Tip 2. Uninstall the App That Is Causing iPhone to Restart

In most cases, iPhone or iPad restarts randomly due to faulty apps. If your iPhone keeps restarting after you install a specific app, try to uninstall the problematic app and then check whether the bug can be removed itself.

In addition, Apple provides a feature called "Analytics" that works effectively in diagnosing issues on iPhone. If you are not sure which app causes the restarting, you can go to Settings > Privacy > Analytics Data to check for any problematic apps. If you find any app in the list, just uninstall it to solve the restarting issue.
