OREANDA-NEWS. March 15, 2016. For the three months ended January, the iPhone took home a smartphone market share of 25 percent in urban China, research firm Kantar Worldpanel ComTech said. Though that number helped Apple keep its top spot, the rate of growth was just 1 percent higher than the same quarter a year ago and was the slowest since late 2014, according to Kantar.

Why the slowdown in sales growth?

"Looking at the three months individually, January was the weakest month for Apple in China as more price-sensitive consumers might have been waiting to see what promotions Chinese New Year would bring in early February," Carolina Milanesi, Kantar chief of research, said in a statement.

But Apple is also facing an ailment known as phone fatigue: New models are lacking must-have features needed to get us to upgrade and we're already pretty satisfied with the models we're using. Android phone makers such as Samsung have been hit by the same problem. But specific to Apple, a lack of new features in last year's iPhone 6S and 6S Plus took a toll on sales not just in China, but around the world.
