About Apple’s 40% Share of the U.S. Smartphone Market by Philip Elmer-DeWitt @FortuneMagazine February 11, 2016, 12:33 PM EST E-mail Tweet Facebook Linkedin Share icons The report and accompanying pie chart released Wednesday by Parks Associates in advance of Mobile World Congress celebrates Apple’s 40% share of the U.S. smartphone market, but doesn’t say whether that’s up or down. In fact, it’s down a couple percentage points from 2014. The report released two weeks earlier by Kantar Worldpanel tells a more nuanced story. It distinguishes between Apple aapl , the smartphone manufacturer, and Apple’s iOS, the smartphone platform. Although Apple finished 2015 as the No. 1 brand in both the U.S. and China, iOS has lost share to Google’s goog Android in both markets. To illustrate that last point, here’s Kantar’s data for the last three months of 2014 and 2015 in a pair of interactive bar charts: By switching views from Dec. 2014 to Dec. 2015 you can see that iOS’ share grew in China, but fell domestically. How can this be? Didn’t Tim Cook tell analysts last month that he was “blown away” by the record number of consumers switching from Android devices to iPhones? Get Data Sheet, Fortune’s technology newsletter. Carolina Milanesi, Kantar’s chief of research, suggests that what we’re seeing in the U.S. might be an artifact of smartphone saturation. “The U.S. market continues to be very competitive as smartphone penetration reached 65% among mobile phone users and 84% of overall mobile phone sales,” she writes. “The pool of available new buyers is shrinking and Android’s wider price range helps them grab late adopters looking for their first smartphone.” For more on Apple, watch: Mobile World Congress opens Feb. 22 in Barcelona and runs for four days.
