The Good HD-resolution screen. NFC implementation is great. HDMI port. Quick-launch camera software is very fast.

The Bad LCD screen could be better. Average battery life. Non-removable battery. Non-expandable memory.

The Bottom Line The Xperia S is packed to the gills with great ideas, unique features and solid hardware. It's an especially good smartphone for lovers of multimedia.

You'll notice the absence of Ericsson in the name of this latest smartphone from Sony, but is this more than a change of name? Has Sony jettisoned the dead weight of Ericsson for the future or are we in for more of the same?

Design

The Xperia S doesn't jump out at you the way a coloured phone might, or a phone with an obviously larger display. Sony has chosen quite a demure approach when crafting the Xperia S, and the result is a rather unassuming monoblock with some intriguing additions. Back is Sony's signature "human curvature" across the battery cover, though the curve here is far less severe than in previous releases. Sony covers this area of the phone with a soft-touch plastic and manages to give the S a premium quality feel that so many modern smartphones lack.

Below the display you'll find a transparent plastic strip with the iconic Android navigation icons embedded. This is an attractive touch, but it also houses the phone's antenna, according to Sony.

The 4.3-inch HD resolution screen is the centrepiece of this well-designed device. Sony opts for the same higher-resolution display we'll see throughout 2012 in smartphones (1280x720 pixels) and in this 4.3-inch array this equates to 342 pixels per inch — slightly higher than Apple's iPhone 4S . This display is perfect for everyday browsing, and fantastic for video playback, but it's not without its faults. Off-axis viewing is noticeably poorer than other screens at this price point, and there is an obvious colour banding issue when viewing still images, where colour gradients are displayed as distinct bands of incrementally different shades of colour, rather than a singular, smooth solid.

General phone navigation is performed using three capacitive touch buttons located between the screen and the clear antenna panel. Using these buttons takes a moment's more concentration than you might expect — we found these buttons responded to our input a half-second after we pressed them. For some, this will seem like a fault of sorts, but we wonder whether this is a deliberate design decision aimed at curbing the number of times these keys are pressed accidentally. Either way, it's not really an issue in our opinion.

We do like that Sony manages to include both a dedicated HDMI port and camera shutter release without interrupting the design of the handset. Other manufacturers refuse to include these options so as to maintain clean lines around their products, but Sony proves you can have your cake and eat it, too, in this regard.

Take off the battery cover on the back of the Xperia S and you'll quickly realise that you can't access the battery at all. Sony has encased the handset's power behind another plastic cover so there is no way to carry two batteries and switch one out throughout the day. There is no microSD card slot either, though Sony does include 32GB of internal storage, plus access to 50GB on cloud storage service Box.net.

Performance

Sony's decision to use a dual-core processor in the Xperia S makes sure that this phone keeps pace with other competitor releases, even if quad-core processors are the choice for other phone makers in their top-tier devices. We certainly don't feel this is a deal-breaking decision on Sony's part, as the need for quad-core chips is still very much in question and the performance delivered in the Xperia S seems adequate to us. We have encountered a few small pauses in performance across the user experience, but nothing that really holds this phone back. It doesn't feel like the latest and greatest, but it certainly runs smoothly.

Sony's choice of battery also fails to break new ground, with its 1750mAh battery being a pretty standard capacity for smartphone at this time, and a standard we hope to see superseded in the near future. The Xperia S managed four hours continuous video playback with the screen brightness set to 100 per cent. During a business day with auto-sync on, the battery lasted 14 hours, but this figure more than doubled with lighter use and no auto-sync over a weekend.

The custom Xperia Android overlay takes on a new name and a few cool new features in this release. Now known as NXT, the design of Sony's Android experience is much lower key than HTC's Sense UI, but packed with nice touches. For example, the clock on the home screen can be swiped to the left to reveal a music player shortcut, Sony's Track ID service (like Shazam) now works in the Music Unlimited app, and Sony has designed its own connectivity widget so users can quickly switch on and off features like Wi-Fi, GPS and mobile data. This is one of those phones that every couple of days we stumbled across something else new and undocumented, which is always fun.

We should also note that we've experienced some instability in the firmware that our review unit is running on, with a number of Force Closes occurring during our review period. However, our review unit is not Australian stock, so it is likely that the gremlins causing these minor glitches will be ironed out before its Aussie release.

Camera

One area where Sony is pushing the limits is with its 12-megapixel rear-facing camera. Using Sony's Exmor-R image tech, the camera fares well in low light, and takes some pretty great photos under optimal lighting conditions. We did note that the photos we've taken look quite noisy when we inspect them closely on a PC screen, but on the phone's display they look fantastic.
