359gsm (via My Nokia Blog) recently pitted the iOS 4.3-based iPhone 4 and the iOS 5-based iPhone 4S against a Windows Phone 7.5 Mango-based Nokia Lumia 800 smartphone in various benchmark tests. In every test, both the iPhone 4 and iPhone 4S significantly outperform one of the best Windows Phone options on the market. This is in contrast to reports in April, prior to Mango’s release, that claimed Window Phone’s IE 9 on Mango devices beat mobile Safari in similar browser benchmark tests.

You can view the results in the video above or get the full results below (via 359gsm). As you can see, the iPhone 4S significantly passes the Lumia 800 in all tests, including: Browsermark tests, Speed Reading test, Sunspider, Acid3, and HTML5. The iPhone 4 also outperforms the Lumia in most tests, although by a narrower margin.
