Windows 10 for Phones and Small tablets User agent spotted

While we wait for the release of the preview of Windows 10 for Phones and Small tablets under 8 inches, small details keep leaking out of Redmond’s castle. A keen-eyed reddit user spotted the OS on whatsmyuseragent.com running on a Lumia 635 (id-313). The OS identifies itself as Windows Phone 10 and reveals the updated user agent string. It now spoofs Android 4.2.1 as opposed to Android 4.0 in Windows Phone 8.1 and the Trident Engine has been dropped, replaced by the new Edge engine introduced in Windows 10 proper.

As per our earlier reporting on Edge, this showcases massive improvements over the current Trident engine:

With the Windows 10 Technical Preview Build 9926, Microsoft has included the new web rendering engine that Spartan will use. AnandTech used this rendering engine to run web performance tests. As per their numbers, the performance increase of the new Javascript engine is massive, and it brings up to par with Google Chrome. As expected, the new engine performed well in Sunspider tests. In Google Octane 2.0 test, it comes in roughly the same as Chrome, for a massive 81.8% increase over the old rendering engine and Kraken continues this with a 45% jump in performance
