Smartphones feel hot because they work hard and get tired. Think of your phone like a person running a race, when it's doing lots of things at once, like playing games or watching videos, it gets really busy inside. The parts that make everything happen (like the battery) are like muscles working overtime. When muscles work too much, they get warm, and so do your phone’s insides. That heat makes your phone feel hot in your hand.
Examples
- Your phone becomes hot in your pocket when you’re watching a video without moving it.
- Your phone gets warm quickly if you use it while charging.
