Why Do Smartphones Feel Warm to the Touch?

Smartphones feel warm because they work hard like a little engine. When you're scrolling, gaming, or watching videos, the phone uses energy and gets hot inside, just like when you ride your bike fast and feel warm after. The heat comes from the battery, which gives power to everything else in the phone.
