Xiaomi has announced that it sold over a million units of the Mi 11 in just 21 days. This comes after selling 350,000 units on the first day, and over 500,000 by the tenth. All of this translates into over US$600 million of revenue from Mi 11 sales alone, with the phone still yet to make its way outside China.
