Originally Published 2 years ago — by MacRumors

The upcoming iOS 17.1 update does not fix the nighttime shutdown bug affecting some iPhone models, causing alarms to fail and notifications to be silenced. The issue persists on devices running both iOS 17.0.3 and iOS 17.1, impacting various iPhone models, including the iPhone 15. Users can check if their iPhone turned off at night by checking the charging status in the Battery settings. Apple has not provided a timeline for a fix.
