Although wireless charging can be unplugged, the distance between the phone and the charger is very small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger.
Despite significant advances in wireless charging technology, there are still some challenges.
