Demo model: MI 11 System version: MIUI 11 Slide down from the top of the phone screen to bring up the control panel, and continue to pull down to expand the full function of "Control Center". In the Control Center screen, swipe left to the last page. Click the Edit button. Click the wireless reverse charging button. When the button turns blue, it is on.
In the Control Center screen, slide to the leftThe last page. Click the Edit button. Click the wireless reverse charging button. When the button turns blue, it is on. Mi 11: The Mi 11 is a mobile phone owned by Xiaomi Corporation, which was released at Xiaomi Science Park on December 28, 2020 and will be available on January 1, 2021.
First, we need to confirm whether our millet 11 supports wireless charging function. You can view this information in your phone's Settings. Enter "Settings" - "Battery and Performance" - "Wireless charging", if the "wireless charging" option appears, it indicates that the device supports wireless charging. After confirming that the device supports wireless chargingWe need to prepare a wireless charger that supports the Qi standard.
Mi 11 The steps to enable wireless charging are as follows: In the phone Settings menu, click "Save power and battery". Open Wireless Reverse Charging on the Battery page. Just put the phone back to back with the device that needs to be charged.
Applicable brand model: Mi 11; System: miui15; Connect the data cable to the wireless charger, then plug it in, and plug it in. Then place the Mi 11 phone in the center of the wireless charger, and it will show that the phone is charging. When fully charged, remove the plug from electricityHow does it work? What is the farthest distance?
1, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge.
2, radio waves. The principle is to convert environmental electromagnetic waves into current and transmit current through a circuit. This way the transmission distance is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. WiFi wireless charging. It mainly consists of two components, one is the Wi-Fi access point (router), and the other partThe points are customized charging sensors.
3, the principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
4, the principle is very simple, that is, electromagnetic induction, but the actual wireless charger must be more complex, because it needs supporting program functions, such as foreign body detection, temperature control, frequency conversion, etc. If you are just experimenting, get two coils of the same size (different is OK, but the voltageWill change), one input 5V AC in, the other connected to the mobile phone charging port can be charged, but the efficiency is certainly very low.
5, wireless charger through the principle of electromagnetic induction for mobile phone charging. A coil on the charging pad converts magnetic energy into electricity, which charges the phone's battery. Wireless chargers are usually made of glass, because glass has a better guiding effect on the magnetic field, which helps to improve the charging efficiency. Wuhan Jianghan Road has installed 60 street lights with wireless charging function, and each street lamp has two charging positions to support high-power charging.
1, millet 11 space charging speed is fast Millet wireless charging distance : At present, millet space charging can only support 5 watts of charging Millet wireless charging distance , want to be full of 4500mAh battery at least 2 to 3 hours. Although the speed is not fast now, there is no need to worry about the later charging power can get rid of the charging trouble after the increase. Air charging can not only be used for mobile phones but also for audio, smart watches and so onThe device is charged.
2, product he is not a universal charger thing Millet wireless charging distance , because even if it can be charged, it can not reach the foot fast charging speed, and then you are using iPhone12, you use iPhone11 charger, If he can charge, do not consider the charging speed problem, after a period of time on the system experience, you find not.
3. Xiaomi's air separation charging technology relies on fine control of spatial positioning and energy transmission. With the built-in 5 phase interferenceThe beamforming array composed of antennas and 144 antennas can position the mobile phone at the millisecond level, and accurately send the millimeter wave to the mobile phone without contact, significantly improving the efficiency and convenience of wireless charging. In 2020, Xiaomi has achieved 80 watts wireless second charging, surpassing the Xiaomi wireless charging distance the speed of wired fast charging.
4. Mi's air separation charging technology is based on spatial positioning and energy transmission technology, using the 5 phases built into the self-developed air separation charging pileThe interferometer antenna performs millisecond positioning, and the array of 144 antennas sends millimeter waves precisely in a directional direction to the phone through beamforming. At present, the technology has achieved 5 watts of long-distance single device charging, and can support multiple devices charging at the same time, even if there is foreign interference, the charging efficiency remains stable.
5, because the energy loss efficiency of this technology is about 70%, but the stable power of 5~10w is the limit.
