Wireless charging is essentially the same as wired charging, except that wireless electromagnetic waves are used to transmit electrical energy during the charging process. Therefore, under normal circumstances, wireless charging will not cause harmful effects on the phone, nor will it reduce its charging speed or affect the battery life.
However, if you use the wrong charger or choose an incompatible charger, it may have a negative impact on the phone. For example, the charger output power is insufficient, the voltage is too high may lead to low charging efficiency, heat, battery damage and other problems. Therefore, when choosing a wireless charger, you should choose products with a good brand reputation, operate in strict accordance with the instructions, and avoid using poor quality and poor compatibility chargers to protect the safety of the mobile phone and its battery, and ensure charging efficiency and life.
