Hey you, iPhone user! If you recently updated your device to iOS 16.3.1, you may face severe issues like face detection not working, auto switch off, and the most annoying one, iOS 16.3.1 battery drain. As an existing iOS user, battery draining is an evergreen concern on iPhones, so read the blog at the end to understand how a new iOS update can ruin your device’s battery life.

These types of updates lead to serious battery drain problems, and the new iOS 16.3.1 update is no exception. This update has severe optimization problems and compatibility issues with old iPhones, so iPhones below the year 2021 are struggling to give good battery backup.

Minor bugs could also be part of the iOS 16.3.1 battery life problem. Minor bugs contain some background processes unknown to our iPhones, e.g., a few days ago, some people faced a cellular data bug, in which the device shows that cellular data is off even if it is on. This bug came into existence when some users faced a data shortage in their data plans. We all know that using cellular data consumes more battery than using Wi-Fi. It is just an example; there are a lot of bugs out there in the iOS system that are responsible for battery drain problems.
