Call quality is very good on the Xperia U - loud and clean voices in the earpiece, and on the other side they said we could be heard very well, with distinct sound and strong volume.

The 1320mAh battery is rated for 6 hours and 36 minutes of talk time, which is about average, and up to 6 hours of video playback. With moderate to heavy usage you should be able to last a full day, and even one more if you don’t grab the phone that often.


Sony has cut a few corners to achieve the very affordable price of the Xperia U, like the lack of oleophobic coating and microSD slot, but these are still overshadowed by the cool design and the contemporary specs like a dual-core processor and screen with good pixel density.

Where it really dropped the ball, however, is the camera module - we’ve seen better 5MP shooters in Sony handsets dating back to 2010, especially in the video capture department. Yet something had to give, otherwise we’d have the perfect phone for the price, considering the very good call quality, strong and clear loudspeaker, and the removable battery with decent endurance.

Still, you’d be hard pressed to find more phone for the price. You either have to go back to Sony’s single-cores of last year, like the Xperia ray with its slimmer design and better camera, or open your wallet wider, and pony up for an HTC One V, which has a better camera and Android ICS.

The Samsung Galaxy Ace 2 is also a good choice one price level up - it has uninspiring design, but is fast and takes very good pictures. If we venture outside the Android universe, we might consider the Nokia Lumia 710 a better offer in terms of camera capabilities, albeit with a single-core processor.
