Google Pixel 3 XL reboots by itself after a few hours of use

Random reboots are usually due to a firmware unless your phone has suffered either physical or liquid damage. A high-end device like the Google Pixel 3 XL may also have this kind of problem despite having really good hardware specs. In fact, many have already resorted to online forums asking for help as their phones started to reboot by themselves without apparent reason or cause.

In this post, I will walk you through in troubleshooting your Pixel 3 XL that restarts by itself. We will try to look into every possibility and rule them out one by one. I personally encountered several cases in the past and I know you can fix it on your own. So, if you’re one of the users who are currently having similar symptoms, continue reading as this article may help you one way or another.

Before we move on, if you have other issues or if you’re looking for a solution to a different problem, then drop in on our Pixel 3 XL Help Guides for we have already solved some of the most common cases with this phone. There could already be articles on our website that could help you fix your problem.

Now, going back to our troubleshooting, here are the things you need to do if your Pixel 3 XL keeps rebooting by itself…

Run your phone in Safe Mode. by running your Pixel 3 XL in safe mode, you’re temporarily disabling all third-party applications. In this step, we are trying to determine if the random reboots are caused by third-party applications. So, you need to continue using your phone in safe mode and actually wait for it to reboot because if it doesn’t, then it means there really is an app or two that’s causing it to restart by itself. You have to find out which among your apps is the culprit and uninstall it. Here’s how to reboot your Pixel 3 XL in safe mode:

  1. With the device powered on, press and hold the Power button (located on the right-edge) until the Power off prompt appears then release.
  2. Touch and hold Power off until the “Reboot to safe mode” prompt appears then release.
  3. Tap OK to confirm.
  4. The restart process may take up to 45 seconds to complete.
  5. Upon restart, ‘Safe mode’ appears in the lower-left of the unlock/home screen.

On the other hand, if your phone turned off by itself and you’re having a difficult time booting it up, then try to power it up into safe mode. Here’s how it’s done…

  1. Press and hold the Power button until the Google logo appears on screen then release.
  2. With the Google logo still on screen, press and hold the Volume down button.
  3. Continue to hold the Volume down button until ‘Safe mode’ appears in the lower-left of the unlock screen then release.
  4. This may take up to 30 seconds.

Finding out the culprit may take time so it’s better to continue using the phone in safe mode for a day or two. If the phone doesn’t reboot on its own while in safe mode, then the problem is pretty easy to fix. However, if the phone still reboots even in safe mode, then move on to the next procedure.

Reset your phone. Doing this will bring the phone back to its default configuration. However, make sure to backup your important files and data as they will be deleted during the process. If the phone reboots by itself even in safe mode, then it’s more likely a firmware issue and since we don’t know for sure what the problem is, a master reset should be done.

  1. Ensure the device is powered off.
  2. Press and hold the Power+Volume Down buttons until fastboot mode (image of triangle with exclamation point) appears, then release.
  3. Select Recovery mode.
  4. From the Android Recovery screen, select Wipe data/factory reset.
  5. Select Yes.
  6. Select Reboot system now.

Allow several minutes for the factory data reset and reboot processes to complete.

I hope that we’ve been able to help you fix the problem with your device. We would appreciate it if you helped us spread the word so please share this post if you found it helpful. Thank you so much for reading!
