Why iphone getting heat?

Heating issues often happen when you’re in a hot environment or when background apps are running. Try closing unnecessary apps, turning off Bluetooth/WiFi when not needed, and removing the phone case during charging.

Sometimes overheating may be related to a battery or hardware issue. If your iPhone continues to get very hot even during light use, it’s best to have it checked at an Apple Authorized Service Center. More details here: Apple Support - Keeping iPhone within acceptable temperatures.

iPhones can get heated for many reasons such as heavy gaming, video streaming, or using the camera for a long time. It’s normal to some extent, but if it gets unusually hot, check for software updates and avoid charging while using the phone.
