Smartphones get hot when charging because they're working hard to store energy. When you plug your phone into a charger, it’s like giving it a big drink of power, and just like how you might feel warm after drinking something cold quickly, the phone feels warm too. The battery inside is doing most of the work, so it gets especially hot. If the phone is also running other apps or playing games while charging, it’ll get even warmer.
Examples
- Your phone feels like a hot potato when you charge it for too long.
- When your phone is charging and you're playing a game, it gets even warmer than usual.
- Sometimes your phone becomes so hot that it starts to feel uncomfortable against your skin.
