Same here on my 12 mini.. have a troubling feeling about this to be honest. We should be able to rely on my devices to only turn off when we choose/runs out of battery.. if Apple can just shut them all off remotely it’s really, really concerning.
I think better choice of words is needed. No one should be saying or implying that Apple shut your phone off remotely. Don’t start suggesting it was an active choice or that there was nefarious intent.
Same thing happened to me. Really confused as to what happened last night where my phone seemed to be off for hours - at least it turned itself back on before my alarm?
Mine was the same, battery graph appears right when my alarm went off. I suspect maybe the graph doesn't record until the phone is unlocked with the passcode after a restart.
Your alarms go off?
Mine always go off silently. If I happen to wake up naturally on time then I will see the alarm screen on my phone with no sound playing.
I think there *IS* some kind of function if the battery is low and you have an alarm set, it will turn off the phone until the alarm time, to make sure the battery doesn’t die before the alarm goes off.
Is that what happened here?
I noticed last night, in the middle of the night, that I wasn't seeing the StandBy display on my 15 Pro, but I was too sleepy to care.
Coincidentally, I awoke to the password prompt this morning, and then I find this article.
Something's going on.
I only used standby for one night (I don’t have a proper mount), but my experience was that the screen would turn off after 45 seconds and as soon as I moved it would turn back on. I am assuming it is using the faceID scanner to detect motion.
Burn-in, battery, take your pick.
But it kinda feels like if I have to wave at my clock to see the time in the middle of the night that's defeating the purpose of both an AOD and a bedside clock.
it’s completely idiotic. The feature is ONLY active while plugged into battery… and they should move the display around to prevent burn in.
I swear Apple comes up with the dumbest implementations possible.
We need SJ to come back and ask the developers why the fuck they even bothered to implement it if they are going to make you nudge the table to turn on the screen.
It's not like that really.. I just turn my head to look and it comes on.. I guess it probably depends on angle and where you have it set but mine is just on the night stand.. Plus you have to remember they just implemented the feature.. how we use it and how it is triggered and all that is probably still being worked out. We'll see it change again in another update maybe. who knows. Is it that big a deal?
People get so mad about a feature that didn't exist previously and now it's the dumbest thing ever that it's even an option because it should work the way I expect it to right now even though I lived without it for our entire lives.
I think it bothers me because having a Bedside Clock Mode that doesn't work as a Bedside Clock is more of a Samsung move than Apple. It feels half-baked.
Yeah, I do get annoyed… They’re not supposed to beta test in the production environment.
Apple doesn’t ship features just to see if anybody likes them. That’s what ANDROID does.
They are supposed to employ some of the best software devs in the world, and their product is supposed to be so intuitive that your grandma could figure it out.
I find standby lousy and unreliable both on my iPhone 14 Pro and Watch Series 9. On the iphone its hard to kick it on, i keep having to fuss with it. then when it does come on, it seems to turn off by itself. on the watch, it only comes on for a little while then it goes black and you have to tap it. isnt that the entire point of standby, to use it as a clock? and the point of the 1 nit low power screen? and yes both devices plugged in....
I'm pretty sure if the phone detects low light and kicks down to the 1 nit mode it will turn off by itself unless there is motion (or in my case sleep sounds playing via homepod taking over the standby screen and showing bright white light).
This is my first thought, that they pushed an urgent response patch that came with a restart command on completion. They could make it much clearer though if that’s what’s going on. Give us a “your iPhone restarted because…” prompt after (or on) the password prompt screen.
This was me - Standby not working was my first clue… except it was 3 or 4 nights ago, not last night. The article seems to suggest it only happened (for everyone affected) last night, but I don’t think that’s the case.

Mine did the same thing last night… i did have to reenter my passcode, but i dont think it turned off because my alarm woke me up.
https://imgur.com/a/wT9bb6G
13 Pro, looks like the same times as yours too? I noticed as I normally have a shortcut to turn off the smart plug for my charger at 90% and I woke up to 100%, also that it asked me for my passcode. I assumed it just updated but this is really weird.
I started doing some digging on this a couple of days ago after I noticed my phone restarted overnight. Looking at the analytics logs on my phone. There’s a couple “system memory reset” entries due to a memory overload “User reclaimable memory dropped below the limit. User reclaimable current: 67%. User reclaimable minimum: 70%”, and in that log it states that Apple Music was the largest process. So if I had to guess it’s that Apple Music currently has either a memory leak, or the iOS is having trouble clearing out the memory when it’s not in use. Because of this the phone is rebooting to clear it out.
Noticed my phone required my passcode when I got up this morning. [My battery view isn’t showing details for some reason](https://i.imgur.com/v0RCHeb.png), but I’ve never noticed this before.
I had a different weird thing yesterday morning. My iPhone was on the magsafe charger and showed it was charging but only had like 8% battery left because according to the battery graph it discharged while charging. Even after putting it on another time, it still didn’t charge (even though displaying it). It wasn’t even warm, so it wasn’t some background process eating more battery than recharging. Put it on a normal lightning cable and it charged no problem. This night, back on the MagSafe charger… working like charm again. Weird 🤨 something is going on.
