Why does the POCO F7 Ultra overheat when charging and playing games?

When you use it normally, the screen and processor work continuously, and the whole device will heat up to a certain extent. At the same time, the POCO F7 Ultra uses the latest 120W charging technology, and the charging rate is at the leading level in the industry. Fast charging will be accompanied by a certain amount of heating, which is also normal.
Using and charging at the same time will cause the heating to overlap, and it will feel even hotter, especially in high energy consumption scenarios such as running games. If you feel that the heat is unbearable, it is recommended that you use the phone less frequently while charging to improve the temperature rise experience.
