Mi MIX2S is a flagship phone released by Xiaomi in March, and it is also the first Xiaomi phone to support wireless charging.
As of December 12, 2019, HUAWEI has the following mobile phones supporting wireless charging: HUAWEI Mate 30 5G, HUAWEI P30 Pro, and HUAWEI Mate 20 Pro (UD), HUAWEI Mate RS Porsche design.
On the new flagship Mi 10, there is a 30W wireless flash charge function, which increases the power of the minute, and there is a 10W fast wireless backcharge, which means that the Mi 10 can be charged for other mobile phones that need to be charged.
Mobile phones that support wireless charging are: Xiaomi Samsung S10 series, Mi MIX2S, Nut R Mi MIX2S, Huawei Mate20PRO Mi 9 Mi 9The phone was released on February 20, 2019, and in addition to the Qualcomm 855 chip, this product has made leaps and bounds in wireless charging. The Mi 9 mobile phone is equipped with the world's first 20W wireless flash charge, which is comparable to the wired fast charge.
Mobile phones that support wireless charging are: Huawei Mate 40E Pro, Huawei P50 Pro, Huawei Mate 40E, Huawei Mate 40 Pro, Huawei Mate 30 Pro, Huawei Mate 20 Pro, Huawei P40 Pro, etc.
When the LED light status of the millet wireless charger and Millet wireless charger (universal fast charging version) is green and blinking, the millet wireless charger is in the error and protection stage. At this time, you should pay attention to whether there is a metal object placed on the wireless charger, please remove it and charge it again.
Plug the plugged data cable into the millet phone, when the normal indicator light does not respond or flash. At this time, open the back cover and take out the battery, as shown in the figure (the data cable is still plugged in). If the screen displays a startup interface at this time, the charging is successful, and the battery can be charged normally, and the indicator light flashes slowly for normal charging. ifIf no, remove the battery again. Normally, the battery is successfully removed once, usually no more than 3 times can be successfully removed.
Xiaomi9 Two charging methods measured: wired fast charge, half an hour to 61%. 0-100 takes only 63 minutes. Wireless flash charge to 55% in half an hour. 0-100 takes 74 minutes.
Xiaomi mobile phone fast charge can generally pull down the notification bar, find the "wireless charging" icon switch, long press, you can enter the wireless charging setting operation.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
Electric field coupled wireless charging, the principle is by coupling two groups of asymmetries in a vertical directionA dipole generates an induced electric field to transmit electricity. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power. At present, only static wireless charging can be achieved, but static wireless charging is only a little more convenient than wired charging, and it is far less than wired charging in terms of cost, safety and charging efficiency. In terms of technology and cost control, dynamic wireless charging is difficult to popularize in a short time. The reason why there are few models of electric vehicles that support wireless charging today is that the fundamental reason is staticThe practicality of wireless charging is poor.
