The principle of mobile phone wireless charging is to transmit electrical energy to the mobile phone battery through electromagnetic induction, so in the process of charging, the mobile phone will heat up. Although mobile phone wireless charging can be played while charging, it is recommended to reduce the use of mobile phones when charging, so as to avoid excessive heat of mobile phones caused by overuse, affecting the charging effect and life of mobile phones. At the same time, you should also pay attention to safety issues, avoid using non-original chargers or charging cables, and avoid charging in wet environments.