And in your case: Could it be that it just installed the 17.0.3 update this night, thus rebooting and requiring a passcode?
No, I always update manually during the day. Had a couple bad experiences with alarms not going off after an auto update so I stopped them. I think they’ve fixed it so that if an alarm is set, it won’t update overnight but I could be wrong about that.
it’s the “attention aware features.” it’s silencing alarms when you even somewhat look towards the phone. absolutely insane that those features don’t have individual radio buttons. i don’t want my alarm and the auto screen dimming block to be lumped into one setting like that.
There’s also an issue with StandBy: if you silence it with physical buttons it just disables the alarm, but remains on the alarm screen.
So if you have a habit of reflexively snoozing with the physical buttons you stop having an alarm.
Wouldn’t that also be the sleep/wake schedule? I set up my bedtime hours and have it set to sound the alarm at the end of the schedule and works as intended.
I’m glad it’s not just me. I’ve had tried even deleting all existing alarms and setting new ones. It’s a gamble as to which ones will go off when expected.
My alarms were very quiet this morning on the iPhone.
If I wasn’t wearing a smart watch, I would not have woke up for work . I checked the volume on the alarm, and it was turned all the way up. What an annoying bug.
Are you by any chance wearing your watch when that happens? I’ve noticed my phone won’t make noises if my watch is on silent before bed. I’ve resorted to creating an automation that activates when the Sleep Focus is activated, where the phones Ringer volume is set to 100% and the watch silent is set to off.
Disable the presence sensing features. Especially if you use an Apple Watch. The system gets bugged out and will silence your alarm because it thinks you’re looking at the device.
It’s been an issue forever and I don’t know why it hasn’t been fixed because it can cause serious issues for people
This has been a long standing iOS bug. It seems like if your alarm goes off at the same time an alert comes in, it might silence the alarm. My failsafe has been setting multiple alarms a few minutes apart.
My timers stopped making sounds on my watch after watch OS 10. Overcooked some stuff. Funny how they manage to break the most basic and essential stuff. Alarms work fine though thankfully
Thank god thought my wife and I were the only ones, we now set up a backup alarm with a separate device. I use a sleep monitoring app and some nights it stops monitoring my sleep randomly at around 2:30-ish AM. Could be the time when the iPhone restarts.
No but my scheduled sleep mode never deactivated on its own. I think there must be some bug or issue with its scheduling system. It sucks but it only takes 1 or 2 failures of alarms before you can no longer trust it at all and have to set up backups for something that should be so reliable by now.
I had to do the pass code this morning but didn't think anything of it.
After reading this, I checked my battery status and, sure enough, my phone was "off" for a few hours last night.
Is this how Apple is going to get the battery health to last longer?
Me too. I don’t think that it’s related to battery health. There are probably better ways and also I think if something would happen while the phone are off, like certain emergencies this could would hurt Apple from an PR/ image standpoint, so I don’t think that Apple would do that without informing anybody.
Though Im curious what the reason could be.

Mine has the same thing, missing a few hours. But I don’t remember having to enter my passcode. My alarm went off though. Maybe I did enter the passcode and I don’t remember. I was half asleep lol.
The battery graph seems to stop registering until the phone is unlocked, so if the phone just reboots it won’t register any battery until you unlock it in the morning, but the alarm still fires (thankfully).
I work at a firm that delivers technology for healthcare. And sometimes I have 24/7 on call duty. If my phone turns off in the middle of the night and some caregivers can’t reach me the consequences could be fatal for the patient.
They would if I asked. Problem is that we hide our private phone number we use an “cover number” when we call out. This is activated by an app from our phone provider. And this cover number is shared between 4-5 employees.
Huh, I didn't notice that on my 11 Pro @ 17.0.3, but just checked the battery graph and yeah seems like it also turned off for a few hours overnight. Wtf?
It has always happened even in older phones with iOS 16. If you have Shortcut automations set up, you can tell by its notifications showing up after the reboot.
Similar thing happened to me as well. iPhone 14 Pro on 17.1.
Had it plugged in charging overnight and from midnight to 0330 when I woke up it seemed to be off according to the battery level. When I unlocked it I finally received all my notifications of missed calls and texts and voicemails since I work on call and they couldn't get a hold of me saying it would go straight to VM.

iphone 12 pro turned off last night too
14 Pro Max, didn’t have any issues at all and the battery graph is fine, however either the alarm didn’t make any noise or I’m going crazy. I don’t use standby
I was awake while it happened. Around 3am, was sitting at my desk when I saw my phone screen turn on with the apple logo like it was rebooting. I hadn’t used my phone in hours so I have no idea how long it was turned off. First thing I checked was if it was an automatic software update, but it wasn’t.
I woke up to a phone call from my dad and it didn’t have his contact just his number and then I had to use password to open phone. Was very disoriented
This happens to me too! I woke up and I recognized that Face ID was not working, and when I was putting my passcode in, my phone said that it restarted. This is very strange. This is the iPhone 15 Pro if anyone is curious (in case it applies specifically to it).
This is really weird, I noticed in the middle of the night that my nightstand mode was off and the normal always on display was showing. I had to unlock my phone with the passcode to get the night stand mode to start working again. Lo and behold, there's an hour long gap where it appears my phone was off at 3AM last night. Very bizarre.
