Some iPhone Models Mysteriously Shutting Off at Night

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:

Hijacking top comment. Check your battery settings and see if there is a gap during the night. Yesterday a lot of iPhones turned off for a few hours during the night. In my case the phone turned back on 1 minute before the alarm

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:

So my iPhone 15 Pro Max with iOS 17.0.3 spontaneously rebooted last night (10. October around 01:00 AM CET). The same happened to 3 of my friends with the same iPhone and same iOS, and to someone else with an iPhone 13 Mini, also on the same iOS.

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.

Not to worry everyone, for Apple Support has provided an update! This is not an issue, because if it was, Apple Support would know about it before it ever affected a single customer because Apple Support talks to millions of customers a minute. So, to address this known issue, you’ll need to restart your phone. If the issue persists, you’ll need to erase and reinstall using iTunes. If the issue still persists, you’ll need to do an RTA to Engineering, who will get back to you in 48 hr to tell you they are aware of the issue, keep your device up to date, and no further troubleshooting will be provided.

Oh, and thank you for being an Apple customer and we hope you enjoy the ALL NEW iPhone 15, the most powerful, most advanced iPhone Apple has ever released!

It's a mystery why it turns off.

It's a bigger mystery why it turns back on.
