Moving energy from a charger into a battery is not perfectly efficient, so some of that energy becomes heat. The phone itself may also be using power at the same time.</p> <p>What matters is the difference between ordinary warmth and a device becoming hot enough that it has to protect itself. Modern phones monitor temperature and can reduce charging speed, limit performance, or pause charging when conditions become unsuitable.</p>
