My iPhone XR suddenly stopped working and got very hot and now won’t restart or charge

Hello SimonSY88,

We'd advise starting with the 'If your screen is black or frozen' steps in this article: If your iPhone won't turn on or is frozen - Apple Support. Follow this guidance:

"On your iPhone 8 or later, including iPhone SE (2nd and 3rd generation)

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button until you see the Apple logo.

4. If your phone doesn't turn on, follow these steps to check your hardware and charge your phone. You might need to charge for up to an hour."

If the issue persists, further assistance may be needed. We want to make sure you reach the right team for help with your device, so we recommend that you contact Apple Support directly. Depending on your region, you may be able to reach them here: Get Support - Apple.

Thank you for participating in the Apple Support Communities and have a wonderful day.
