The Sony Xperia U begs to be noticed with its removable bottom caps in different colors and boxy design, clearly aiming for the younger crowd, but its capable hardware and affordable price actually make it suitable for everybody.

Sony had customised the Xperia U's original Android 2.3 operating system significantly, and it has done the same with the Android 4.0 build. This means that, cosmetically, there's not a huge amount of difference after the update.

The Android 4.0 speed boost is also borne out in the Sunspider JavaScript benchmark. When running Android 2.3, the Xperia U completed the test in 2,719ms, but with the Ice Cream Sandwich update this dropped to 1,891ms - a 30% improvement, which bodes well for significantly snappier web browsing.

When running our battery life benchmark, which simulates continuous video playback, the updated Xperia U lasted just 5h 42m - an hour and 20 minutes less than the same phone running Android 2.3.

After using larger phones, such as the 4.8-inch Samsung Galaxy S3, the Xperia U's 3.5-inch screen feels tiny. We soon got used to it, though, and began to appreciate the reasonably high 854x480-pixel resolution. This gives a 280 pixels-per-inch pixel density, which puts it up in the top tier of smartphones for display clarity.