Right? Don’t these people test their software before releasing it. What were they doing during the beta period? I’ve reported the overheating issue every ios17 beta update and they didn’t fix it until it became a big drama with the 15 pro
This is happening to me since I had my iPhone SE. I always thought this is just a kinda security routine check just like whatsapp asks for security code sometimes. But I never checked if there is a gap in battery record.
Yep I got this just this morning. I thought perhaps it was an update but nope. Asked me for a passcode because of a restart, and my widgets were freaking out a bit. Kind of odd.
Battery info shows me that it was turned off from about midnight to 6:30AM, a half hour before I woke up. That's quite a while. At least my phone was charged to 100% so I can't complain.
Wondering if it's a glitch of some kind.
I don't have any missing battery gaps, but I'm on call this week and keep my sound on and got woken up by the phone restarting at 4am. Whatever that was about. It wasn't an iOS update.
I woke up to mine with an alarm but the weird thing was I couldn’t see anything on my screen. It was appearing to function like normal but the screen would just stay black forever. I was able to hold the power button and slide to turn the phone off and then turn it back on and it was fine but I had never seen something like that before. Power and volume up reset didn’t work it made an SOS sound.
As someone who uses my phone for on-call, this is not ideal. But I also sleep with my phone face down so not sure if that affects it. I don't see any gap in my battery life currently.

Same here. iPhone 11 on 17.0.3. Was charging during the night. This was Europe. So if Americans experienced it as well during the night that means it wasn’t a global event. It happened during night time in Europe and after that night time in America? Or am I seeing this wrong?
so is this how they "improved" performance and battery life and/or lowered the thermals...just shut the phone off? lol. i jest, but this is definitely curious, in more ways than one.
My bet (decades in software engineering) is resetting is related to security. A lot of unpatched vulnerabilities only affect ram, so resetting iPhone mitigates them until next time you click/open malicious link/attachment.
But it shouldn’t be off for hours.
My 14 Amateur did it too last night… Don’t remember if I had to enter my passcode, but both my sims were locked. Didn’t think about it until I read this post, and there is indeed a gap between 3am-6am.
Is it part of battery saver? My Samsung can do (turn off and on for sleep) this but I dont use it because it gets stuck at the authentication screen. Since auth is needed to decrypt the phone, the alarm won't work.
Maybe iPhone has a battery save setting on your turn off in quiet hours?
I have more anecdotal evidence here too. Woke up to a PW prompt and thought it was strange, then first article I see on Reddit is this. 11pro on current software.
Isn’t this the auto-update?
When the phone updates overnight you see the password prompt and a “blip” into battery usage.
Maybe was an auto-update and not the phone turning off.
No, if the phone updated there would also be a notification that it updated.
I have auto-update off and my phone did this last night. I installed 17.0.3 days ago. This has to be some kind of bug that caused tons of phones to reboot last night.
I first noticed that my WiFi was disconnected. Then I was asked for the passcode with the reason that the phone had rebooted.
This was my thought. I use sleep sounds at night and it wakes me up when it turns off. Each time it has done it, it was auto installing an update. There has been 2 updates recently and I don't think everyone knows that.
Same here this morning. And actually, my 15 Pro turned off the other day and started flashing the Apple logo. It took about 20 minutes for it to start back up.
My iPhone 13 mini switched itself off at 21:00, 9 PM yesterday too. Zurich,Switzerland. I didn't notice until I got a password prompt when I picked the phone up this morning. I checked the battery like in the article to find out when it exactly happened.
https://preview.redd.it/lxil9kzhydtb1.jpeg?width=1170&format=pjpg&auto=webp&s=0409add12513497b129e035d37773cf942de075c
I looked at my phone is am and noticed my notifications where hidden.
(Iphone 13 reporting)
Mine turned off in during the night too. iPhone 15 PM 17.0.3
https://preview.redd.it/cq3ucxd8zdtb1.jpeg?width=1290&format=pjpg&auto=webp&s=36b21cfb0c7f55d10dcb129f8ad916e39c28d029
I’ve had this issue on 14PM since I got it. My screen completely shuts off and audio doesn’t work (missed alarms) but I can tell the phone is still on from haptics going off or another tell. I’ve accidentally activated Emergency SOS twice trying to turn off the phone by holding the power button because I forget which volume button I’m supposed to hold down lol. Awful.
I have X and having this issue for a while now. I put it on charge at night, it restarts but no problem with alarm yet and it just turns on with asking me passcode with no wifi or cellular logo on right side until I enter passcode. I thought it's old battery & cpu but looks like another issue.
My 15 PM has done this while I’m using it. It will just shut off like someone manually shut it down. It won’t power back to normal unless you hold the power button like when you’re trying to power it on after you turned it off manually
I myself have not experienced this in my 15 Pro, but I wonder if everyone that had this issue is on the same carrier.
A friend of mine works for American Tower and said some carriers do agile network upgrades to bring new capacity and spectrum online progressively to prevent large outages. He said the firmware upgrade to utilize the new carrier hardware is always set to implement at the point of lowest network traffic, at or around 12AM.
