Heating is a normal phenomenon of inductive wireless charging, because in the process of wireless transmission, energy will be lost, and heat will be generated. It is recommended not to play with the phone while charging and pay attention to heat dissipation.
Avoid charging at a higher room temperature, which will reduce the charging efficiency. When the detection temperature of the mobile phone reaches 40 oC/104oF, the charging efficiency will be reduced or even the wireless charging function will be turned off. When the temperature drops, the wireless charging will automatically start.
