Smartphones get warm when they charge because the electricity is working really hard to fill up the battery. Imagine your phone is like a water bottle, and charging is like pouring water into it quickly, the faster you pour, the warmer the bottle gets. The same thing happens with your phone’s battery: when it's charging fast, it creates heat.
Examples
- Your phone feels like a hot potato after charging it for 10 minutes.
- Your phone gets warm when you use fast-charging on a cold morning.
- The back of your phone becomes slightly hot when it’s charging overnight.
