Smartphones feel warm because they work hard when we use them. When you play games, watch videos, or talk on the phone, it's like asking a person to run around and do lots of things at once, they get tired and start sweating. Smartphones are like that person; they get hot from all the extra work.
Examples
- When you play a game on your phone for a long time, it gets warm because the brain of the phone is working very hard.
- Your phone feels hot when you're watching videos without stopping because it's like it’s running a race inside.
- If you talk on your phone for a long time, it might get warm because it's using all its energy to keep the conversation going.
