"That's not to say it isn't interesting that Android's WebView for apps is faster than iOS's UIWebView for apps, but it just isn't true that these results are indicative of anything regarding Mobile Safari's performance. It's easy to see that Mobile Safari is faster than UIWebView - just run something like the SunSpider benchmark twice, once in Mobile Safari and once in any app from the App Store with a web content view. On my iPhone 4, Mobile Safari runs SunSpider almost three times as fast as an app using UIWebView."
We would now consider this study to be flawed at best, if not completely meaningless. We would, however, look forward to a similar test done under conditions that could lead to an accurate measurement.
Web analysis site Blaze has conducted an extensive study to compare the browser loading times of Android and iPhone, and we think most of our readers will be very pleased with the results. In a dominant showing, the Android browser was determined to be, on average, 52% faster than the iPhone's.
Blaze loaded over 45,000 web pages from 1000 web sites (real sites, mostly those of Fortune 1000 companies), using an iPhone 4 running iOS 4.3 and a Nexus S running Android 2.3 'Gingerbread.' Each page was loaded multiple times on different days. Their study used a custom benchmarking app that measured page load time. Stock browsers were used for each OS. While the average speed of the Android phone was 52% faster than the iPhone's, the Nexus S also handily beat Apple's flagship device 84% of the time in head-to-head browser loading races.
When broken down into a comparison of mobile sites vs. desktop versions, Android's primary advantage became apparent. Mobile versions of sites loaded in roughly the same time for each phone (two seconds on average) but for regular sites, the Nexus S loaded them faster by over a two second margin (2.1 seconds to be exact, compared to 4.3 for the iPhone).
While these results likely comes as little surprise to many Android users, many Apple fans and other less Android-centric smartphone customers may be surprised to hear that Apple's software and hardware do not, in fact, "just work" better in this case. We can only wonder how Steve Jobs will find a way to frame this one as an advantage for Apple when it comes time for his next grand unveiling.
