The wireless charging and limited charging process of Apple mobile phones need to be matched and identified first before entering the charging link;

Wireless charging is a change in the receiving side coil on the back of the mobile phone that is coupled to the electric energy transmission platform through magnetic field transmission, and can only be started after the special communication protocol is successfully matched. In this process, external charging detection will be advanced. If wired charging is connected before wireless charging, the function of wireless charging will be directly turned off. The communication protocol that does not match wireless charging can only allow wired charging;

If it is forced to realize wireless charging and wired charging at the same time, it will increase the design of the internal protection circuit of its own phone, and deal with the problem of power matching;

The other is that it will lead to increased electromagnetic radiation, because the design of the wireless charging circuit itself needs to be subject to space, circuit loops, costs, in this case, it is better to reduce radiation, but it is close to the limit, but if you want to access the wired charging circuit, it will destroy the original circuit layout, which will directly increase the radiation interference between circuits. Resulting in overall radiation overshoot
