My iPhone 11 is heating up fast

If your iPhone 11 heats up quickly and doesn't show maximum battery capacity, it could indicate a software or hardware problem.

Make sure you have the latest version of iOS installed. Go to Settings > General > Software Update. If you have the latest version turn the phone off and on again to refresh the system.

It is possible that the battery already needs to be replaced and this could be causing the problems.

If nothing helps you should investigate this issue in the service.
