This troubleshooting method is also related to the apps. If updating the apps didn’t solve the problem, watch the apps behavior.

  • You can remove those apps one by one while checking what happens after you delete the app. For example, on my “suspicious apps” list, I will first remove WhatsApp only, then I will observe if the iPhone randomly restarts or not? If yes, then I will continue deleting the other suspicious apps one by one.
