Numerous iPhone users are facing a confusing problem where their phones unexpectedly shut down at night.
This issue isn't limited to the latest iPhone 15 models; it affects a wider range of devices.
The problem came to light when a Reddit user woke up to their iPhone's alarm, only to be asked for their SIM card's PIN to unlock the device.
Face ID remained inactive until the code was entered. Checking their battery statistics, they noticed a blank period between 3 and 7 AM, suggesting the phone had powered down and rebooted.
This issue is not linked to a beta version; most affected users were using iOS 17.0.3.
It extends beyond iPhone 15 models to older devices like the iPhone 12 Pro and iPhone 13 Mini, affecting users worldwide.
One theory suggests Apple's servers triggered a mass shutdown request, but this doesn't explain the spontaneous reboot.
A more plausible explanation is a kernel panic or overheating, causing a reboot and subsequent boot loop.
The absence of battery statistics during the "off" period raises questions. It remains to be seen if Apple will address this issue as more users report it.
