In its latest forecast, IDC has also claimed that Microsoft will report a year-over-year decline of 10.2 percent this year followed by further decline next year. The company attributed the decline in number to the lack of OEM partners with Microsoft.
"Despite all the effort Microsoft has put into the launch of Windows 10 [Mobile], IDC does not expect Microsoft's share of the smartphone OS market to grow much over the coming years," said IDC in its forecast.
The company added that Microsoft is expected to keep the average selling price (ASP) of Windows Phones around $148 (approximately Rs. 9,900) in 2015 which it claims is $71 (approximately Rs. 4,750) lower than Android's ASP of $219 (approximately Rs. 14,700).
IDC also details the era when Microsoft and Nokia jointly launched phones in low-end segment which saw the rise in shipments of phones to 34.9 million in 2014.
The company compares its forecast for 2015 which claims that Windows Phones this year will see a shipment of 31.3 million units with 2.2 percent market share compared to 226 million units of iOS devices with market share of 15.8 percent, and 1,161.1 million units of Android devices with 81.2 percent. For 2019, IDC expects Windows 10 Mobile (or the equivalent version at the time) shipments to increase to 43.6 million units with marginal increase in market share to 2.3 percent.
In its forecast, the company also claims that this year, the smartphone segment will see a single-digit increase to 9.8 percent with a total of 1.43 billion units shipped.
"With the smartphone market finally slowing to single-digit growth, maintaining momentum will depend on several factors. The main driver has been and will continue to be the success of low-cost smartphones in emerging markets. This, in turn, will depend on capturing value-oriented first-time smartphone buyers as well as replacement buyers. We believe that, in a number of high-growth markets, replacement cycles will be less than the typical two-year rate, mainly because the components that comprise a sub-$100 smartphone simply do not have the ability to survive two years," said Ryan Reith , Program Director with IDC's Worldwide Quarterly Mobile Phone Tracker.
