Why Does Your Phone Get Hot When You Charge It?

Your phone gets hot when you charge it because it’s working hard to take in power. Imagine your phone is like a toy that needs energy, the battery inside is like a small tank for storing that energy. When you plug it in, it starts filling up its tank, and that process makes it feel warm, just like how your face gets warm when you’re running.
