Sometimes weird issues just pop up.
A number of users have reported that their iPhones have begun rebooting at strange intervals as well as powering down overnight, sometimes causing alarms to be missed.
It’s not presently known as to what may be causing the issue, which seems to be affecting a wide array of iPhone models, some of them running different versions of iOS. While a concentration of affected units seem to be running iOS 17.0.3, there doesn’t seem to be a consensus as to what the exact cause of the issue is.
The core similarity seems to be that the shutdown occurs overnight when the units are charging. The iPhone will ask the user to enter a passcode, as if completing an update. After further inspection, affected users have also noticed that there are gaps in their battery health charts, as the iPhone had powered off.
Other users have reported about Standby widgets resetting after the iPhone “randomly reboots in the middle of the night.”
Apple has yet to publicly acknowledge the issue with iOS 17.0.3, which arrived on October 4. Apple recently released the third beta for its forthcoming iOS 17.1 update, although it’s unknown as to whether this will resolve the issue.
