How to troubleshoot iPhone X that keeps crashing or shutting down

Before you begin troubleshooting, open the App Store app and then check for any pending app updates. Installing app updates is usually needed after updating iOS to ensure all apps are up-to-date and able to work with the new iOS platform. App developers usually push updates for their apps soon before or after a new iOS version is released. These updates may also contain fix patches to clear any bugs from certain apps. You can update apps individually or simultaneously.

First solution: Force restart your iPhone X.

A force restart is an alternative way of restarting or performing a soft reset on an iPhone. It forcibly clears background apps and dumps cache from the internal memory including those that were corrupted and caused certain apps or iOS to go rogue. Here’s how it’s done:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. Finally, press and hold the Power/Side button until the Apple logo appears.

Like a soft reset, force restarting the iPhone won’t erase any saved data on the internal memory, hence all your files remain intact.

Second solution: Manage and free up internal memory.

Although it may sound bizarre for a high-capacity smartphone to run of storage space at an early stage, it’s not impossible. Rogue apps, malware and buggy updates can trigger memory errors to occur and eventually results to similar symptoms. To clear this out, check and manage the internal memory of your iPhone X with these steps:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Select iPhone storage.

Check how much storage space is used of the total available memory. If necessary, you can free up additional storage space by deleting unused items like unnecessary apps, music, photos, videos, and old messages.

Third solution: Reset all settings on your iPhone X.

The new update can override your current settings if it’s programmed to work that way. This therefore makes it possible to yield invalid settings, which may trigger system errors to occur. When this happens, some apps may become erratic or the device itself can go rogue. In that case, resetting all settings on your iPhone can help. Here’s how:

  1. Tap Settings.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Reset all settings. This will clear your current iPhone settings without affecting any data.
  5. If prompted, enter the correct passcode for your iPhone to continue.
  6. Then tap the option to confirm all settings reset.

Wait for your iPhone to reset and restore system settings to their default or original configuration. When the reset is finished, your device will reboot automatically. By then you can set up and configure individual options, or enable necessary features according to your preferences.

Fourth solution: Restore your iPhone X in iTunes.

A more advanced solution may be necessary, if the problem persists up to this point. The new update might have caused complex system errors to occur and that likely requires more advanced solution. In this case, you can proceed with an iPhone restore through iTunes. Refer to these steps whenever you’re all set to continue:

  1. Get your computer ready and then connect your iPhone X using the supplied USB cable or Lightning cable.
  2. Open iTunes on your computer then allow it to recognize your iPhone X.
  3. If prompted with the option to Trust This Computer, tap OK then follow the onscreen instructions to continue.
  4. Select your iPhone X when it shows up in iTunes.
  5. Navigate to the Summary section then click the Restore [device name] button.
  6. If prompted with the confirmation message, click the Restore button to confirm. Doing so will then trigger iTunes to erase your device and install the latest iOS software.

Follow the rest of the onscreen instructions to complete the system reset. After the reset, you can set up your iPhone as new.

If the previous method doesn’t help, then you can proceed and try performing a recovery mode restore. This is where you’ll need to enter recovery mode and then perform an iOS restore through iTunes. Again, you will use iTunes on a computer to get this done. Here’s how:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. Finally, press and hold the Power/Side button until the Recovery Mode screen appears. Do not release the button when the Apple logo appears because you need to access recovery mode.
  4. Once you see the recovery mode screen or Connect to iTunes screen, wait for the Restore or Update prompt to show up. Then select the option to Restore.

Wait until the system restore is finished and then set up your iPhone as new.

Fifth solution: DFU mode restore.

This would the last-ditch solution you can try on. It’s the deepest type of system restore you can do on an iPhone. It puts your iPhone in a state wherein it’s still able to communicate with iTunes on a computer without activating the bootloader. All data, settings, and apps are cleared in the process along with complex bugs and malware. To get started, connect your iPhone to the computer via Lightning cable, and then continue with these steps:

  1. Press and quickly release the Volume Up button, then quickly press and release the Volume Down button. Finally, press and hold the Side/Power button until the screen goes black.
  2. As soon as the screen turns black, press and hold the Volume Down button while keep holding down the Side/Power button.
  3. After 5 seconds, release the Side/Power button but keep holding down the Volume Down button until your iPhone X shows up in iTunes.
  4. Release the Volume Down button as soon as your iPhone shows in iTunes.
  5. Follow the onscreen instructions to restore your iPhone X in DFU mode through  iTunes commands.

Once the restore process is finished, you can set up your device to use it again. A more detailed content on how a DFU mode restore works on an iPhone can be found on our Troubleshooting page.

Seek more help

If all else failed to resolve the issue and your iPhone X is still crashing or shutting down randomly, take it to an Apple-authorized service center in your area and have it examined by an iPhone technician for any indications of hardware damage. There may be some sort of physical and liquid damage, which therefore requires service. For other options and official recommendations, contact your carrier or Apple Support. They should assess the problem thoroughly given that it occurred after an iOS update. A fix patch may be necessary to deal it.
