Xiaomi unveiled its "Mi Air Charge Technology", a technology capable of charging wirelessly the devices from the whole room with 5W of power.
Mi Air Charge technology offers a "true wireless charging solution," the company says, without cables or stands. The devices charge remotely with 5W of power.
How Xiaomi's remote wireless charging works
Xiaomi's remote wireless charging unit uses a space positioning system and transmits energy with the technology beamforming.
Mi Air Charge uses five-phase interference antennas, able to accurately detect the position of a smartphone. Once its location is located, a 144-antenna phase control array transmits remote wireless charging directly to the phone via beamforming millimeter waves.

For smartphones, the system is run in
Xiaomi has also developed a reception system, miniaturizing and integrating another array of miniaturized antennas into its smartphones. These antennas they transmit the position of the phone and convert millimeter waves into electricity for remote wireless charging of the mobile phone.
It can charge multiple devices and knows no obstacles
The wireless remote charging technology is capable of charging multiple devices within a range of several meters, with each device capable of receiving 5W of power. Xiaomi also notes that physical objects placed between the charging battery and the device do not reduce charging efficiency.
And now?

Xiaomi says it is looking to expand remote wireless charging technology to other devices as well. Potentially tons of it: Smartwatches, bracelets and other wearables, as well as smart home speakers, desk lamps, and more in the future.
It's unclear how close Xiaomi is to bringing its Mi Air Charge technology and wireless charging battery to the consumer market, but today's reveal may suggest it's very close.
