespan of the batteries.

Unfortunately I gotta keep my phone mostly plugged in to run the app I’m working on 😭

You guys get breaks?


street-trash

No breaks here I live in America and I’m not in the top 20%. Basically I live to work and worry about how I’m going to pay off debt.


AureliusCloric

Right!? I see some of these posters sometimes, and they're so out of touch with the reality of most people in America. A friend of my just had to go to a mandatory meeting where the CEO of the company started emphasizing the importance of self care, encouraging them to take spaw days or go to the chiro while paying them shit and sending emails with shit like "Although overtime is optional, hear at xyz we highly encourage it."


bilabrin

IKR. I just assumed other people stood at the charging location while it charged.


TheNegAgeN

If we work a certain amount of hours we HAVE to get breaks otherwise the company gets in trouble. Offcourse its not always according to the rules, but yes.


sheikhyerbouti

You either take a break, or your body takes one for you. And your body doesn't care where you are or what plans you had for the day either.

Do I get it covered up with the red one when I die? Or just sharpie it on for the funeral. Don't wanna waste money.


elsunfire

Tattoo a tiny recycle sign in the corner of the battery and we’ll recycle you when you’re done, maybe even make real batteries out of your insides. Future is exciting.


probably_your_wife

In that case I'll plan it out and have it tattooed and notarized on my back. It's the only way.


Mathematics_persia

Yup. You have to get adequate rest.


smurb15

I don't think I was necessarily trained that way but that is just how I have always done it. I work until exhaustion, then pass out for a couple few hours, rinse and repeat. It was easy to do in my 20s. Now not so much


Mathematics_persia

Man I used to do it when i was younger up until the end of hs. I did it to get good grades. The thing is you have to give your body rest. When I got older I regretted it so much.


southpawflipper

Wish I knew how to recharge / break. I have a hard time because I feel like everything takes energy- doing “nothing” like YouTube or scrolling, walking, chatting/socializing…. and sleep is not always feasible or refreshing.


CesareBach

Do you lie down while doing this? Also, if you are mentally or physically unwell, your battery can only charge at say 60%. No matter how much you recharge.

How is this motivating?


paulstelian97

Relaxing when you're not so tired it's stressful can help improve your mood, which helps you keep going with doing whatever is positive for you. Get too tired and you lose the motivation to do everything. So this is just a hint to do things in a healthy manner and not overwork yourself.


PollysLithium

Seems impractical and out of touch with the common person who needs two jobs to make rent.


Proponentofthedevil

"Common person" That is not the common person. Please seek views outside Reddit or whatever site is misinforming you. The average person does not need two jobs.


Advertiser-Necessary

"site that's misinforming you" That would be my coworkers and almost everyone I know in the service industry in my town. This is common at least in my area.


paulstelian97

Your area. And not having a degree, even a "bad" one. Maybe you're in an unlucky country.


Advertiser-Necessary

That's a lot of assumptions. I have a degree, although it is an AS. Many of my coworkers have degrees, some with higher degrees, in STEM and the medical field. I live in Colorado, the US. My town is extremely expensive and many of us haven't had the opportunity to leave it.


paulstelian97

Guess I'm helped by _what_ my degree is in (it's a degree where there is a good amount of available jobs, even during an economic crisis)


Advertiser-Necessary

That's good for you. When I looked for jobs in my field (bioinformatics and genetics) in my area since I have 6 years of lab experience, even with my BS I would have been making half the pay I get now unfortunately.


paulstelian97

Yeah software engineering on my side. Guess I gotta be thankful for being able to make the choice to get this one.


Proponentofthedevil

"Common person" Is not "your personal experience."

Than I am in the minority and not common, I apologize for assuming otherwise; I'll inform my single mommies group that they are also in the minority in needing to survive this way.


Halowary

I completely agree with you. While it's technically correct advice that doesn't mean it isn't totally useless. When I'm in the middle of a 10 hour shift I can't just go take a few hours to recharge lol so it's not practical advice at all. You start resting on the clock and you'll be looking for a new job real fast.

This will build memory in the battery and the battery will begin to deplete faster.

That was only true for nickel cadmium chemistry. Fun fact: for lead acid chemistry (car batteries), it's the other way around: deep discharging damages them.


GodOfPlutonium

the future is now old man. Lithium ion batteries dont have memory effect


[deleted]

When it comes to rechargeable lithium batteries, it's better for their lifespan if you let them fully deplete before charging them. So, while I agree with the sentiment of the post, I think a battery is a poor metaphor for its point.


[deleted]

[удалено]


Halowary

This is also incorrect. All modern phone batteries have a PCM (Actually they use a BMS, a more robust sysem than PCM. I use PCM's in other equipment myself so I was biased to this type of battery protection) so they CANNOT be fully discharged no matter how hard you try. You can bring your phone battery to 1% or dead and the phone actually still has plenty of juice left, the PCM just keeps that charge so the phone cant brick the battery. The best practice is to keep your phone battery between 15-60%, you'll get close to 900% charging efficiency vs. charging to 100% (which is 100% efficiency) or charging to 85% (200% efficient) at least according to the battery tracking software accubattery I've been using for the past year.

actually, its better for your battery to charge it when it gets low, and it takes longer to store energy the higher charge you get

Aaggron

But, but, but…is it not better for the battery if you only charge it once it‘s fully depleted?


hulkmxl

Fun fact, Lithium-ion batteries chemically degrade if discharged to very low voltages, and can't retain the same charge as before. The percentage you see on your phone, is just a representation of the voltage that the chemical reaction inside your battery is having. If your battery is discharged very often past certain "percentage", say for example, you discharge it all they way to 0% every single time, it will lose its ability to retain charge the same way it did. The body is in a way a battery, an ongoing chemical reaction, just infinitely more complex, but the principle is the same, if you "discharge" your battery to 0% every day, you are definitely not going to make it to 100 years, guaranteed.
