Don’t Leave Your iPhone Inside Your Car
Even if it’s for a few moments, you shouldn’t leave your iPhone inside your car, especially if your car is under direct sunlight.
The temperature, the sunlight, and the lack of ventilation could cause your iPhone to overheat, and it might even damage it in the long run.
That goes for really hot rooms at home, too. If you have a room that’s too hot or where you know your iPhone will be in the sunlight, it’s best to avoid it.
