Smartphones get warm because they are working hard. When you're playing games or watching videos, the phone's brain, called the processor, works really fast to keep everything going. This makes it hot, like when you run and sweat a lot.
Examples
- Your phone gets warm when you're playing a game for a long time.
- It feels hot after watching a movie on a very bright screen.
- The back of your phone is like a tiny heater when you use it in the sun.
