The technology, dubbed "Mi Charge Turbo", can charge a 4,000mAh battery from zero to 50 percent in about 25 minutes, and from zero to 100 percent in 69 minutes, claimed the company. They'll also release a 20W smart wireless charging pad that shows the time and charging level. Xiaomi's upcoming second 5G smartphone, the Mi 9 Pro 5G will be equipped with this technology.
At the event, Xiaomi also confirmed that it's working on a 40W wireless charging system but shared no details on how it plans to achieve it. Another thing that Xiaomi announced was that the company is now working on 40 W wireless charging tech too.
The technology uses a 5-layer nanocrystal receiver coil with a conversion efficiency of 98%. Thanks to this tech, you can charge Bluetooth headsets, electric toothbrushes, smartwatches, smartphones, and various other devices which support wireless charging. Again, we are talking about wireless charging here, not wired. The Mi 9 got 20W. In contrast, Xiaomi's 100W technology was slightly faster and managed to charge a bigger, 4000mAh battery, in 17 minutes. Xiaomi says future smartphones with Mi Charge Turbo support will be able to charge others phones, accessories, earphones and wearables wirelessly.
As for the 40W wireless charging, the company says that the technology has entered the testing phase, so we can expect to see it powering some smartphone by the end of the year or early next year. This should also help to keep the temperature under control. It's forming a wireless charging alliance to standardize things.
The upcoming Mi 9 Pro 5G will support four types of charging: wired fast charging, wireless flash charging, wired reverse charging and wireless reverse charging.
