After ios17 updates my iphone 13pro max is heating during call or video call …please tell me what to do?

Hi there aslam61,

It's normal for your iPhone to get warm in certain situations. If you're not seeing a temperature alert, there shouldn't be any cause for concern. Learn more about that here: If your iPhone or iPad gets too hot or too cold - Apple Support

If this behavior persists, you'll want to reach out to Apple Support directly for further assistance. They're best-equipped to take a closer look at the issue and provide some additional guidance. This link will help you get started: Apple Support

Take care.

if your phone gets temperature alert, that is too late.

ios17.0.3 did not do a thing. I regret to switch from my iPhone 13 Pro which did not have the heating issue at all!
