Part 1. 6 Crucial Methods to Fix an iPhone that Randomly Restarts

You could be on an active call, FaceTime or just browsing through when your device shuts off all by itself. It can be acceptable if it happened once or twice but a series of random restarts is already annoying. It hinders you from using your phone to the fullest because you need to wait till the device boots up and repeat whatever you were doing prior. Follow these 6 troubleshooting methods to fix an iPhone that randomly restarts:

Method 1. Hard Reset iPhone

The simplest form of troubleshooting that you can do to get rid of an iPhone that keeps on restarting randomly is to hard reset it. This is also the first thing that Apple techs will do if you bring it over to the store. This process will cut off any software processes at the time and give your device a fresh start-up. To hard reset your iPhone varies per model, check out this guide: iPhone X, XS, XR, 11, 12, or iPhone 13:

  • Press and quickly release the volume up button
  • Press and quickly release the volume down button
  • Press and hold the side button and release when the Apple logo appears

For iPhone 7:

  • Quickly press and release the Volume Up and the Sleep/Wake buttons until the Apple logo appears.

iPhone 6 and below:

  • Press and hold the Sleep/Wake and Home buttons at the same time and quickly release the buttons when the Apple logo appears.

Check whether your iPhone still randomly restarts after doing a hard reset, if yes, you can proceed to the next methods.

Method 2. Reset All Settings

Maybe you have tweaked a few settings right after an update causing some miscommunication on your device and resulting in random restarts. You can try to reset all your settings to see if it works.

Although this method is not a guarantee to fix the random rebooting, it can help!

Reset All Setting to Fix iPhone Randomly Restarts

  1. From your home screen, go to Settings
  2. Click General
  3. Find and tap Reset
  4. Select Reset All Settings

Your network settings will be back to default so you need to enter the Wi-Fi password again and also your Home screen layout, keyboard dictionary, Apple Pay card, privacy setting, and other customizations you made will be removed. However, your media files and other data are still safe.

Method 3. Remove SIM Card

An iPhone that randomly restarts can also be triggered by its connection to your wireless carrier. You can simply remove the SIM card from your device for a few minutes and try using the iPhone without it just to test if the random restarting is still occurring.

  • Use a paper clip or the included SIM-eject tool to pop open the SIM card tray.

If the restarting still happen even without a SIM card, then proceed with the next troubleshooting method.

Method 4. Manage Device Storage

Do you have tons of apps on your device? Having low storage can also cause your iPhone to randomly reboot. You can use your device to monitor the storage and identify which apps are eating a lot of space and decide which ones to remove.

Follow these steps on how to manage your iPhone storage:

  1. Open Settings
  2. Go to General
  3. Find and tap Storage

In here, you will see a list of all the installed apps and the volume of space each one uses. Tap an app and you will have all the detailed information plus you can offload an app, which clears off temporary data and caches, and you can also delete an app if you think it’s no longer useful.

There will also be a storage full alert to notify you that your iPhone is already clogged and needs some space to optimize its performance.

Method 5. Update iOS

A software update can fix any software-related issues like random restarts. Most of the time, random restarts are caused by software bugs that can be eliminated by a newer version.

To check if there is an available update, go to your phone’s Settings, tap General, and select Software Update. Tap Download and Install if necessary. However, the problem with this method is that your iPhone randomly restarts and if you perform an update, your device might shut off in the middle of an update, and this can’t be good. Better proceed with the next method to fix this issue.
