Xiaomi Announces 80-watt Wireless Charging Technology

Mi 10 Ultra

The Chinese manufacturer Xiaomi has made another breakthrough in the field of wireless charging. Android smartphones should be able to be charged wirelessly with up to 80 watts within a few minutes. Only the right end devices are missing until now.

Xiaomi is known for its east trendsetting technologies in the field of power supply for Android smartphones. Models like the Xiaomi Mi 10 Ultra already rely on fast charging methods with 120 watts (via cable) and 50 watts (wireless). In a recently published blog post, the company announced that it will be possible to charge mobile phones with up to 80 watts in the future and that the right technology is in the starting blocks. However, it remains to be seen when this will show up in the first smartphones.

Wireless full charging soon within a few minutes

Xiaomi provides a corresponding calculation example. According to the manufacturer, a smartphone with a 4000 mAh battery is charged from zero to 10 percent within one minute, to 50 percent in just eight minutes, and to 100 percent after a total of 19 minutes. The wireless charging technology introduced by Xiaomi last year with a maximum of 30 watts required 69 minutes for the same process. This year alone, the jump was first made to 40 watts, then 50 watts, and now to 80 watts. It remains to be seen how long-term fast charging will affect the longevity of the battery. The Xiaomi Mi 10 Ultra remains the flagship model. 

The 6.67-inch smartphone supports wired fast charging with up to 120 watts with its 4500 mAh battery, while the permanently integrated battery can be charged wirelessly via wireless charging (Qi) with up to 50 watts. In addition, the Qualcomm Snapdragon 865, up to 16 GB of RAM, a maximum of 512 GB of UFS 3.1 storage, and a 120 Hz OLED display is used. The cameras, however, are equipped with up to 48 megapixels. It is still unclear whether and when the Mi 10 Ultra will reach the European market.
