iPad 2 turned out to be more powerful in hardware than commercially available competitors, but we all know that the “bare” hardware performance is far from the most important thing. The software component is also extremely important. Apple is one of the few companies that pays maximum attention to software, although it is in an advantageous position, since it also produces hardware for it. On the other hand, Motorola also actively collaborated with Google when creating the Xoom tablet – it was quite possible to adapt the software. The latest research from Sencha shows that Android still has room for improvement, and Apple’s software is considered one of the best on the market for good reason.

Sencha distributes web development tools and has been testing accordingly. She checked the web browsers in iOS on the example of iPad and iPad 2 and in Google Android 2.2 and 3.0, which worked on the Samsung Galaxy Tab and Motorola Xoom, respectively. All browsers are based on webkit, and rather new versions, as Sencha experts note. In the case of iOS 4.3, it was Safari based on WebKit 533.17.9 plus the Apple Nitro Java script engine. Android 3.0 uses an even newer version of WebKit 534.13. By comparison, Safari 5.0.4 for Mac OS X uses WebKit 533.20.27. Despite the superiority of the Android browser in terms of the version of Webkit, in real tests it did not perform well, but first things first.

In the Acid3 test, both competing browsers scored an identical score of 100 out of 100, but neither rendered the test image very accurately either. In Safari you can see a corner of pink lines to the right of the numbers and the same line in the upper right corner.

The browser in Android 3.0 also messed up. The inscription “Acid 3” lost its shadow and turned redplus a set of red pixels was found in the upper right corner, which should not be there (I personally did not see them).

Next, a test was carried out using Modernizr. It allowed us to determine the quality of support for HTML5 capabilities by mobile web browsers. According to experts from Sencha, it is far from certain that all the declared functions in the browser will actually work. In the case of the iPad 2, it happened, but not everywhere. The test showed that the program has support SVG, CSS 2D transforms, CSS 3D transforms, CSS transitions, WebGL and WebSockets, but no Inline SVG. However, on demo sites using this HTML5 feature, everything worked correctly in Safari. On the other hand, the declared support for WebGL did not justify itself – the content based on it was not displayed. But the iPad did a great job with HTML5 video and audio. Overall, Sencha found the tablet version of Safari to be one of the most compatible with HTML5 standards.

In the case of the Android 3.0 web browser, things were not so rosy. Of course, it adds a lot of features that weren’t available in the bundled Android 2.2 browser, and Modernizr has found support for technologies such as SVG, Inline SVG and CSS3 3D, but, as written above, the fact that it exists does not mean that it will work. When trying to view web pages even with those HTML5 technologies that are supposedly supported by the browser, the researchers ran into problems. Content was displayed incorrectly, page elements were misplaced, font problems were found, etc. HTML audio played, but this process cannot be controlled. Moreover, when closing the page or even the browser, playback continued. HTML5 video failed to start at all. A Sencha representative stated that this browser it would be nice to learn how to work normally with HTML4, and then do something with a newer version of the standard.

When it comes to JavaScript performance testing using the SunSpider test, the iPad 2 was in the lead, although the Motorola Xoom did well, outperforming Apple’s latest tablet in some tests. The iPad also still has “gunpowder in the flasks”, but the Galaxy Tab was far behind the competition, its software platform is too outdated.

As a result, iPad 2 (and the first too) was recognized as an excellent platform, supporting most of the modern features of HTML5 and CSS3. The competitor in the face of Android still needs to develop and develop. Sencha continues to wait for the release of “an outstanding tablet based on Android”, because so far there is no such thing on the market, according to the company’s employees. [AppleInsider]