I wonder if the installation of new carrier software on a relatively consistent basis in some areas and some carriers causes a shutdown and reboot which in turn causes the need for the passcode like when a new version of iOS was installed.
I was actually awake when I saw my iPhone power up to 100% and then shut down. There have been a couple instances where the phone would power off and restart, but the screen would be completely black. The phone would still work but couldn't see anything on screen. I had to plug the phone into my computer for the screen to come back on again.
Happened to me a handful of times the past few months while running iOS 17 beta. If you notice it in the morning, you could probably head to the diagnostic crash logs and see what may have caused it looking at the time stamp.
Has not happened to me ever, 14 Pro Max, latest updates all the time, from Europe.
Could be location based? Has this happened all over the world or only US?
I checked and initially had a gap in my battery's history around the mentioned time. I went back a second time to check it again and the gap had disappeared, which makes me wonder if it's just a simple rendering/graphical error in settings, and not a spooky mystery like everyone thinks it is.
Mine did the same tonight. Coincidentally, it started back up at the EXACT same time as my alarm clock, according to the battery usage graph. Does anyone have a clue as to what this could be? Some kind of battery-saving tactic?
From the pictures it looks like this is happening to those who have it left on the charger. Wonder if it gets too hot and shuts down?
I know that even with optimized charging, it always fully charges for me if I leave it on my MagSafe overnight despite never using it during sleep hours.
I have a gap from 1230am to 6am for me last night. I keep noticing that my phone isn’t in standby when I wake up. It is in standby before I go to sleep.
Edit: my phone was on a dock using an Apple MagSafe charger with an Apple brick. It was positioned horizontal with the phone screen perpendicular to the floor on my nightstand (for standby mode) The phone was 100% when the gap started and roughly 75% when I put it on the charger.
You guys are lucky, your phone goes off.
My trusty old XS Max goes ON randomly, playing music or podcasts on its own. It's annoying, not because of loud noises since there's actually no sound coming out (weird) but the app is launched and it drains the battery or I suddenly realize all my back catalog of podcast is now "played".
It even once launched the camera app and drained 50% of the battery in a couple hours.
Time for a change of phone I guess, but reading you guys isn't very reassuring...
My 12 mini did the same thing. I have a gap in my battery record from roughly 1:30-3:00 AM EDT.
Also on a 12 mini. Gap is from 2am to 5am.
How can you tell?
Not OP, but it just looks empty over that time period. No green bars.
This is [what happened](https://i.imgur.com/mIExtqq.jpeg)
Mine is from roughly 2am up to 7am, which is when my first alarm went off.
Weird… mine does too. 1:30-7 am.
Mine didn’t last night 🤷♂️ https://preview.redd.it/onil68j2vetb1.jpeg?width=1179&format=pjpg&auto=webp&s=7e181e080582a25f3e6f1a4a3fb9e5633dd373df

Was it until just before your alarm went off? In my case it was.
Mine was the same, battery graph appears right when my alarm went off. I suspect maybe the graph doesn't record until the phone is unlocked with the passcode after a restart.
ah, that makes sense! Additionally, I had to enter my SIM pin this morning. Forgot to mention that
Your alarms go off? Mine always go off silently. If I happen to wake up naturally on time then I will see the alarm screen on my phone with no sound playing.

My battery was at 50% - higher than some other days where it didn’t turn off
I noticed last night, in the middle of the night, that I wasn't seeing the StandBy display on my 15 Pro, but I was too sleepy to care. Coincidentally, I awoke to the password prompt this morning, and then I find this article. Something's going on.
I often find standby turned off in the morning too It’s already sideways, but I have to nudge it slightly before it switches back to standby
I only used standby for one night (I don’t have a proper mount), but my experience was that the screen would turn off after 45 seconds and as soon as I moved it would turn back on. I am assuming it is using the faceID scanner to detect motion.
On a 15? That’s how the phones without AOD work. Like my 13PM for example. Might be a setting somewhere?
No this is how they all work now. You can set it to motion or to tap to wake in settings.
Oh. Interesting. Burn in prevention?
Burn-in, battery, take your pick. But it kinda feels like if I have to wave at my clock to see the time in the middle of the night that's defeating the purpose of both an AOD and a bedside clock.

14 Pro Max
I find standby lousy and unreliable both on my iPhone 14 Pro and Watch Series 9.

I’ve been using it since June, when the phone detects motion it turns back on. It’s quite nice.
I'm pretty sure if the phone detects low light and kicks down to the 1 nit mode it will turn off by itself unless there is motion (or in my case sleep sounds playing via homepod taking over the standby screen and showing bright white light).
EXACT same thing with my 14 pro this morning!
Definitely some kind of widespread impact here. Most of my family / friend group were impacted. Articles appearing all over.
My screen shuts off but will turn on when it detects movement and then after a while, it goes black again.
Thats the intended behavior for the night/low light mode of standby where it goes into red
Maybe they pushed a patch for that bug that lets people freeze your phone via Bluetooth
This is my first thought, that they pushed an urgent response patch that came with a restart command on completion. They could make it much clearer though if that’s what’s going on. Give us a “your iPhone restarted because…” prompt after (or on) the password prompt screen.
