The Sony Xperia T has been out for while, and now the similarly priced Xperia V has been added to the line-up. When you first look at them you wouldn't be faulted for thinking they're about the same phone. Closer examination reveals that there are some significant differences, however, so Hardware.Info put both phones side-by-side to find out how they compare.
Sony seems to be going through the entire alphabet for naming its phones, and the letter assigned to a particular phone largely represents the market positioning. By that we mean that the Xperia J is an entry-level model, while the Xperia T and V are more high-end devices. It's not true for every single Xperia, however. The Xperia U, for example, certainly is not more advanced than the Xperia T.
The Xperia T and Xperia V are high-end models currently run on Android 4.0.4, but will receive an update to version 4.1. That they're high-end is reflected by their pricing, the T costs an average of £379 and the V costs about £383.
You could wonder why Sony is launching two similarly-priced phones that also perform almost the same. The significant difference is that the Xperia V supports 4G, courtesy of the Qualcomm Snapdragon S4Plus MSM8960. The Qualcomm Snapdragon S4Plus MSM8260A in the Xperia T does not have this feature.
The two phones are less similar than what you'd think when you first look at them side-by-side.
