  • WM 5.0 featured increased battery life due to Persistent storage capability. Previously up to 50% (enough for 72 hours of storage) of battery power was reserved just to maintain data in volatile RAM. This continued the trend of Windows-based devices moving from using RAM as their primary storage medium to the use of a combination of RAM and flash memory (in use, no distinction between the two is obvious to users). Programs and frequently accessed data run in RAM, while most storage is in the flash memory. The OS seamlessly moves data between the two as needed. Everything is backed up in the flash memory, so unlike prior devices, WM5 devices lose no data if power is lost.

The most apparent of the other differences is that the Standard version (like prior versions) still creates automatic links for telephone numbers in Tasks and Appointments, which allows for the easier click and dial of stored telephone numbers within these Outlook items. This feature is not supported in the Professional version. Windows Mobile 6.1 also had improved bandwidth efficiency in its push-email protocol "Activesync" of "up to 40%"; this considerably improved battery life in many devices.

Aside from the visual and feature distinctions, the underlying CE versions can be used to differentiate WM6.0 from WM 6.1.

Windows Mobile 6.5.3 brings a more finger-friendly user interface with several new usability features such as support for multitouch, complete touch control i.e. no need for a stylus, and drag-and-drop start menu icons. Touchable tiles replaced soft keys." Internet Explorer Mobile 6 has also received some major updates including decreased page load time, improved memory management and gesture smoothing.

Additional features of newer Windows Mobile 6.5.3 builds include threaded email and Office Mobile 2010.

Windows Mobile 6.5.5

Several builds of Windows Mobile 6.5.x leaked since January 2010, and were unofficially ported to some Windows Mobile phones. The name Windows Mobile 6.5.5 has been applied to these newer builds, although this name remains unconfirmed by Microsoft.

Windows Embedded Handheld 6.5

On 10 January 2011, Microsoft announced Windows Embedded Handheld 6.5. The operating system has compatibility with Windows Mobile 6.5 and is presented as an enterprise handheld device, targeting retailers, delivery companies, and other companies that rely on handheld computing.

Windows Phone

Windows Phone was launched in Europe, Singapore, and Australia on October 21, 2010, and in the US and Canada on November 8, 2010, with the rest of the world to follow in 2011. Microsoft had originally planned to continue the Windows Mobile line to Windows Mobile 7, based on an upgrade to the Windows Mobile platform, codenamed Photon. The original Photon and Windows Mobile 7 have since been scrapped; however, Microsoft decided to create a new mobile OS platform and officially announced Windows Phone 7 Series in its place. Microsoft has since renamed the operating system from Windows Phone 7 Series to Windows Phone 7.

Windows Phone was initially intended to be released during 2009, but several delays, likely due to the move away from Photon and to building an entirely different and new platform, prompted Microsoft to develop Windows Mobile 6.5 as an interim release. During the Mobile World Congress 2010 in Barcelona, Microsoft revealed details of Windows Phone, which features a new operating system and integration with Xbox Live

 research data showed that while the total smartphone industry grew 27% between 2008 and 2009, Windows Mobile's share of the smartphone market fell 2.7% in that same period.

In 2004, Windows Mobile accounted for 23% of worldwide smartphone sales. Windows Mobile was projected to overtake Symbian to become the leading mobile OS by 2010. But by 2008, its share had dropped to 14%. Microsoft licensed Windows Mobile to four out of the world's five largest mobile phone manufacturers, with Nokia being the exception.

Although Microsoft apparently has 50 handset partners, 80% of the 50 million Windows Mobile devices made have been built by one contract manufacturing group, HTC, which makes handsets for several major companies under their brands, and under its own brand.

Possible trends

From late 2009 many industry analysts and media reports began to express concerns about the future viability of the Windows Mobile platform, and whether Microsoft would keep supporting it into the future.

 could be "the last throw of the dice."

In August 2009, analysts J.Gold Associates predicted in BusinessWeek that Microsoft would probably exit the mobile operating system market sometime between 2010 and 2011.

The New York Times reported in 2009 that Windows Mobile "is foundering", as cellphone makers desert it in favor of Google's Android phone platform. It cited the difficulties in Microsoft's business model, which involves charging handset manufacturers up to $25 for each copy of Windows Mobile, while rival Google gives away Android for free.

The Washington Post said Windows Mobile is "bleeding market share in the space, and the future looks grim." It said that Google is using Android to "kill" Windows Mobile.

In February 2010, Microsoft announced a new mobile operating system, Windows Phone
