From 5W to 120W And From 7.5W to 50W: Development of Xiaomi Charging in Ten Years

Earlier Xiaomi released the Mi 10 Ultra, which supports 120W wired charging + 50W wireless charging + 10W wireless reverse charging. Today, the company, officially, summarized the development of Xiaomi charging technology in the past 10 years.

Xiaomi Charging: Wired

• In 2011, the first generation of Xiaomi smartphones was using 5V1A 5W charging.
• In 2013, the Mi 3 adopted the integrated non-removable battery + Quick Charge technology QC 2.0 for the first time, with an optional 10W (5V2A) fast charging head. It reduced the charging time by 30%. According to the official introduction, starting from the Mi 3, Xiaomi has officially made a layout for fast charging.

• In 2015, the Mi 5 adopted QC 3.0. With the support of dual Charger parallel charging technology, the charging rate of the Mi 5 was increased by 20%. And the maximum charging rate was 18W. The three generations of products from the Mi 5 to the Mi 8 all used 18W fast charging.

• In 2019, the Mi 9 increased the charging power to 27W for wired charging, with a 27W power adapter as standard, and supported QC 4 + fast charging protocol. It is the first time to adopt the charge pump charging technology of half-voltage direct charging and has passed the TÜV Rheinland safety fast charging certification.

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

• The 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. Its built-in butterfly double-string batteries, equivalent to 4500mAh, can charge to 41% in 5 minutes, and get full in 23 minutes. This also makes it the first mass-produced smartphone that supports 120W charging.

Xiaomi Charging: Wireless

• At the beginning of 2018, the Xiaomi Mi MIX 2S supported 7.5W wireless charging for the first time. This made the phone the first smartphone in China that supports wireless charging. The Mi MIX 3 released in October of the same year upgraded the wireless charging power to 10W.

• The Xiaomi Mi 9 released in early 2019 supports the fastest 20W wireless charging at the time and passed the Qi EPP certification of the WPC Wireless Charging Alliance.

• The Mi 9 Pro released in the second half of 2019 supports 30W wireless charging. The latter can charge the 4000mAh in 69 minutes.

• The Xiaomi Mi 10 series released in early 2020 continued to use a 30W wireless charging technology. The Mi 10 Pro can charge a 4500mAh battery to 100% in 65 minutes.

• The newly released Mi 10 Ultra supports 50W wireless charging. It can charge a 4500mAh large battery to 100% in 40 minutes.

• In addition to 50W wireless charging, the Mi 10 Ultra also uses a new customized charge pump + a newly designed butterfly dual-cell series structure design. It improves charging efficiency and charging power. The butterfly packaging method also makes the battery capacity further increase.

The fast-charging system of Xiaomi’s new flagship will break through again next year. The current wired + wireless + reverse of the laboratory test can reach more than 200W.
