Place Your iPhone in a Cool Place

If your iPhone is already hot, try to keep it in a cooler room that will help it cool down. 

A room with great ventilation is a good option, but you can also put your iPhone near a fan to help it cool down.

Of course, it goes without saying, but don’t put your iPhone inside the fridge. It might seem like a good idea, but the sudden change to a much lower temperature can damage your iPhone by rapidly contracting internal parts or creating condensation inside.
