Xiaomi lets smartphones charge wirelessly… remotely – News

The Chinese tech giant Xiaomi has developed a new technology to charge smartphones wirelessly. The special thing about Mi Air Charge is that charging is done remotely and not via a ‘charging plate’. Even when you use the phone or have it in your pocket, the battery is refueled.

Wireless charging of smartphones is rapidly gaining popularity. The gadget is no longer only reserved for the expensive top models, and more and more cars also have a place where you can recharge your phone without cables. The required wireless charger – say: the charging plate – is now also integrated in all kinds of other devices, ranging from table lamps to bedside tables.

Remote charging

The innovative thing about the Mi Air Charge technology is that there is no longer any need for physical contact between the smartphone and the wireless charger. Xiaomi has developed a remote charging charging station with special antennas that can wirelessly charge your phone over a distance of ‘a few meters’.

The charging power of Mi Air Charge is 5W. Compared to the current generation of wireless chargers, that’s not much: last summer Xiaomi introduced the Mi 10 Ultra smartphone that reaches 50 watts (read: wireless charging ten times faster) and just showed a successor to the technology that refuels at 80W. This means that these wireless solutions are even daring with the wired chargers of top phones such as the Huawei P40 Pro+ (40W) and OnePlus 8T (65W), which are given names such as SuperCharge and Warp Charge.

Still, the relatively limited charging capacity of Mi Air Charge does not seem to be a problem. After all, the big advantage is that the smartphone is constantly charged, as long as the device remains somewhat in the vicinity of the remote charging charging station. At home or at the office, by the end of the morning, you constantly have a fully charged battery, without you having to do anything for it. Better yet: you can continue to use the smartphone, walk around with it freely, while Mi Air Charge continues to add fresh energy in the background.

Five gadgets at once

Mi Air Charge does not randomly send the energy waves in all directions, but uses it for this beamforming. Thanks to integrated antennas, the charging station knows exactly the position of the smartphone, which means that very targeted and direct ‘charging waves’ can be sent to the phone (watch the video below this article for more technical details).

The first version of Mi Air Charge can charge up to five smartphones simultaneously (fully) wirelessly, although the capacity of 5W is distributed over all those devices. In the near future, Xiaomi claims, the technology will also be able to be used for other gadgets, such as smartwatches, smart bracelets and other wearables. Further in the future, the company is also thinking of wirelessly rechargeable speakers, desk lamps and other smart home equipment.

When Mi Air Charge will be released on the market, which smartphones are compatible with it and what the technology will cost, Xiaomi has not yet announced.
