Today, Xiaomi launched its self-developed Xiaomi Air charge technology and unveiled a poster. This technology does not require a dock and enables wireless charging over long distances, whether you hold it in your hand or put it in your pocket. The Xiaomi 11 is the first phone to implement this technology. Before Xiaomi released this technology, Motorola also announced its wireless charging technology today and released a demo video.
The video shows that unlike Motorola’s technology, Xiaomi’s air charging technology is not affected by obstacles. According to the official statement, there is no need to place the phone in a specific position; it can achieve long-distance wireless charging whether held in hand or kept in a pocket.
Xiaomi stated that air charging is achieved through its self-developed wireless charging station, which uses five phase-interference antennas that can locate the phone and accurately detect its position within milliseconds. A phased array composed of 144 antennas can transmit mmWave to the phone through beamforming, and the phone receives the signal via the micro-beacon antenna, enabling 5W long-distance charging within a few meters. Xiaomi holds 17 patents for Mi Air Charge technology.
It is reported that Xiaomi’s self-developed Air Charge technology can also charge wearable devices such as smartwatches and fitness bands. In the future, small smart home products in the living room, such as speakers and desk lamps, will all feature wireless power designs, completely freeing them from cables and truly creating a wireless living room. More importantly, phones will be able to charge wirelessly over long distances, whether held in hand or kept in a pocket, without the need to connect to a cable or charging dock. You can play while charging, charge multiple devices simultaneously, and it will work normally even if blocked by objects.
