Smartphones get hot when charging because they're working hard. Imagine you’re running on a treadmill while someone pushes you, that’s your phone! When it's charging, the battery is like the treadmill: it needs energy to keep moving, and some of that energy turns into heat. If you use your phone at the same time, it gets even hotter, because now it's doing two things at once.
Examples
- Your phone gets hot when you charge it because it's like running on a treadmill while someone pushes you.
- If you're watching videos on your phone while charging, it will feel even warmer than if you just left it alone.
- You might notice the back of your phone getting warm during the night when it charges overnight.
