Huawei mate40pro wired charging and wireless charging cannot be used at the same time. When using wireless charging and wired charging, the device will automatically choose wireless charging or wired charging, which is determined by the system default. Wireless charging principle:
1, electromagnetic induction type: the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
2, magnetic field resonance: composed of energy sending device, and energy receiving device, when the two devices adjust to the same frequency, or resonance at a specific frequency, they can exchange each other's energy.
3, radio wave type: similar to the early use of the ore radio, mainly composed of microwave transmitter and microwave receiver, can capture the radio wave energy bounced from the wall, adjust with the load while maintaining a stable DC voltage
The Huawei met40pro can charge both wired and wireless

The Mate40 Pro retains the previous generation's highly recognizable \"Oreo\" design, but the camera and flash are unified in the outer ring, which is called the \"star ring design\" by Huawei. Of the four circles in the Pro star ring, three are cameras, and the upper right is a laser focus sensor.
