Heating issue

Hi raji1981,

For help with your device becoming warm when charging, check out the information below found in the article here: If your iPhone, iPad, or iPod touch gets too hot or too cold

"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."

However, be sure to review the details in the section "If your device gets too warm" from the same article. If you continue to have concerns, reach out to Apple Support directly to further assist.
