One of the most annoying encounters of users is when their iPhone keeps restarting unnecessarily. But you don’t have to be worried or rush to an Apple store for help because this article will show you the methods you can use to solve the issue easily. The built-in setting is usually the safest place to start before you try extra tools.
When your iPhone is still Working
In case your iPhone is still on and working you can use the methods below. Starting with the built-in option first usually makes it easier to tell whether you really need an extra app.
Uninstall bad Apps
One of the reasons your iPhone may be starting randomly is due to bad apps. To know the bad apps, you can check the app usage and determine the apps consuming a lot of power. It is a useful fallback when the default iPhone editor does not give you enough control over the final clip.
Steps:
- Select the Settings app > Battery > Show Activity > Show Detailed Usage so the next part of the process is easier to complete without backtracking.
- click “Battery Usage” to view the percentage used
- To get a detailed usage of power on that day click “last 24 Hours” or any option you want to determine the unusual power usage. If a step looks different on your device, the app version is usually the first thing to compare before assuming the feature is missing.
You can delete or update the apps. To delete them follow the steps below:
- On the Home screen, click the specific app then long-press it until it starts wiggling.
- click the “X” on the app you pressed.
- Confirm to delete from the prompt that pops up.
- click the Home screen to end the process.
If you need to use the app again you can check for the latest version and reinstall it. Once you are done deleting you can reboot your iPhone to clear junk files. That gives you another route if the built-in iPhone tools feel too limited for the result you want.
