Despite Microsoft’s claims earlier this year that its Windows Phone 7.5 Mango devices running IE 9 would beat out mobile Safari in browser benchmark tests, the latest video comparison uploaded by 359gsm shows quite the opposite. Placed side by side, the iPhone 4S and the iPhone 4 both beat out the Nokia Lumia 800.
The iPhone 4S can be seen significantly surpassing the Lumia 800 in performance in all tests, which include Browsermark tests, Speed Reading test, Sunspider, Acid3, and HTML5. The iPhone 4 also didn’t do too shabby, beating the Lumia 800 by a smaller margin in most of the browser tests.
The iPhone 4 is running iOS 4.3 while the iPhone 4S is running iOS 5. The tester notes that with the Speed Reading Test, iOS 5 on the iPhone 4 gives it a big boost up in speed. You can take a look at the video for yourself or catch the complete scores below. A higher number is better in most of the tests, except for the Sunspider Test where a lower number is better.
