Today, Xiaomi released its self-developed “Mi Air Charge” technology and published a poster. This technology does not require a base, and long-distance wireless charging can be achieved whether in the hand or in the pocket. Xiaomi Mi 11 is the first phone to implement this technology. Before Xiaomi released this technology, Motorola today also publicized its wireless charging technology and released a demonstration video.
It can be seen in the video that, unlike Motorola’s technology, Xiaomi’s air charging technology is not affected by objects. The official said that there is no need to put the phone in a fixed position, and it can be charged wirelessly from a long distance when playing in the hand or in the trouser pocket.
Xiaomi introduced that air charging is realized through Xiaomi’s self-developed air charging pile, which has 5 built-in phase interference antennas, which can position the mobile phone in millisecond space and accurately detect the position of the mobile phone. The phase control array composed of 144 antennas can transmit millimeter-wave to mobile phones through beamforming, and the mobile phone can receive it through the micro beacon antenna, which can realize 5W long-distance charging within a few meters. Xiaomi owns 17 technical patents for the Mi Air Charge.
It is reported that Xiaomi’s self-developed Air Charge technology can also charge smartwatches, bracelets, and other wearable devices. In the future, the living room, including speakers, desk lamps, and other small smart home products, can realize wireless power supply design, completely get rid of the shackles of wires, and truly realize wireless living room. More importantly, the mobile phone can be charged wirelessly at a long distance, no matter in the hand or pocket, without cable or base. Charging while playing, multiple devices charging at the same time, even if it is blocked by objects.
