Apple's share of global smartphone shipments declined to 13.2% in the second quarter, while both Android and Windows Phone registered slight increases, IDC said Wednesday.
The decline in iPhone market share can be traced to the lack of a new model since the iPhone 5 came out nearly a year ago, IDC analyst Ramon Llamas said. Earlier this week, IDC reported that the iPad tablet has lost market share for similar reasons.
"Apple's market share was vulnerable to product launches from the competition," Llamas said in a statement. "But with a new iPhone and revamped iOS 7 coming out later this year, Apple is well-positioned to recapture market share."
All is not so bad for iPhone, however, as total shipments increased by 20% to 31.2 million iPhones in the second quarter over 26 million in the second quarter of 2012. Still, iOS slipped from 16.6% of the market a year ago to 13.2%.
A sales surge by all kinds of Android smartphones weighed on the iPhone.
Android shipments totaled 187.4 million in the second quarter, a 73% increase over the 108 million shipped in the year-earlier quarter, IDC said. That meant Android took nearly 80% of the smartphone market in second quarter, up from nearly 70% in second quarter 2012.
For all smartphone platforms, there were 236.4 million units shipped in the second quarter, up 51% over the 156 million shipped in second quarter of 2012.
Samsung was the largest of the Android manufacturers, accounting for 39% of all Android smartphones shipped -- 73.3 million of 187.4 million. Samsung launched its Galaxy S4 in the second quarter.
The other Android makers, including LG, Lenovo, Huawei and ZTE, each have between 5.4% and 6.5% of the market.
Windows Phone saw the largest percentage gain in Q2 shipments of all smartphones, year-to-year, 77.6%. There were 8.7 million Windows Phone devices shipped in the second quarter, up from 4.9 million in the second quarter of 2012.
Still, Windows Phone holds just 3.7% of the total smartphone market, which is ahead of BlackBerry for the second quarter in a row. BlackBerry's 2.9% share is the lowest level since IDC has been tracking the company's devices.
Nokia was behind the success of Windows Phone, having introduced two new smartphones sold by many mobile operators around the world. Nokia is responsible for nearly 82% of all Windows Phone shipments.
While it was too late to be reflected in the second quarter results, Nokia announced the Lumia 1020 on Windows Phone 8 last month, complete with a 41 megapixel camera and 6x zoom.
