My 2018 iPad Pro did the same thing last night. Weird. Guess I’ll keep using it until they make a compelling enough reason to replace it.

Some iPhone Models Mysteriously Shutting Off at Night

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)
But it asked for my PIN code like usual when powered on so it was definitely rebooted
Didn’t need to, back then we had Nokia 5110 and the alarm still went off if you turned the phone off at night!
No, mine does that as well sometimes after a while. But the phone never restarted (I don't charge the phone overnight)
I do think this would require more testing. Maybe some power draw measuring during the night. This would really quickly tell if the phone is off or not.

My iPhone 12 rebooted mysteriously last night around 20 mins after I put it on the MagSafe charger
I do recall having to enter my passcode the other day. And I remember thinking at the time “Oh. Why do I need to enter my passcode?” But then I just quickly entered my passcode and went about day without giving it another thought (until now).
It happened more than 24 hours ago, so my battery level screen will tell me nothing about that specific instance (and maybe my specific instance had absolutely nothing to do with my phone shutting off). I’ll keep an eye out, but I haven’t had any possible issues since (if I ever had any issues to begin with).

I have notice it this night first time. Before it was normal.
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.

This happened to me with my new iPhone 15. I searched the analytics for clues but couldn’t find any. Luckily my morning alarm rang right before it happened.
Would anyone familiar with logs know if PerfPowerServicesSignpostReader could hold the clue?
