There is a latest research by a Canadian software company showed that Apple’s iOS is 50% slower at loading web pages than Google’s Android operating system (OS).
Through the comparison between Apple’s iOS version 4.3 and Google’s Android version 2.3 by web performance specialist Blaze Software measured 45,000 page loads, it showed that iOS loaded web pages over two seconds slower than Android. In addition, the iPhone 4 was slower than Google’s Nexus S Smartphone 84 percent of the time when accessing the Web through the browser that operates applications like Twitter and Facebook, Blaze was unable to compare the Apple Safari and Google Chrome browsers that users access directly from the phone’s home screen.
According to the Blaze’s CTO and co-founder, Guy Podjarny said: as the growing of user‘s demand they expect the full experience on tablets, not the simplified mobile sites. But as we know that tablets use the same OS and similar hardware phones do. In other word Android’s edge will make an even greater impact.
