If you thought wireless charging is much slower than using cables, then you haven’t been paying attention. Xiaomi has just announced that its achieved 80W wireless charging capable of filling a 4000 mAh battery to 10% in 1 minute, 50% in 8 minutes and 100% in just 19 minutes. The company says it’s spearheading this trend “by recognizing the importance of battery life and faster charging for the future development of smartphones”.
Xiaomi isn’t the only one pushing the frontiers of wireless charging. In July, Chinese smartphone vendor Oppo also announced 65W AirVOOC wireless flash charger along with a 125W wired charger. The 65W AirVOOC wireless flash charger which can fully charge a 4000mAh battery in 30 minutes uses charge pump technology and parallel dual-coil design to further increase wireless charging efficiency.
Xiaomi’s 80W wireless tech follows the 40W wireless charger it announced at first quarter of the year and 50W mast-produced version in August. The recently announced Mi 10 Utra smartphone ships with this 50W wireless charger as well as 120W wired charging option.
This follows recently announced iPhone 12 which supports upto 15W wireless charging with its new line of MagSafe chargers. Compared to the competition, Xiaomi and Oppo have an upper hand as we you can see below.
- OnePlus 8 Pro – 30W wireless charging
- iPhone 12 – 15W wireless charging
- Samsung Galaxy S20 – 12W wireless charging
- Pixel 5 – 18W Qi wireless charging
Even though standard wired charging still out-performs Wireless charging, it has come a long way. Qi wireless charging standard is by far the most popular protocol used by most smartphone vendors and accessory manufacturers, but proprietary options from Apple, Xiaomi and Oppo offering way faster charging speeds for their flagship devices are popular. Good news is that these proprietary products also maintain compatibility with Qi standard meaning your 80W Mi wireless charger can still charge non-Xiaomi smartphone with wireless charging support albeit at slower speeds.
