It’s not just China’s rich buying iPhones…

Apple has managed to get a foothold in the lucrative Chinese smartphone market with the iPhone 6, but it's not just the country's wealthiest snapping up the devices.

Apple's second-quarter revenue from Greater China—defined as mainland China, Hong Kong and Taiwan—totaled $16.8 billion, a 71 percent year-over-year jump, making it the U.S. technology giant's second-biggest market after the U.S..

On top of that, more iPhones were sold in Greater China than the U.S. during the quarter.

But this growth was driven in part by less well-off buyers.

Apple's huge earnings beat

In the first quarter of this year Apple represented 25 percent of smartphone sales in urban China's 2,000 ($322) to 4,000 yuan ($644) monthly income bracket—a 10.1 percent increase from the same period in 2014, according to Kantar Worldpanel research.

This is surprising given that a 16GB iPhone 6—the cheapest model available—costs 5288 yuan or $851. The starting iPhone 6 Plus model is priced at 6088 yuan or $980.

Apple has struck a chord with consumers in the world's second-largest economy. A recent survey by publishing group Hurun Research showed that iPhones were the gift of choice amongst China's wealthiest and it is seen as an aspirational brand.

Overall in urban China, Apple "consolidated its leadership" in smartphones, growing its market share to 26.1 percent in the first quarter of 2015, up from 17.9 percent for the same period last year, Kantar Worldpanel said.
