NFC wireless charging is not to charge the mobile phone, which has little impact on mobile phone charging. In my opinion, the more likely impact of NFC support for wireless fast charging on mobile phones is that mobile phones integrate NFC modules, and there are more supporting devices that can achieve charging life through mobile phones in the future, greatly enriching mobile phone application scenarios.
Some mobile phones now support wireless reverse chargingIs built on the basis of wireless charging, mobile phones do not support wireless charging, it can not carry out reverse wireless charging. With NFC wireless charging, even if the mobile phone does not support wireless charging, it can also use NFC to charge other devices.
However, the use of NFC for wireless charging, the power and today's maximum 40W or even higher technology is not comparable. According to the NFC Forum, WLC (Wireless charging via NFC Solution) can use an antenna in NFC-enabled devices to manage communication and charging, so currently only 1 can be achieved through this solutionW charging speed. < / p > < p > the WLC is called WirelessChargingSpecification last year has been included in the NFC wireless charging standard candidate, was formally adopted this year to become the official standard, its characteristic is the output power of 1 w, compared with the 15 w Qi state is still small, However, it is quite enough for some devices that use small batteries, such as smart wear, real wireless headphones, and stylus.
Does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large.

Enter "Battery vsOn the navigation bar, click the Battery TAB. In the battery usage Settings, find the "Wireless reverse charging" feature and make sure the switch next to it is on. Follow the above steps to successfully enable the wireless charging function of the Mi 13.
3, the wireless charging function of Mi 13 is very simple to use, just connect the wireless charger to the power supply, and then place the phone on the charger to start charging. The Mi 13 has a 36-inch E6 straight screen and is available in remote Mountain blue, Wilderness Green, black, and white, as well as limited custom Jungle green, Fiery Red, and HurricaneWind yellow, cement gray, sapphire blue five color options.
4, the use of wireless charging of the mobile phone is as follows: the wireless charger is connected to the power, without any setting on the mobile phone. Place the phone on the wireless charger to start charging. It should be noted that the output current of the wireless charger is small, the charging speed is slow, and it takes a long time to charge.
There are four mainstream wireless charging standards: Qi standard, Power Matters Alliance (PMA) standard, Alliance for Wireless Power (A4WP) standard, iNPOFi technology. Qi standard Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility.
There are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric fieldCoupled charging, the mainstream standards on the market mainly include Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
There are three mainstream wireless charging standards: Power Matters Alliance (PMA) standard: The Power Matters Alliance standard was initiated by Duracell Powermat, which in turn is a joint venture between Procter & Gamble and Powerma, a wireless charging technology companyt joint venture, has a relatively excellent comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.
Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. The principle of fast charging of mobile phones is to increase the input of charging voltage or currentBe worth. However, in order to truly realize fast charging of mobile phones, it also needs supporting circuits and hardware.
At present, there are four mainstream Wireless charging standards on the market: Qi standard, Power Matters Alliance (PMA) standard, Alliance for Wireless Power (A4WP) standard, iNPOFi technology. The Qi standard, developed by the Wireless Charging Alliance (WPC), an industry group based in the United States, is used by most mobile phones and electronic devices on the market.
2, the procedure is as follows: Put the mobile phone or device in the support NOn the charger of FC wireless charging, ensure that there is sufficient contact area between the device and the charger. The charger sends an NFC signal to the device, and the device receives and recognizes the signal. The device sends a request to the charger to start charging. The charger will start sending a wireless charging signal to the device, which will receive it and start charging.
3. Yes. According to Sohu, since 2020, smartphones can be charged wirelessly directly through nfc. nfc is near field communication, which supports short distance communication between compatible devices. You need at least one transmission device, and oneReceive the signal.
4, therefore, only mobile phones that support NFC certification can achieve wireless charging, and Huawei mobile phones can not open the NFC function.
5, in the current smart phone basically useful fast charging technology, wired fast charging small 18W, large 50W power, and wireless charging can also reach 30W, NFC is far from meeting the mobile phone charging requirements. NFC wireless charging is not to charge the mobile phone, which has little impact on mobile phone charging.
