iPhone X, iPhone XS and iPhone XS Restarting Fix

If your iPhone X keeps restarting, don’t panic, there’s a likely solution. Take these steps first to fix the restart cycle:

1. Force Restart First

The first thing to do when your iPhone X keeps restarting is to force a ‘hard reboot’. If your iPhone X is stuck on a restart loop, this is the best chance to get it to stop. For this model, quickly press the Volume Up button, and then the Volume down button (release immediately with both). Then hold down the side Power button until the Apple logo comes up.

1. Update to Newer Software, Then Older

Much like the other iPhone models, updating the apps and iOS on your iPhone often fixes a restart problem. That said, if the problem happens to be with a more recent update, hook up to your iTunes store and restore your iPhone to a previous backup.

1. Optimize Your iPhone X’s Performance

Sometimes iPhones can get weighed down by a bunch of little extras. Running background apps, keeping GPS on, and neglecting ‘clutter files’ can add up to a bigger problem. They all drain your battery, and make it difficult for your iPhone to achieve peak performance. Get rid of old apps, turn off apps and GPS when you’re not using them, and get rid of digital clutter. Clear the caches of your apps and browser to get up to speed, and delete unnecessary files
