Smartphones get warm when you charge them because they are working hard. When you plug in your phone, it starts moving energy from the charger to its battery like a tiny robot carrying bricks across a room. The more bricks (or energy) that need to be moved, the harder the robot has to work, and the warmer it gets. This is why your phone might feel like it's almost cooking while it charges!
Examples
- Your phone feels warm when you charge it on your bed while watching a movie.
- You notice the back of your smartphone getting hot even after it reaches 100% charge.
- Your phone becomes almost too hot to hold when charging with a fast charger.
