my phone still appear temperature warning screen

Hi nixamhamid,

Thank you for posting to Apple Support Communities.

If you’re experiencing issues with your iPhone getting too hot, you'll need to move to a cooler environment. It may take some time for your iPhone to cool down. Make sure your iPhone is out of the sun.

We see you've referenced the related article If your iPhone, iPad, or iPod touch gets too hot or too cold - Apple Support. Please review section "If you see a temperature warning screen".

Cheers.
