It appears that several iPhones out there are mysteriously turning off for a short period at night, which is interrupting alarms and other features.
In a thread on Reddit, one user says that two separate alarms he had set on his iPhone failed to go off. Several other users also reported similar issues, and it appears the users’ iPhones are 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
Other users say they’re required to enter their passcodes in the morning, which is an indication that the iPhone shut off or rebooted sometime during the night. 9to5Mac reported on these issues earlier this week, and multiple users on the MacRumors forums. report seeing the issue.
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.
To tell if your iPhone turned off at night, go to the Settings app, tap on “Battery,” and check the charging status over the past 24 hours. If you see a gap, that means the iPhone was turned off at some point during the night.
The problem appears to affect iPhone 15 models, as well as other devices, suggesting that there is a bug in iOS 17. However, not all users are seeing the shutdown issues, nor does it appear to be happening every night. (We here at Mactrast haven’t experienced this issue.)
Apple has not commented. If and when it does, we’ll report it in this space.
