Apple Intelligence is now available on iPhone, iPad, and Mac!
Just I have purchased I phone , it has been heating (1) while using safari browser, observed heating back near camera and (2) while charging same and front side too.
I have restarted but the issue persisted
iPhone 12
The issue will persist because the device burning energy faster than it could store it, hence why you're experiencing this. For this issue to stop, you must let the phone recharge without overusing it. this goes for all tech devices. there are times even the charger block will overheat.
