Why shouldn’t you charge your phone under a pillow?
Charging creates heat. A pillow, blanket, or couch cushion traps that heat around the phone and battery instead of allowing it to escape. If the battery or charger is damaged or defective, overheating can become a much bigger problem.
Charge devices on a hard, uncovered surface using the correct charger. If something becomes unusually hot, starts swelling, smells strange, or makes odd noises, unplug it if you can do so safely and stop using it.
