iPhone Models Are Shutting Down For No Reason at all After iOS 17.0.3 Update, Disabling Some Features

wccftech.com:

If your iPhone turns off at night for no reason, you are not alone. Some users have reported that their iPhone temporarily turns off overnight which can cause some features to stop working as they should. Apple recently released iOS 17.0.3 to the general public, fixing one of the most crucial issues on the iPhone 15 Pro models. While the update did fix one issue, it brought another to the table.

A few days after Apple launched the iPhone 15 and iPhone 15 Pro models, it was discovered that the 'Pro' models were overheating. Initially, the reason for the issue was unknown and analysts predicted that it could either be the new A17 Pro chip or the titanium finish. Additionally, it was also reported that a bug in Instagram was causing the devices to overheat. However, Apple stated that it was not a hardware issue as the company released iOS 17.0.3 to fix the iPhone 15 Pro's overheating issues. Now, users who have updated to iOS 17.0.3 suggest that their iPhone turns off overnight.

Users have shared their experience in a Reddit post, suggesting that their alarms failed to go off. Potentially, the reason for the issue could be the iPhone turning off overnight temporarily. The device does turn on in the morning but requires users to put their passcode in. This could temporarily stop some features from working such as notifications as well as alarms. When the iPhone is restarted, it will not connect to WiFi unless you unlock your device. Currently, Apple has not shared its side of the story, so be sure to stick around for more details.