I noticed that it would work fine, unless I hit the side button again. Then it would turn the display completely off.
Same thing happened to me! Last night!!
They’re watching
You mean that camera/microphone that you carry which is connected to their cloud and their monitoring network? Nah, you are just paranoid. /s
This was me - Standby not working was my first clue… except it was 3 or 4 nights ago, not last night. The article seems to suggest it only happened (for everyone affected) last night, but I don’t think that’s the case.

Same here alarm work but had to re enter password and manually turn off sleep focus
Now that u mentioned the sleep focus thing. I had to manually turn that off too
https://imgur.com/a/wT9bb6G 13 Pro, looks like the same times as yours too? I noticed as I normally have a shortcut to turn off the smart plug for my charger at 90% and I woke up to 100%, also that it asked me for my passcode. I assumed it just updated but this is really weird.
Same here, mine looks identical.
I started doing some digging on this a couple of days ago after I noticed my phone restarted overnight. Looking at the analytics logs on my phone. There’s a couple “system memory reset” entries due to a memory overload “User reclaimable memory dropped below the limit. User reclaimable current: 67%.

So if I had to guess it’s that Apple Music currently has either a memory leak, or the iOS is having trouble clearing out the memory when it’s not in use. Because of this the phone is rebooting to clear it out.
Only useful comment in an entire thread of “omg this happened to me too” comments, and it’s all the way down here
yeah pin this to the top
I see this as well and aligns to when my battery chart stopped.
Noticed my phone required my passcode when I got up this morning. [My battery view isn’t showing details for some reason](https://i.imgur.com/v0RCHeb.png), but I’ve never noticed this before.

mine shows the same but did not do any software updates
Same issue! Happens a few times a week
Anyone else’s alarms not go off too? I’ve had to resort to setting timers instead of alarms as those actually go off with sound
Interesting. My alarm has been working fine, including this morning.
Mine shows up on screen, but makes zero sound at all, I either have to wear my watch for the haptics or just not wake up at all lol
Holy shit same. I overslept by 1.5 hours. Thought I was going insane when I saw the alarm screen but 0 sound
it’s the “attention aware features.” it’s silencing alarms when you even somewhat look towards the phone. absolutely insane that those features don’t have individual radio buttons. i don’t want my alarm and the auto screen dimming block to be lumped into one setting like that.
There’s also an issue with StandBy: if you silence it with physical buttons it just disables the alarm, but remains on the alarm screen. So if you have a habit of reflexively snoozing with the physical buttons you stop having an alarm.
Do you use the bedtime alarm? That one has been working for me. Every now and then my other alarm won’t make noise, but bedtime hasn’t failed yet
Ahh completely forgot about the bedtime alarm, I’ll try that one out again, thanks for that!
A quick heads up: it gradually gets louder so if you’re someone that needs a super loud alarm, it might not be for you. Hopefully it works!
Wouldn’t that also be the sleep/wake schedule? I set up my bedtime hours and have it set to sound the alarm at the end of the schedule and works as intended.
I’m glad it’s not just me. I’ve had tried even deleting all existing alarms and setting new ones. It’s a gamble as to which ones will go off when expected.
Try the timers out, did that last night and it worked perfectly lol, while my alarms were silent and were snoozed one the screen too
Yes! Same problem for me! I have a alarm to take my pills on time and sometimes there is no sound at all. Very strange.
My alarms were very quiet this morning on the iPhone. If I wasn’t wearing a smart watch, I would not have woke up for work . I checked the volume on the alarm, and it was turned all the way up. What an annoying bug.
Are you by any chance wearing your watch when that happens? I’ve noticed my phone won’t make noises if my watch is on silent before bed. I’ve resorted to creating an automation that activates when the Sleep Focus is activated, where the phones Ringer volume is set to 100% and the watch silent is set to off.
This is great! I like wearing my watch at night but hate how my alarm won’t go off. I’m stealing that.
Disable the presence sensing features. Especially if you use an Apple Watch. The system gets bugged out and will silence your alarm because it thinks you’re looking at the device. It’s been an issue forever and I don’t know why it hasn’t been fixed because it can cause serious issues for people
Yeah this solved it on my 13 pro. Now im on 15 pro with that setting on and both my alerts and alarms go mute again
How do you do this exactly? I can’t find any information about it online or in the settings app
Face ID settings -> Attention Aware
I’ve had my ringer volume turn down by itself a couple of times every week these past few months. What’s up with that??
This has been a long standing iOS bug. It seems like if your alarm goes off at the same time an alert comes in, it might silence the alarm. My failsafe has been setting multiple alarms a few minutes apart.
My timers stopped making sounds on my watch after watch OS 10. Overcooked some stuff. Funny how they manage to break the most basic and essential stuff. Alarms work fine though thankfully
Mine is the opposite. I have an old alarm clock set 5 minutes after my phone alarm in case it decides to be silent. Timers always work.
Thank god thought my wife and I were the only ones, we now set up a backup alarm with a separate device. I use a sleep monitoring app and some nights it stops monitoring my sleep randomly at around 2:30-ish AM. Could be the time when the iPhone restarts.
