Some iPhone Models Mysteriously Shutting Off at Night

Yesterday morning I woke up 15 minutes late for work and was confused my alarm had not gone off. I grabbed my phone and the alarm was in the dynamic island with no sound for 5:00am. It was 5:15am. I swiped up and nothing. The display did some strange stuff, zoomed in, but wouldn’t let me navigate. Accessibility is turned off. Tried a hard reset & nothing, the phone was acting like it had a stroke. Plugged it into a computer and put it into recovery mode. Then, while plugged in, I had did a hard reset and it worked. Super weird. Screenshot of analytics and apple support occurred later in the day. Diagnostics came back clean as it is clearly a software issue. System stability good too.

Using an iPhone 15 Pro Max lots of storage room and latest ‘stable’ release of 17.0.3. I don’t technically count anything stable until 17.2 though.

The other apple website posted an article the same day this happened. Those people that read it could check their charging info if it happened to them. I had a notification from shortcuts in the morning about enabled automations which displays after a reboot but did not think much about it. When I found out that it happened to other people it was too late because battery charging info goes back only like 20 hours.
 
It has to reboot after installing the monitoring software. Perfectly normal, nothing to see here!

The delay is because the monitoring servers were overloaded, it should have been rolled out sequentially. The monitoring software cannot boot without server access.
 
This isn't true because Cook can do no wrong as long as Apple is raking in the profits. Remember, the only thing that matters is that Apple is the world's most valuable company. Forget innovation. That and iOS has never been less buggy than it is today. It's fine...everything's fine. /s

Had this happen with my iPad Pro a while back. It would ask for passcode because it said it had restarted and looking at battery info it would show that it was turned off during the night when I was sleeping.

Took it to the Apple Store and they replaced it as faulty. They said that Kernel Panics were the issue. This was happening on iOS 15 and iOS 16. I explained that I had tried updating and even resetting my iPad but the issue persisted.

If you’re having this problem then I suggest going to Settings > Privacy > Analytics & Inprovements > Analytics Data and then searching logs for “panic”. You can also search by date.

That’s what Apple did and that was enough for them to give me a replacement iPad there and then. Who knows maybe it’s not the exact same issue. My impression was with my iPad that it was a faulty M1 processor but maybe this time it’s a software bug. But it isn’t affecting everyone so maybe it’s a problem with some A17 Pros?

It’s a good idea, but if you are having kernel panics, it’s not the same issue here.

This only happens overnight even if the phones are on a charger all day, and there are no logged events when it happens.

I wonder, did the phones actually turn off or did the battery stop supplying it's charge level? Most I see are of people charging the device when it happens. This could mean the battery wasn't charging during the "off" time, but the phone was still powered on. (running on usb/lightning power instead of battery power; so the battery was off, but not the phone)

Users are required to enter their pins to unlock the phone, suggesting a reboot.

There appears to be a curious phenomenon that is causing some iPhone models to turn off temporarily at night, which can interrupt alarms and other iPhone features.

In a thread on Reddit, a user complains that two separate iPhone alarms in his home failed to go off. Several other users also chimed in with similar issues, and it turns out that some of the issues could be linked to the iPhone turning off at night. From Reddit:Some other people noted having to put in their passcodes in the morning, an indication that the iPhone restarted or shut off during the night. 9to5Mac highlighted these issues earlier this week, and we've also experienced the problem here at MacRumors, as have multiple users on the MacRumors forums. From MacRumors:You can tell if your iPhone turned off at night by opening up the Settings app, navigating to Battery, and checking the charging status over the past 24 hours. If there's a gap, the iPhone was turned off for a period of time.

The problem affects iPhone 15 models, but it is also impacting other devices, suggesting that it's something in iOS 17. Not all users are experiencing the shutdown issues, nor does it appear to be happening every night.

It is not yet clear what is going on, and Apple has not commented.

Just this morning I had to re-enter my passcode.

FWIW I also had to reset all of my location settings with respect to privacy to off.

They were all on and the option to have the status icon was set to off.

Very strange.
 
Yeah, I think yesterday morning I had to re-enter my password on a 14 Pro. I remember looking at Macrumors to see if maybe an OS upgrade had gone out and my phone had installed it.
 
had this happen the other night on an iphone 11 Pro on the newest OS, 5-6 hour gap on my battery meter
 
Happened to me.. I wondered why I had to re-enter my password yesterday morning after it said my phone had restarted... 15 Pro.
 
Damn. Good thing I got this trusty AM/FM alarm clock from Sony, which I set to blast my eardrums off whenever I have to teach classes early in the morning, shortly before the speaker on my 3G Retina iPad decided to crap itself.

I guess the Apple Watch might still work and do the trick, but it's not nearly as loud as the alarm clock, the iPad (which seriously gave the clock's massive speaker a run for its money) or the iPhone…

Oh, Apple, Apple… And what if someone needs to contact us in the morning (or at any other time, for that matter)? The ramifications are too serious; a phone shouldn't be shutting itself down willy-nilly, especially when not in use. 🤦‍♂️

So this is what's going on - my work phone has done this twice and thought it was some enterprise thing.

The gap's duration itself isn't the problem; the fact that alarms won't go off and calls won't come in until you input your password is. I mean, it's a good thing that it works like that by design, but it was never a problem because iOS doesn't just update itself without warning, and iPhones don't usually bork themselves like that.

I mean, you're not wrong. All their OSes may be full of bells and whistles now, but the overall quality thereof has seriously declined. Heck, they're even making dumb UX decisions left and right, and the new internal naming conventions of system files in macOS are even worse than Microsoft's, they are pushing the limits of human readability.

Long gone are the days of com/org.[developer].[app].plist syntax and other niceties for prosumers and professionals, it's all a complete and unmitigated mess now. I'm getting serious Vista (*cough* UAC *cough* TCC *cough*) and even Windows Me (or, for the really old-school kids here on MR, and not early-SJ-cycle switchers like me, Word for Mac 6.x) vibes from their latest releases… 🤦‍♂️

This isn’t new to me. Since testing the Public Betas all the way back on my iPhone 11, I would wake up and have to re-enter my iPhone password. Seems like springboard crashes? I’ve only had the restart issue, not the complete shutdown.

This just recently happened on my 15 Pro after updating to 17.1 PB2.
