My iPhone xs-max Screen freezing and restarting after last update 16.1.1

Hi halimo2m,

Thanks for posting in Apple Support Communities.

We understand that your iPhone has become hot and started freezing up since you updated iOS. To address this behavior, go to Settings > Battery > Battery Health and make sure that there aren't any alerts and that your battery isn't 80% or below. Having a depleted battery could cause performance issues.

Make sure that you're keeping iPhone in temperatures between 0º and 35º C (32º to 95º F. It is not uncommon for certain tasks to cause iPhone to become warmer such as charging.

You might notice that your device feels warmer when you:

*Set up your device the first time

*Restore from a backup

*Wirelessly charge your device

*Use graphics-intensive or processor-intensive apps, games, or features, including augmented-reality apps

*Stream high-quality video

These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity. If your device doesn't display a temperature warning, you can keep using your device.

You can find these and additional details in If your iPhone, iPad, or iPod touch gets too hot or too cold and If your iOS or iPadOS device restarts or displays the Apple logo or a spinning gear unexpectedly.

Regards.
