In a recent video posted on Weibo, Xiaomi has showcased its 40W flash wireless charging technology which can charge 0-100% in 40 mins.

Wireless charging tech on smartphones has been around for quite a while now. However, unlike other innovations in the smartphone world, wireless charging hasn't caught up. While this low rate of adoption can be attributed to several reasons, there's one major issue that has limited the spread of wireless charging on modern smartphones — slow charging speeds. At a time when a wired charging connection can, most likely, get your smartphone from 0-100% in just about an hour, most wireless charging solutions on premium flagships can barely match that performance.

In a bid to address this issue, several smartphone manufacturers have been working on more powerful and efficient wireless charging tech. For instance, earlier this year Xiaomi launched its Mi 10 flagship lineup in China, which features support for 30W fast wireless charging. The Mi 10 lineup was one-upped by Vivo's APEX 2020 concept, which features support for 60W fast wireless charging. According to the company, the 60W wireless charging solution is capable of charging a 2,000mAh battery in just 20 minutes. But since the APEX 2020 is just a concept smartphone, we can't expect its Super FlashCharge technology to make it to production devices anytime soon. Xiaomi, however, might bring a 40W fast wireless charging solution to its devices sometime later this year.

In a recent post on Weibo, the company's co-founder Lei Jun revealed the company's new wireless flash charging technology which boasts of 40W output capabilities. As seen in the video above, the new fast charging technology can charge a 4,000mAh battery from 0-57% (2,280mAh) in just 20 minutes, while taking about 40 minutes to get it up to 100%. In effect, this makes Xiaomi's wireless flash charging technology faster than Vivo's 60W Super FlashCharge. While it would be great to see this new technology in an upcoming Xiaomi device, the company hasn't revealed any information about the release timeline for the same. It's also worth noting that the phone in the video is a prototype/custom Mi 10 Pro.
