Update Your Apps

Updating your apps is as much important as updating your iOS version. So, make sure that all the apps on your iPhone are up to date.

The best routine is to update all the apps on your device regularly. So, make sure you follow that practice.

Some recently purchased third-party apps may cause this problem. In order to reduce the possibilities for the rebooting issue, we recommend deleting the apps that you updated or bought recently before experiencing the problem. We also suggest targeting the apps updated or installed before the latest iOS update on your iPhone. I know that this may not be so easy for some of you, so here are some tips.

  1. First, try to remember if you upgraded or installed an app, right before your device started this weird behavior.
  2. If you are unsure (like me), take a look at the date when you installed the latest iOS update.
    1. Go to Settings and tap on General.
    2. Open the Software Update section and take note of the date.
  3. Now, open your App Store and check the apps you updated or installed since that time. (Make sure you include the day of the iOS update as well)

Check Your Charging Port

Sometimes the cause for the rebooting iPhone issue might be your charging port. To get rid of the issue, take a look at the Lightning port on the bottom of your device. Specifically look for any dust, dirt or debris stuck in the hole. If you notice something, make sure you clean the lightning port. Here you can find a detailed explanation how to clean it properly How to Fix Your iPhone 8/8 Plus and iPhone X Charging Issues. This will hopefully fix your problem.

Note: Before you start examining and cleaning the charging port, make sure you remove any protective cases, headphone jacks, or lightning connectors.

Check Analytics

Another crucial thing to do if your iPhone keeps restarting itself is to check the Analytics (Diagnostic and Usage) data. Here is how to do that.

  1. Go to Settings and tap on Privacy.
  2. Scroll down and tap on Analytics, then open Analytics Data. (For iOS 10 or older, tap on Diagnostic & Usage and then open Diagnostic)

  5. Now, check if that fixed your problem.

Reset All Settings