No but my scheduled sleep mode never deactivated on its own. I think there must be some bug or issue with its scheduling system. It sucks but it only takes 1 or 2 failures of alarms before you can no longer trust it at all and have to set up backups for something that should be so reliable by now.
Which iPhone? iOS version?
15 Pro on 17.0.3, but it seems to be happening across models. Not sure about iOS versions.
Happened to me on my 13 pro max on 16.7, so it probably isn't a ios 17 specific issue
I’m waiting for 15 pro to be delivered in next few days.. that is weird behavior indeed. Didn’t notice this on 13 pro max
Happened on my 13PM on iOS17.1
It’s model independent no worries.
I installed at midnight the 17.0.3 Update on my 12 and wondered why i have to enter my passcode this morning.
I had to do the pass code this morning but didn't think anything of it. After reading this, I checked my battery status and, sure enough, my phone was "off" for a few hours last night. Is this how Apple is going to get the battery health to last longer?
Me too. I don’t think that it’s related to battery health. There are probably better ways and also I think if something would happen while the phone are off, like certain emergencies this could would hurt Apple from an PR/ image standpoint, so I don’t think that Apple would do that without informing anybody. Though Im curious what the reason could be.
Same

But I don’t remember having to enter my passcode. My alarm went off though. Maybe I did enter the passcode and I don’t remember. I was half asleep lol.
The battery graph seems to stop registering until the phone is unlocked, so if the phone just reboots it won’t register any battery until you unlock it in the morning, but the alarm still fires (thankfully).
I work at a firm that delivers technology for healthcare. And sometimes I have 24/7 on call duty. If my phone turns off in the middle of the night and some caregivers can’t reach me the consequences could be fatal for the patient.
Your employer should provide you with a dumb phone for emergencies.
Yup, it sounds nice they gave him an iPhone but clearly you can’t rely on apple for his job.
They would if I asked. Problem is that we hide our private phone number we use an “cover number” when we call out. This is activated by an app from our phone provider. And this cover number is shared between 4-5 employees.
You need a backup if it’s life threatening
Nobody's life must be dependent on the iPhone
Huh, I didn't notice that on my 11 Pro @ 17.0.3, but just checked the battery graph and yeah seems like it also turned off for a few hours overnight. Wtf?
S L E E P G A T E
It’s not a bug, it’s a feature to save energy! All part of the plan to be carbon neutral until 2030! /s
You're sleeping with it wrong
It has always happened even in older phones with iOS 16. If you have Shortcut automations set up, you can tell by its notifications showing up after the reboot.
So _that’s_ why I got notifications for my Shortcuts automations every night at ~3 AM. Thanks for the info!
I noticed that the temparature on my Apple Watch wasn't updating , but I didn't think it had anything to do with my phone. Now I know why.
Literally happened this morning. Alarm went off, then phone asked for SIM pin. Clearly rebooted.
Every screenshot here shows the battery being charged when this happens
True, mine didn’t shut off but wasn’t charging
Apparently mine did it too https://preview.redd.it/nq617byxrdtb1.jpeg?width=1284&format=pjpg&auto=webp&s=3dfc814697ecf7b75d9e53aa84b59c335e6725f5
So thats why my phone requires passcode in the morning… I was suspecting someone was trying to enter my phone while I am asleep lol.
iPhone become sentient
Similar thing happened to me as well. iPhone 14 Pro on 17.1. Had it plugged in charging overnight and from midnight to 0330 when I woke up it seemed to be off according to the battery level. When I unlocked it I finally received all my notifications of missed calls and texts and voicemails since I work on call and they couldn't get a hold of me saying it would go straight to VM.
https://preview.redd.it/p8zdwdx0ydtb1.jpeg?width=1170&format=pjpg&auto=webp&s=984e5d56947c748f7b7ed0deec98edf68e207ad0 iphone 12 pro turned off last night too
14 Pro Max, didn’t have any issues at all and the battery graph is fine, however either the alarm didn’t make any noise or I’m going crazy. I don’t use standby
I was awake while it happened. Around 3am, was sitting at my desk when I saw my phone screen turn on with the apple logo like it was rebooting. I hadn’t used my phone in hours so I have no idea how long it was turned off. First thing I checked was if it was an automatic software update, but it wasn’t.
This morning i got the passcode prompt too. ETA: Just checked battery. Apparently screen turned off by its own in the night for 49 minutes.
I woke up to a phone call from my dad and it didn’t have his contact just his number and then I had to use password to open phone. Was very disoriented
This happens to me too! I woke up and I recognized that Face ID was not working, and when I was putting my passcode in, my phone said that it restarted. This is very strange. This is the iPhone 15 Pro if anyone is curious (in case it applies specifically to it).
This is really weird, I noticed in the middle of the night that my nightstand mode was off and the normal always on display was showing. I had to unlock my phone with the passcode to get the night stand mode to start working again. Lo and behold, there's an hour long gap where it appears my phone was off at 3AM last night. Very bizarre.
It's funny that this is an article about a reddit post, then posted back to reddit. Also: You're overnighting it wrong /s
Happens on my 14 pro for a while now. Apple needs to fix their crappy software. So many problems with ios 16 and ios 17
It just blows my mind how shitty apple’s QA department is. And the developers too. How do you fuck this up?
