iphone wireless charging is slow, and here's why:
Because we need to take care of cost, but also pay attention to safety. Therefore, after testing and evaluation, it was finally determined that 7:5W is a safe and cheap solution for the new iPhone to achieve wireless charging, which is certainly much slower than the 15W wireless charging that can be supported now.
The safety factor is Apple's control of heat, the iPhone uses an inductive charging mechanism, which means that the distance between the two coils needs to be very close, and the body will be very hot after charging, so from this aspect, it will also choose a slower charging 7:5W.
