Apple remains top brand, but iPhone 6s not so hot

Apple Inc remains the most popular smartphone brand in China, despite its recent poor performance in its second-largest market, a new report said.

The report, released by China Mobile Communications Corp, is based on the analysis of the world's largest telecom operator's roughly 800 million subscribers. This is the first time that China Mobile opened its big data report to public.

In May, about 15 percent of China Mobile's subscribers are using iPhones, which amounts to about 120 million users. Domestic brands Xiaomi Corp and Huawei Technologies Co Ltd rank alongside Samsung Electronics Co as the second-most popular brands, with each company accounting for 9 percent of subscribers.
