iOS slips due to iPhone's higher price tag.
Android continued to dominate the Chinese smartphone market, with the Google mobile operating system increasing its share during the third quarter.
In the period, Android attributed to 90.1 percent of China's smartphone market, representing an increase from the 83 percent share it had during the second quarter.
According to Beijing-based research firm Analysys International, Apple's iOS settled for a distant second with a 4.2 percent hold, a decrease from the 6 percent share it had in the second quarter. Symbian, meanwhile, saw its market share drop to 2.4 percent.
Apple struggles in China as the iPhone retails for a much higher price than its Android-powered device counterparts. The iPhone's average cost is 3.25 times higher than that of the average Android smartphone sold in the region.
Overseas, Android is also experiencing a stronger grip on the smartphone market, with the platform accounting for 72.4 percent of all smartphones sold during the third quarter.
