Chinese smartphones manufacturer Xiaomi Corp said on Tuesday it sold 7.03 million Xiaomi mobiles phoness in the first half of this year and realized unaudited revenue of 13.3 billion yuan 2.16 billion U.S. dollars) during the same period.

According to a news release sent to China Daily, Xiaomi disclosed that its half-year revenue in 2013 exceeded the company's 12.6 billion yuan revenue from all of 2012 but it did not reveal the profitability ratio.

The company is on track to reach its annual goal of selling 15 million Xiaomi smartphoness by the end of the year, according to officials from Xiaomi's public relations department on Tuesday.

As of June, Xiaomi had more than 14 million smartphones users on the Chinese mainland, Hong Kong and Taiwan, the news release said.

Lei Jun, founder and chief executive officer of Xiaomi, attributed the good performance to the company's more influential branding, better industry partner support and an improved logistics and warehouse system.

Founded in 2010, Xiaomi has experienced rapid growth. The company launched its first smartphoness in August 2011 and quickly gained market share, beating some traditional mobiles phones giants.

"In the Chinese market, with the exception of Apple and Samsung, if the shipment of one smartphones model exceeds 1 million during its life cycle, it can be described as 'quite successful'," said James Yan, an analyst with the research firm IDC China.

Xiaomi has managed to sell every one of its smartphones models above the 1 million level and is easily ahead of companies such as Huawei Technologies Co Ltd and ZTE Corp in terms of single smartphones shipments, Yan added, pointing out the latter firms have been selling mobiles phoness for about a decade.

Xiaomi is now directly challenging international giants Samsung Electronics Co Ltd and Apple Inc, which both keep single smartphones sales records in China. According to IDC, Apple had sold about 16 million iphoness 4 and 15 million iphoness 4S handsets in China as of March.

Xiaomi's Lei sees Apple as a target to overtake in the future. During a previous interview with China Daily, Lei expressed Xiaomi's ambition to ship more than 100 million smartphoness annually worldwide for each model by 2016.

Apple, based in Cupertino in the , managed to break the 100 million iphoness devices mark in 2012, less than five years since the first iphoness was sold in 2007.

Lei dreams of achieving a similar, or even faster, pace of development.

"I know it is crazy, but we would like to have a try," Lei said last year.

Overall, Xiaomi's smartphones shipments in China, if they are not counted on the basis of single device shipments, are still small. The company even failed to become a top 10 smartphones supplier in China in the first quarter, according to the Beijing-based research firm Analysys International.

Samsung was the top smartphones company after acquiring a 17.3 percent share in the Chinese market in the first quarter, followed by Lenovo with 13.1 percent and Coolpad with 10.3 percent. The country had sales of 75.3 million smartphoness, a year-on-year rise of 141.5 percent, in the first quarter ending on March 31.
