Are you facing a battery drain issue on your iPhone after upgrading to iOS 16? If so, there are a few troubleshooting tips I have mentioned in this guide you can implement to fix the problem. For some users, it may be a bug in the iOS 16 beta version that causes the battery drain issue on the iPhone.

Various other aspects frequently contribute to the iPhone’s battery loss. For example, by stuffing your home screen with widgets, you may not need to drain the battery all the time. Also, keeping a lot of apps running in the background that you do not use actively will consume the iPhone’s juice.

Even using the iPhone in light mode instead of dark mode will require more battery power. Having the location services enabled round the clock for multiple apps also causes faster battery loss.
