I am just changing my iPhone 7 and playing ark when it starts getting almost to hot to touch
If it isn’t “too hot to touch"and if you’re not getting any error messages, I will say that this appears to be normal. You are using the device intensively (playing a game) and charging it at the same time. It’s normal for the phone to get hot. Rest assured, the iPhone contain several thermistors designed to measure and monitor the heat of the logic board and if anything goes out of spec, you will see an error message.
