There are certain things that you can anticipate third-party app compatibility issues.

1. Battery Drain

Data from Vanker:

iOS 16 Betteray Testing

Downgrade from iOS 16 to iOS 15 stable version is the best solution for now, or you can restrict the apps from running in the background and update the applications manually. Turn off iOS 16 keyboard haptics, Airdrop, ect.

2. Overheating

It's okay if your iPhone is producing so little heat that you can't feel it. However, if your device is hotter than usual after the update. You might find yourself a little nervous about encountering these iOS 16 bugs.

Don't worry. After an update, some apps will display an iOS 16 error and automatically start updating in the background. Since your device has to multitask, it will emit more heat than usual.

Stop the background running apps, disable the "Automatic update," and reboot your device.

Sep, 23rd, 2022 Update: iOS 16.0.2 Public is available to fix this issue now, it also fix the shaking of camera issue while you are taking photos on third-party Apps.

Apple finally fix this annoying issue on the newest iOS 16.2 Beta, only seven days after the last update.
