Why Do Smartphones Feel So Warm?

Smartphones get warm because they work hard and have lots of little parts inside. Imagine your phone is like a tiny robot that has to do many jobs at once, talking, taking pictures, playing games, and sending messages. When it works hard, it produces heat, just like when you run fast and feel warm.
