However, it is from the mass consumers that Xiaomi has benefited the most in the global market. According to IT research firm Gartner, for the fourth quarter of 2014, "out of all of the global smartphone makers, Xiaomi saw the largest jump by tripling its sales compared to a year ago."

Xiaomi shipped 18.6 million smartphones in the 4th quarter last year, behind homeland competitor Lenovo's 24 million and Huawei's 21 million.

Meanwhile, Apple sold 74.8 million iPhones, slightly higher than Samsung's sales of 73 million smartphones. Apple had become the world's largest smartphone manufacturer again.

The reason why high-priced iPhones sell the best is because their high quality, according to Wang Guanxiong, an Internet analyst.

Nevertheless, industry experts believe Chinese smartphone makers are narrowing the gap with foreign giants.

"China is doing well on home-grown smartphone core technologies including chips and operating systems. Xiaomi, Huawei and Alibaba invested huge on operating systems. Home-made smartphone makers depend less and less on foreign giants," said Ni Guangnan, a member of the Chinese Academy of Engineering.

Huawei spends 10 percent of its revenue on research and development(R&D) each year. Xiaomi never published its R&D spending. Apple spent nearly $2 billion on research and development in the first fiscal quarter of 2015, an increase of 42 percent year on year.
