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.

I have always been very passionately interested in mobile technologies, especially smartphones. Being a tech enthusiast means the half-life of my devices isn’t exactly long, and being the latest hardware is not enough to suffice as the manufacturer and operating system play a minor role – the most important aspect for me is that the device is state-of-the-art. After posting for Mobi Test I joined Notebookcheck in 2016, where I have been pursuing my enthusiasm for technology by reviewing the latest smartphone, tablet, and accessory trends.
I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
