4. In 2019, the Xiaomi Mi 9 increased the charging power to 27W for wired charging. It also came with a 27W power adapter as standard as well as QC 4+ fast charging protocol. This was the first time when a smartphone adopted the charge pump charging technology of half-voltage direct charging. Also, it has passed the TÜV Rheinland safety fast charging certification.

The Mi 9 Pro released in the same year supports 40W wired charging. It came with a standard 45W power adapter, which can charge a 4000mAh battery in 48 minutes. The power adapter is compatible with the PD protocol. Thus, it is convenient for charging laptops and other devices that support the PD protocol.

5. The Xiaomi Mi 10 Pro released in February 2020 increased the charging power to 50W, which can charge a 4500mAh battery in 45 minutes.

The newly released Mi 10 Ultra uses a 120W wired charging and comes with built-in butterfly double-string batteries that are equivalent to 4500mAh. They can be charged 41% in 5 minutes, and be fully charged in 23 minutes. This also makes it the first mass-produced smartphone that supports 120W charging. The 50W wireless charging supported by it can be used to fill the phone in 40 minutes.
