Hello desibob1234,

Thanks for reaching out to Apple Support Communities. We see you have some questions about your device getting warm, and we'd like to help. The following link can help explain some tips on what to do when your device gets warm: If your iPhone, iPad, or iPod touch gets too hot or too cold - Apple Support

Your device might get warm

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.

Let us know if this helps.

Regards.
