Lei said 2.15 million models have been sold in a single month, this despite the overall challenge the company has faced trying to sell its smartphones in 2015.
“We prepared our largest inventory to date for the Redmi 2, “ he wrote on his Weibo account with a smiling emoji.
The Redmi 2 was launched last month at the price of RMB 799 (US$127) with over 800,000 units sold on its first day, the company said.
The model sold more than 1.5 million units in two weeks and has achieved a new monthly record.
Sales of the Redmi 2 have been a breakthrough for Xiaomi, a company which has seen its half-year 2015 sales fall below amounts from the previous year.
Xiaomi said it sold 34.7 million smartphones in total for the first six months of this year. That number was at 36 million last year.
Xiaomi’s foreign rival, Apple, topped the Chinese smartphone market in the first quarter, helped by demand for the new iPhone 6, Kantar Worldpanel ComTech’s report said in May.
“Consumer expectations for Xiaomi are too high,” Lin Bin, Xiaomi’s co-founder and president, told Tencent Tech.
“It’s impractical for us to make another 200% increase on our current performance, we’d need to sell another 150 million units.”
