Microsoft recently launched a mobile IE9 testing site that allows web developers to test the HTML5 abilities of Windows Phone Mango
Last month the software giant Microsoft demoed the Mango update with 500 new features, including a mobile version of Internet Explorer 9. In a preview video, Microsoft vice president Joe Belfiore ran a test between phones running Windows Phone 7, Android, BlackBerry OS and iOS and declared Windows Phone the winner. Microsoft’s device rendered HTML5 content at 24 frames per second, compared to 2 frames per second on the iPhone 4 and 11 FPS on the Android Nexus S device.
But what about an iPhone 4 running the beta release of iOS 5? As noted by winrumors, it has reached 31 frames per second on the test. However, a screenshot demonstrating the test results still lists the iOS 4.3 version of Mobile Safari.
Windows Phone 7 and iOS 5 are both scheduled for a fall release, though Microsoft and Apple have yet to set specific release dates.
Apple unveiled iOS 5 earlier this month at the WWDC with over 200 new user features and 1500 APIs.
Meanwhile, Microsoft has teamed up with Nokia, reportedly paying billions to Nokia in exchange for the company’s commitment to Windows Phone 7. In February, Nokia announced plans to ditch its Symbian mobile operating system and begin making smartphones running Windows Phone. Nokia confirmed last month that the first of its devices to run Windows Phone 7 will feature the Mango update.
Research group IDC predicts the Microsoft and Nokia partnership will help boost Windows Phone market share from 3.8 percent in 2011 to 20.3 percent in 2015, while Apple’s share of the worldwide smartphone market is expected to dip from 18.2 percent to 16.9 percent during the same period.
