Sales of Windows Phone 7 handsets have been somewhat below Redmond's expectations thus far.
However, Windows Phone unit boss Andy Lees says he believes Microsoft has successfully regained its mojo in the smartphone sphere with Mango.
According to Lees, Redmond is setting its sights on becoming the No. 3 platform by offering a viable alternative to Google's Android and Apple's iOS.
"We're not making specific predictions but I think that our momentum is going to build," Lees told AllThingsD.
"Our first [release] was about mindshare, and really getting the credibility, and I think [Mango] is really about starting to build unit volume and market share."
Lees also confirmed that a number of future Windows Phone handsets would boast dual-core processors along with support for faster LTE networks.
"They're all single core [now], but I suspect that they will be faster in usage than any dual-core phone that you put against it, and that's the point.
"[Regarding LTE], the first LTE phones were big and big users of the battery, and I think it's possible to do it in a way that is far more efficient, and that's what we will be doing... I think our strategy is to put things in place that allow us to leapfrog, and I think that's how we've gone from worse browser to the best browser, and I think the same is true with hardware," he added.
