Why Do Smartphones Stay Cool While Charging?

Smartphones don’t get too hot when they're charging because of a special kind of heat shield inside them. Think of it like wearing a coat on a chilly day, the phone uses materials that help keep the heat from spreading too much. This keeps your phone cool, even though some parts are working hard to charge.
