The leaked post suggests that Xiaomi will soon be launching a 200W fast charging flagship smartphone.
Q. Is Mi Air Charge harmful to health?
They also discussed the moment in which the charger was covered with a hand, after which the charging process was immediately stopped. You will use the phone while charging since there are no cables or accessories involved to interrupt or not necessarily to stick to the same place to use the phone during charging. Today's Xiaomi announcement does not include vague promises about how long it will take for the company to make its Mi Air Charge technology available outside of its I laboratories.+Dr. Nonetheless, the technology is pretty exciting and offers a glimpse of a much more convenient wireless charging future.

Xiaomi has today revealed its "Mi Air Charge Technology", which is able to wirelessly charge devices from across a room with 5W of power.
We're excited to bring you the remote charging technology - Mi Air Charge Technology! The Mi Air Charge is a new product category with remarkable features.
Xiaomi also explains that it is possible to charge multiple smartphones (5 watts each) at the same time.
While this sort of technology has been proposed and created since the early 20th century by Serbian-American inventor Nikola Tesla through his famous "Tesla coil", there has been limitation to its practical usage, especially in regards as to how air is not that good of a conductor for electricity.
How does this technology work?Inside there are five phase interference antennas, which are tasked with locating your smartphone in the room. A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
For the smartphone, Xiaomi also designed and built a miniaturized antenna array that carries a "beacon antenna" and "receiving antenna array". This is done through something called the rectifier circuit.
This is another very important question that many may ask. As Xiaomi says, Science fiction turned reality.
Currently, the technology allows charging at 5 watts from a distance of several meters. This is hardly enough to cause any harm over the short term. It can charge multiple phones at the same time and at 5W charging speed each.
In addition, walls and other physical obstacles won't diminish its charging power. To show how this might work in the future, the company built a mock living room that contained a smartphone, a lamp, a remote control auto and a fan.
