Iphone 7 plus heating over WiFi upon video calls (FaceTime, Duo, WhatsApp)

Hello,

This is CBanala from India.

I have been continuously facing overheating issues with iPhone 7 plus since i upgraded to iOS 15.0.2, in last month.

It is even happening while using cellular mobile data as well as over WiFi upon video calls (FaceTime, Duo, WhatsApp).

I am afraid if there could be any damage to battery or processor cooling system.

Can somebody have similar issues found& got it fixed, could be of great to know exact fix.

Thanks & looking forward to your kind help.

Best regards,

CBanala
