Don’t Use Your iPhone While It’s Charging

As mentioned before, your iPhone doesn’t like charging in very high temperatures, but charging it in low temperatures isn’t ideal either. Don’t worry; that doesn’t mean your iPhone can’t take the heat. Ideally, you want to charge your iPhone in ambient temperatures of 62° to 72° F (16° to 22° C). If you charge your iPhone in very high temperatures, say above 95° F (35° C), you might permanently damage your iPhone’s battery capacity. Not only will it not charge above 80%, but you might notice that your battery doesn’t last as long afterward.
