Why Do Smartphones Get So Hot When You Charge Them?

Smartphones get hot when you charge them because the energy from the charger moves into the battery, and this movement can create a lot of heat. It's like running around in the sun, your body gets warm. The phone’s battery is working hard to take in all that power, so it gets hot. Sometimes, the phone also runs other apps while charging, which adds more heat.
