The HTC One S is a stripped down, slightly more affordable version of the One X, featuring a lower resolution screen and a dual-core as opposed to quad-core processor.
The One S looks incredibly similar to the One X, featuring a one-piece anodised aluminium case and Gorilla Glass screen.
The One S is slightly smaller than the One X, measuring in at just 131x65x8mm and weighing 120g. The One X by comparison measures 134x70x8.9mm and weighs 130g.
This means that the device sits very comfortably in the hand, so shouldn't be a surprise for those used to smaller handsets such as the Apple iPhone 4S.
The use of metal is a nice touch, meaning that as well as feeling incredibly sturdy, the One S retains the high-end feel of the One X.
It's only when you turn on the device's 4.3in Super Amoled capacitive touchscreen that you can really tell it is a slightly more budget device, with its 960x540 resolution being slightly dimmer and less crisp than the One X's 1280x720 pixels 4.7in screen.
This isn't to say that the One S's screen and display is poor. As noted in V3's review, the One X's packs one of the finest screens we've seen on any smartphone and even though the S's display isn't as impressive, it's still on a par with other handsets in its £400 sim-free price bracket.