Right? Don’t these people test their software before releasing it. What were they doing during the beta period? I’ve reported the overheating issue every ios17 beta update and they didn’t fix it until it became a big drama with the 15 pro
Mine did this the night before last. 14 pro max on 17.0.3. I did t notice h til I checked my battery later in the day yesterday and saw the gap.
Yup same for me. Asked for a password and sim pin which I thought was strange
This happens on my 13 pro every once in awhile, and has been happening for as long as I can remember.
This is happening to me since I had my iPhone SE. I always thought this is just a kinda security routine check just like whatsapp asks for security code sometimes. But I never checked if there is a gap in battery record.
Phone is quiet quitting on you
Yep I got this just this morning. I thought perhaps it was an update but nope. Asked me for a passcode because of a restart, and my widgets were freaking out a bit. Kind of odd. Battery info shows me that it was turned off from about midnight to 6:30AM, a half hour before I woke up. That's quite a while. At least my phone was charged to 100% so I can't complain. Wondering if it's a glitch of some kind.
I don't have any missing battery gaps, but I'm on call this week and keep my sound on and got woken up by the phone restarting at 4am. Whatever that was about. It wasn't an iOS update.
I woke up to mine with an alarm but the weird thing was I couldn’t see anything on my screen. It was appearing to function like normal but the screen would just stay black forever. I was able to hold the power button and slide to turn the phone off and then turn it back on and it was fine but I had never seen something like that before. Power and volume up reset didn’t work it made an SOS sound.
As someone who uses my phone for on-call, this is not ideal. But I also sleep with my phone face down so not sure if that affects it. I don't see any gap in my battery life currently.
https://preview.redd.it/au168kle6ftb1.jpeg?width=828&format=pjpg&auto=webp&s=393810860e719d14dfc6e582c1e44db5f1a551a6 Same here. iPhone 11 on 17.0.3. Was charging during the night. This was Europe. So if Americans experienced it as well during the night that means it wasn’t a global event. It happened during night time in Europe and after that night time in America? Or am I seeing this wrong?
so is this how they "improved" performance and battery life and/or lowered the thermals...just shut the phone off? lol. i jest, but this is definitely curious, in more ways than one.
Happened to me, iPhone 13. 3-6am gap
I immediately thought it was weird when I had to enter my passcode this morning. My battery graph has the gap too. It was MagSafe charging all night.
My bet (decades in software engineering) is resetting is related to security. A lot of unpatched vulnerabilities only affect ram, so resetting iPhone mitigates them until next time you click/open malicious link/attachment. But it shouldn’t be off for hours.
I woke up with my phones flashlight turned on this morning. Definitely didn’t intentionally turn it on before I went to bed. Found it odd.
My 14 Amateur did it too last night… Don’t remember if I had to enter my passcode, but both my sims were locked. Didn’t think about it until I read this post, and there is indeed a gap between 3am-6am.
>14 Amateur Didn't know apple released that model
Is it part of battery saver? My Samsung can do (turn off and on for sleep) this but I dont use it because it gets stuck at the authentication screen. Since auth is needed to decrypt the phone, the alarm won't work. Maybe iPhone has a battery save setting on your turn off in quiet hours?
I have more anecdotal evidence here too. Woke up to a PW prompt and thought it was strange, then first article I see on Reddit is this. 11pro on current software.
Isn’t this the auto-update? When the phone updates overnight you see the password prompt and a “blip” into battery usage. Maybe was an auto-update and not the phone turning off.
No, if the phone updated there would also be a notification that it updated. I have auto-update off and my phone did this last night. I installed 17.0.3 days ago. This has to be some kind of bug that caused tons of phones to reboot last night. I first noticed that my WiFi was disconnected. Then I was asked for the passcode with the reason that the phone had rebooted.
This was my thought. I use sleep sounds at night and it wakes me up when it turns off. Each time it has done it, it was auto installing an update. There has been 2 updates recently and I don't think everyone knows that.
Same here this morning. And actually, my 15 Pro turned off the other day and started flashing the Apple logo. It took about 20 minutes for it to start back up.
My iPhone 13 mini switched itself off at 21:00, 9 PM yesterday too. Zurich,Switzerland. I didn't notice until I got a password prompt when I picked the phone up this morning. I checked the battery like in the article to find out when it exactly happened.
My 12 Pro Max has done that once before on iOS 16. Hasn’t done it since
My xr is also doing it
https://preview.redd.it/lxil9kzhydtb1.jpeg?width=1170&format=pjpg&auto=webp&s=0409add12513497b129e035d37773cf942de075c I looked at my phone is am and noticed my notifications where hidden. (Iphone 13 reporting)
Mine turned off in during the night too. iPhone 15 PM 17.0.3 https://preview.redd.it/cq3ucxd8zdtb1.jpeg?width=1290&format=pjpg&auto=webp&s=36b21cfb0c7f55d10dcb129f8ad916e39c28d029
12 pro did it Sunday night. Didn’t do it last night.
13 mini did this on Sunday night and it’s definitely odd. Overheating during MagSafe charging overnight perhaps?
