This isn't a phone that particularly sells itself on its camera credentials, and as such, it just kind of gets on with the job.
Some of our sample shots were taken in a slightly overcast London. While light was in reasonable supply, the default settings (auto everything) left some of the images washed out, almost feeling like there is a thin, misty veil over the lens. When the sun did come out to play, though, this cleared up a treat, giving crisp and bright images. There are a selection of manual options for you to poke about with, which do give a modicum of control, and some novelty panorama / 3D modes for the occasional creative flirtation. Our guess, however, is that if you are eyeing this phone as something to potentially live with, the 5-megapixel shooter, set to default, will do just fine for those candid moments and occasional memories you need to preserve.
It might come as no surprise, then, that video mode fares just as sufficiently. You're not going to be filming any masterpieces, but it's adequate for YouTube fodder. Our sample video below caught lots of vibrant inner-city wildlife, but some pixelation can be seen when movement is sudden. All in all, it's a very average affair.
Before you groan about the out-of-the-box Android 2.3.7 install, give us a moment. Yes, it's not ICS, but that's not necessarily a crisis. Sony's skinning is pretty light, and at the top level, doesn't look all that different from the UI of Android 4.0, even if you have to squint a little bit (and choose the blue theme). In a weird interpretation of "out with the old, in with the new," Sony says that ICS will come to the Xperia U in Q2 – so very soon – but will still be hidden under its Timescape UI. That means it'll largely look and feel the same anyway, but with the more recent features.
As is the law, the first thing you must do with a new telephone is flick the app screens left and right. No? So many snap judgements are made during those first vital seconds as you mindlessly flick left and right. Performing that less-than-scientific test here is reasonably gratifying. We already noted in our hands-on, that navigation was neither zippy nor sluggish, and that about sums it up. The 1GHz dual-core ST-Ericsson U8500 processor does its best to leave your experience unhindered. That said, once you've had the phone for a while, and more and more applications compete for resources, this might start to change. For now, however, we're quite pleased with the speed and ease at which we got around the user interface.
Beyond that UI, Sony has filled the Android room with a few bits of its own furniture, notably its audio and video services. That's hardly surprising given its recent departure from long-term beau Ericsson. Now that it's got the place all to itself, it's evidently keen to leave its mark, and that means Music Unlimited and Video Unlimited take pride of place. You don't have to use these, of course, as there are other media playing options. But, if you're already a signed-up member of the Sony-Unlimited club, then you'll jive to the Xperia U's beat right from the off. One corner of the Sony universe that doesn't get explored, however, is its PlayStation franchise. There's nary a mention of the PS Store or PlayStation certification, which might not be surprising given that the bigger Xperia P also seems to have been left off the invite list.
If you're still in any doubt about it, the short version is that the software is more of the same that we've come to expect from the Xperia brand. There's the good (some Android 4-esque features like app folders), the bad (McAffee's persistent antivirus) and the ugly (connecting to a Mac to transfer files needs a cable and more software). The good news is that most of the stuff that you don't like can either be uninstalled or easily ignored, leaving you to mold the phone to your liking.
Performance and battery-life
When you have less display to light-up, you stand a good chance of being able to do it for longer. The 1,320mAh battery is a sliver over that of the Xperia P's 1,305mAh, and this, factored with the lessened screen demand, do help keep the juice flowing a little longer. On our standard battery-draining test (WiFi on, brightness at 50 percent, and a continuous video playing) the Xperia U's engine room kept it huffing and puffing for a smidgen over five hours, which is better than the P could manage, and about on a par with the larger (and more power-endowed) Xperia S. That five hours isn't all that far off of the "up to" six hours in the press materials, which obviously tend to err more on the optimistic side.
The Xperia U managed to give us nearly two days of service, before it'd start pulling at our trouser leg, asking us to feed it.
What about when you're not settling in for marathon movie sessions, which, let's face it, is likely most of the time? In our time with it, the Xperia U managed to give us nearly two days of service, before it'd start pulling at our trouser leg, asking us to feed it. This is with WiFi and data always on, regularly checking emails, browsing the web and, well, the typical tasks of a fairly demanding user. This means that if you're away from the security of a wall port for more than 36 hours, then you'll be fine, but you'll likely want to be charging it most nights just in case, as is unfortunately the norm.
Of course, it's not just lighting up that screen, and juggling all the radio signals that drain the battery, those dual-cores will be taking a slice of the power-pie too. Yes, this brings us onto the more measured performance, and those all-important benchmarks. As you can see, the little Xperia U equaled, or saw off its Xperia P label-mate across the board showing that there's plenty of fight in the fella. In fact, it also pushes HTC's nearest current phone into the sand on most tests.
