Apple’s declining streak in China has come to an end, as shipments grew 40% from 8 million in Q3 2016 to about 11 million this quarter. This makes it Apple’s best performance in China in the last eight quarters, where its growth has slowed considerably since the launch of the iPhone 6S. The mix of the iPhone 8 series at launch is also higher than the corresponding mix of the iPhone 7 series at launch last year.

But:

“Apple’s growth this quarter is only temporary. The high sell-in caters to the pent-up demand of iPhone upgraders in the absence of the iPhone X. Price cuts on earlier models after announcing the iPhone 8 have also helped. However, Apple is unlikely to sustain this growth in Q4,” said Canalys Research Analyst Mo Jia.

And:

Despite being touted as widely expensive, excitement for the launch of the iPhone X is building in China.

Good info.
