How to Fix iPhone XS Max That Keeps Crashing or Shutting Down

If your iPhone XS Max is randomly crashing or shutting down, it can be a frustrating experience. This issue can be caused by software bugs, app conflicts, or, in rare cases, hardware damage. Before you consider taking it to a service center, try these troubleshooting steps to fix the problem yourself.

Clear Background Apps and Reboot Your Phone

Sometimes, running multiple apps in the background can lead to crashes. Here’s how to clear background apps and reboot your iPhone XS Max:

From the Home screen, swipe up and pause to bring up the app switcher.
Swipe left or right to find the apps running in the background.
Swipe up on each app preview to close them.
Reboot your phone:
- To soft reset, press and hold the Side/Power button and one Volume button until you see the Slide to Power Off slider. Slide it to turn off the phone, then press and hold the Side button to turn it back on.
- To force restart, press and release the Volume Up button, then the Volume Down button. Finally, press and hold the Side button until the Apple logo appears.

Test the phone after it reboots to see if the issue is resolved.

Install Pending App Updates

Outdated apps can cause compatibility issues with iOS, potentially leading to random crashes. Here’s how to update your apps:

Open the App Store.
Scroll down and tap the Updates section.
Tap Update All to install all pending updates or tap Update next to individual apps.

Once the updates are installed, reboot your iPhone and check if the issue persists.

Update iOS to the Latest Version

Updating iOS can resolve bugs that might be causing your phone to crash. Follow these steps to check for an update:

Open Settings > General > Software Update.
If an update is available, tap Download and Install.
After the update finishes, restart your phone to ensure all changes take effect.

Reset All Settings

If the crashes started after changing settings, restoring defaults might help. This won’t erase your data but will reset settings like Wi-Fi and display preferences.

Open Settings > General > Transfer or Reset iPhone > Reset.
Tap Reset All Settings.
Enter your passcode and confirm the reset.

After the reset, reconnect to Wi-Fi and test the phone.

Restore Your iPhone Using iTunes

If none of the previous solutions worked, consider restoring iOS via iTunes. This can fix deep system issues but will erase all data, so back up your phone before proceeding.

Open iTunes on your computer and connect your iPhone XS Max using the USB cable.
Select your device in iTunes.
Click Restore iPhone and follow the on-screen instructions.

If iTunes doesn’t fix the issue, you might need to perform a Recovery Mode or DFU Mode restore for a more thorough reset.

Other Options to Consider

Delete Suspected Apps: If the crashing started after installing a new app, try uninstalling it to see if the problem goes away.
Hardware Damage: If none of the software fixes help, physical damage (like liquid exposure or dropping) could be the culprit. Visit an Apple Store or an authorized service center to have your iPhone inspected.
