Why some mobile phones don't support wireless charging

2019-10-24 13:57:01

The principle of wireless charger is to use electromagnetic induction. The function of the coil on the electronic PCBA patch of wireless charging is to generate a magnetic field. The receiving end coil of the mobile phone is close to the wireless charger (when the wireless charger is connected to the power, the magnetic field will be generated through the PCBA coil, and when the receiving end coil of the mobile phone is close to the magnetic field, the current will be generated), and the mobile phone will show that it is charging.

Generally speaking, it's easy to understand that there is a built-in transmitter in the wireless charger, and the receiver must be built in the mobile phone to support wireless charging. The official point is that as long as the mobile phone meets Qi standard, it can support wireless charging.

The mobile phones that do not meet Qi standard are because the mobile phone manufacturer does not have a built-in receiver when they leave the factory. Through our unremitting efforts, mobile phones that do not meet Qi standards can also achieve the purpose of wireless charging as long as a receiving chip is external. In the future, all mobile phones will meet Qi standards, and wireless chargers will be widely used in all kinds of places in our life. For example: hotels, cafes, restaurants, bars, desks, homes, cars, public places, etc.
