Nearly 1 billion smartphones will be shipped globally in 2015, almost double the amount for all of 2011, as millions of people seek out the more powerful mobile phones that are dropping in price, market research firm IDC said.
"The smartphone floodgates are open wide," IDC analyst Kevin Restivo said in a statement today.
The IDC forecast puts Android smartphones from several manufacturers on top from 2011 throughout 2015, with nearly 44% of the global smartphone market in 2015, up from 39% in 2011. Android first hit the top position globally in the fourth quarter of 2010, IDC noted.
In 2015, Windows Phone is expected to be in second place with a 20% share, growing from less than 4% in 2011.
Symbian drops out of the picture by 2015, down from its 20% share in 2011. Microsoft has partnered with Symbian maker Nokia on the Windows Phone OS, which will supplant Symbian in later years, IDC said.
The predictions of Windows Phones' ascendancy raised some eyebrows when IDC first made that prediction, but Gartner also shared that view. Both analyst firms have noted that Nokia has superior manufacturing and distribution capability, and is expected to produce its first Windows Phones on the Mango version of the OS late in 2011.
While both the iPhone and the BlackBerry will see a modest shrinkage in market share in the next four years, IDC noted that both will still see growth in shipments and sales coinciding with the explosive growth in smartphones.
In 2011 alone, vendors will ship about 472 million smartphones, about 55% above the 305 million shipped globally in 2010. IDC said 982 million smartphones will ship in 2015.
Smartphone growth is being fueled by falling average selling prices, increased phone functionality and lower cost data plans, IDC said. Many of the most powerful smartphones in the U.S. market are selling for $250 to $300, well below prices in the $300 to $400 range of two years ago.
Some smartphones released this year have new features such as video chat and more powerful 1.2 GHz dual-core processors that can enable faster real-time multiplayer game play and video replay in high definition.
