The Sony Xperia U is pretty much identical to the Xperia S, sharing the same design but in a smaller chassis. The 3.5-inch screen has a 854×480 resolution, and spec wise you’re looking at a NovaThor U8500 dual-core 1Ghz processor with Mali-400MP GPU, 512MB of RAM, 4GB of storage, and five megapixel camera with 720p. Before you get too excited at the mention of a Mali GPU, remember that this is a slower version of what’s found in the Galaxy S II and other phones, so don’t expect anywhere near the performance.


Just like the P and the S, the Xperia U ships with Gingerbread instead of Android’s latest and great, Ice Cream Sandwich. Sony has promised an update for the handset in the future, but it’s still disheartening to see ICS missing. If you’re familiar with the software modifications that Sony has made to previous Android handsets, then you pretty much know the score with the U as well.

There is a little bit of bloatware bundled with the device – McAfee, OfficeSuite, WisePilot – and a few other included apps like WhatsApp and Astro File Manager. All of them can be uninstalled without any issues, allowing you to claw back some of that precious 4GB. Otherwise, expect to see Sony’s own apps, including Music Unlimited, Video Unlimited, Track ID, Media Remote, and Play Now, which is Sony’s app store.

Performance and Benchmarks

Sony has managed to achieve quite a feat with the Xperia U, slotting a NovaThor U8500 dual-core 1Ghz processor and a slower Mali-400MP GPU into the device. General performance is good too: flicking around homescreens and through apps is smooth, with very few instances of stutter or lag. Web browsing is good too, with pinch-to-zoom and double tapping resulting in smooth transitions.

Benchmarks seem to back that up too. It doesn’t blow the doors off by any means, but it does seem to be beating everything in this price category. Quadrant gave us a result of 2204, SunSpider 0.9.1 achieved 2526ms, AnTuTu returned 5359, and NeNaMark 2 scored 29.2fps.


The five megapixel on the Xperia U is decidedly middle of the road. It can take some nice photos in the right circumstances, with good colors and detail, but noise reduction seems to be ever present in photos.

The 720p video recording, however, is horrendous. The H.264 Baseline L3.1 clips have an average bitrate of around 6Mbit/s, but you wouldn’t know it.


The 1,290mAh battery sounds small, but it’s definitely a champ when it comes of performance. A video battery rundown test took a 720p H.264 High Profile L3.1 with AAC video and played it on loop with screen brightness set to 100%, and headphone volume set to 50%. After 4 hours and 37 minutes, the phone automatically shut down.