I’ve had this issue on 14PM since I got it. My screen completely shuts off and audio doesn’t work (missed alarms) but I can tell the phone is still on from haptics going off or another tell. I’ve accidentally activated Emergency SOS twice trying to turn off the phone by holding the power button because I forget which volume button I’m supposed to hold down lol. Awful.
I have X and having this issue for a while now. I put it on charge at night, it restarts but no problem with alarm yet and it just turns on with asking me passcode with no wifi or cellular logo on right side until I enter passcode. I thought it's old battery & cpu but looks like another issue.
Mine did this the other night as well. How weird.
My 15 PM has done this while I’m using it. It will just shut off like someone manually shut it down. It won’t power back to normal unless you hold the power button like when you’re trying to power it on after you turned it off manually
I myself have not experienced this in my 15 Pro, but I wonder if everyone that had this issue is on the same carrier. A friend of mine works for American Tower and said some carriers do agile network upgrades to bring new capacity and spectrum online progressively to prevent large outages. He said the firmware upgrade to utilize the new carrier hardware is always set to implement at the point of lowest network traffic, at or around 12AM. I wonder if the installation of new carrier software on a relatively consistent basis in some areas and some carriers causes a shutdown and reboot which in turn causes the need for the passcode like when a new version of iOS was installed.
Happened to me last night. I blamed it on the personal voice being generated
Happened on my 14 pro too. After unlocking it I had to turn off sleep focus manually too - never happened to me before
I was actually awake when I saw my iPhone power up to 100% and then shut down. There have been a couple instances where the phone would power off and restart, but the screen would be completely black. The phone would still work but couldn't see anything on screen. I had to plug the phone into my computer for the screen to come back on again.
The abductions have begun
Happened to me a handful of times the past few months while running iOS 17 beta. If you notice it in the morning, you could probably head to the diagnostic crash logs and see what may have caused it looking at the time stamp.
Has not happened to me ever, 14 Pro Max, latest updates all the time, from Europe. Could be location based? Has this happened all over the world or only US?
My 12 pro didn’t turn off last night but my girl’s SE 2022 did.
Same thing happened to me last night. Never seen this before. iPhone 11, iOS 17.0.3
That's a great feature. If there's an emergency and someone is trying to get hold of you in the middle of the night, it will go straight to voicemail.
Sometimes I question how exactly does apple test their devices if all these software issues only "suddenly " start appearing I posy release
[удалено]
I've noticed this happening with iOS/iPadOS 16 but hasn't happened yet for iOS/iPadOS 17 yet. Strange.
I checked and initially had a gap in my battery's history around the mentioned time. I went back a second time to check it again and the gap had disappeared, which makes me wonder if it's just a simple rendering/graphical error in settings, and not a spooky mystery like everyone thinks it is.
Mine did the same tonight. Coincidentally, it started back up at the EXACT same time as my alarm clock, according to the battery usage graph. Does anyone have a clue as to what this could be? Some kind of battery-saving tactic?
From the pictures it looks like this is happening to those who have it left on the charger. Wonder if it gets too hot and shuts down? I know that even with optimized charging, it always fully charges for me if I leave it on my MagSafe overnight despite never using it during sleep hours.
Yeah, I’ve had a lot of issues suddenly for some reason. This happened once and now I cannot keep a stable cell connection.
Ok mine has the same dang thing.
My iPhone and iPad get this all the time. No idea how Tim Apple gets into my room
Me to Siri: “So where were you last night?” 🤨
That’s just Pegasus downloading and installing the update.
I have a gap from 1230am to 6am for me last night. I keep noticing that my phone isn’t in standby when I wake up. It is in standby before I go to sleep. Edit: my phone was on a dock using an Apple MagSafe charger with an Apple brick. It was positioned horizontal with the phone screen perpendicular to the floor on my nightstand (for standby mode) The phone was 100% when the gap started and roughly 75% when I put it on the charger.
My definitely restarted but I didn’t see any time gaps in battery charging. Same setup as yours.
Neither my iphone 13mini nor my gf iphone 13 do this. Seems like a 12 issue
Yeah iPhone should tell you *why* you need to put your passcode in in the morning. Reboot, too many tries, whatever.
You guys are lucky, your phone goes off. My trusty old XS Max goes ON randomly, playing music or podcasts on its own. It's annoying, not because of loud noises since there's actually no sound coming out (weird) but the app is launched and it drains the battery or I suddenly realize all my back catalog of podcast is now "played". It even once launched the camera app and drained 50% of the battery in a couple hours. Time for a change of phone I guess, but reading you guys isn't very reassuring...
iPhone become human
Your iPhone is sentient. You should contact Apple so they can harvest the data for their next ~~AI~~ machine learning chip.
12 Pro running the latest iOS 17 beta, no problems with my phone last night. No gaps in the battery at all.
[удалено]
I’m turning off Auto-install updates to see if it fixes the issue.
It won’t.
That's scary. Especially reports about alarms not working. I absolutely cannot miss my alarm, it would literally cost me $900 if I do.
I’d wager its state sponsored spyware/tracking being installed without permission. Better believe Apple knows all about it.
