Xiaomi's fast-charging technology used in the Mi 10 Ultra is a game changer
When it comes to fast-charging technology, no other manufacturer is currently ahead of Xiaomi. The Mi 10 Ultra has a 4,500 mAh battery - to be precise, the Chinese manufacturer installs a 2,250 mAh battery in a dual format, so that the aforementioned capacity is achieved by combining the two batteries.
Fast-charging technologies have been revolutionized in the smartphone segment over the past few years. Early breakthroughs were achieved in the Android segment with 20-watt chargers and later with the nowadays "common" 50-watt or 60-watt power adapters. Xiaomi has now advanced into the triple-digit range, and it looks like a limit is still a long way off.
Xiaomi's flagship already comes with a 120-watt power adapter in the box, and it charges the two 2,250 mAh batteries in less than 25 minutes. We were also able to confirm this manufacturer's claim in the test. Going from 0 to 70% only takes about 14 minutes, which should (theoretically) get most users through the day in view of the Mi 10 Ultra's runtimes of over 12 hours in our WLAN test with an adjusted display brightness of 150 cd/m². For comparison purposes, an Apple iPhone 12 Pro charges at a maximum of 20 watts using a cable.
However, according to reports, Xiaomi's 120-watt charger actually "only" delivers 80 watts to the Mi 10 Ultra, which again suggests that these incredibly fast charging times of the flagship smartphone might soon be significantly surpassed.
Wireless charging is also supported at 50 watts, so that a charge only takes about 45 minutes according to Xiaomi. And Reverse Wireless Charging is also on board, allowing peripheral devices to be charged at up to 10 watts.
