Nokia Lumia 710 Vs Sony Xperia U[Comparison]

We see how two budget rivals compare with Nokia's Windows Phone-powered Lumia 710 facing off against the Android-based Sony Xperia U.

Form
Sony Xperia U - 112x54x12mm, 110g
Nokia Lumia 710  - 119x62.4x12.5mm, 125.5g
Both Nokia and Sony consistently bring interesting handset designs to the table and that’s a trend which continues with these two models.
The Xperia U follows the signature style set for the rest of Sony’s latest Xperia range having a much chunkier form factor than earlier Xperia models under the Sony Ericsson brand.
Thin, curved and wedge-shaped edges have been replaced with broad flat surfaces that ensure better grip and a more solid feel to the device. Build quality and materials are also markedly better, adding further to the appeal of the devices.
The back panel is slightly curved, both across the width and length of the phone, which breaks up the overall blocky body shape quite nicely. Like the other Xperia models, the Xperia U features a transparent bar at the bottom of the handset, embedded with icons for the capacitive controls which sit just above.
However, the Xperia U has a couple of unique twists on this theme which it doesn’t share with the Xperia P and Xperia S models.
For a start the transparent bar houses LED lights which will switch colour depending on the phone’s theme and illuminate for incoming calls or playing music tracks.
The other slightly oddball feature is that the end cap below the transparent bar is removable and can be changed with a number of different coloured variants.
The one criticism we would level at it is the screen-to-bodywork ratio is way out, which means its 3.5-inch display looks a little lost in a sea of plastic.
Where Sony’s offering is highly angular the Lumia 710 has a softer and curvier aesthetic with a tapered top and bottom and a gently sloping back panel.
As might be expected, build quality might not be on the same level as the polycarbonate unibodied Lumia 800 but it’s still very good for a budget model and won’t leave you worrying about the structural integrity of the handset.
Both devices have a very clean look to them which we appreciate even though they’re from different schools of design, one curvy and the other slab-like.
Generally speaking, we prefer the Lumia 710’s overall appearance.
Winner – Nokia Lumia 710

Display
Sony’s Xperia U has a fairly small 3.5-inch capacitive LED backlit LCD display with scratch-resistant glass and four finger multi-touch.
It sports an 854x480 pixel resolution giving an impressive pixel density of 280 pixels-per-inch (ppi) which, combined with Sony’s Bravia Mobile engine creates some very sharp and bright picture quality, which is pretty much unprecedented on a £200 device such as this.
The Lumia 710 uses a slightly larger 3.7-inch capacitive LCD with an 800x480 pixel resolution, which is not too far behind the Xperia U for pixel density at 252ppi.
It’s fitted with Corning Gorilla Glass for extra durability and comes with Nokia’s ClearBlack coating to provide better contrast and visibility in bright light conditions.
Nokia’s display is very good, but colour reproduction is a little squiffy. The Xperia U’s touchscreen really is excellent for a budget phone.
Winner – Sony Xperia U

Storage
The Sony Xperia U has 4GB of on board storage against the Lumia 710’s 8GB, while both handsets feature 512MB of RAM and neither has a card slot for memory expansion.
It’s not the best scenario in either case but the Lumia 710 comes out looking a bit better thanks to twice the on board capacity.
Winner – Nokia Lumia 710

Processor
Sony has opted for a dual core ARM Cortex-A9 setup clocked at 1GHz on the ST Ericsson NovaThor U8500 chip with a Mali-400MP graphics processing unit (GPU). This makes the Xperia U quite snappy, in part thanks to Sony’s knack for optimising things.
Apps function very well and load quickly, multi-tasking works without a hiccup and there’s no noticeable slowdown in general operation.
The Lumia 710, being a typical Windows Phone, uses a Qualcomm Snapdragon Scorpion single core processor clocked at 1GHz, specifically the MSM8255 chipset with an Adreno 205 GPU.
As usual, this is well optimised to Microsoft’s software and delivers smooth performance on a par with the Xperia U.
Despite the differences in hardware, the performance delivered by each is equally impressive. This one’s a draw.
Winner – Draw

Operating System
Sony has promised the Xperia U will be upgraded to version 4.0 of Ice Cream Sandwich at some point this year, but in the meantime it’s still not a bad experience on Gingerbread.
The Timescape interface overlay, while perhaps a little hectic, is nonetheless very well implemented and doesn’t affect system performance at all.
Windows Phone on the Lumia 710 runs just as well as it does on other Lumia models, it’s a well optimised and speedy platform and is extremely stable to boot. One of the most notable features is the People Hub, which aggregates your contacts, social networking ,email, SMS text, instant messaging and a wealth of other communication mediums into one versatile space.
You can keep tabs on what your social circle is doing at a glance and get in contact with multiple people across multiple channels simultaneously. You also have control of who’s information is prioritised by the use of contact groups.
Our main gripe with Windows Phone is the lack of true Android-style multi-tasking. It has a form of multi-tasking but it’s based around hibernation and doesn’t keep you as up-to-date via push notifications as Android does.
Windows Phone also doesn’t have as many apps in the Windows Phone Marketplace as Android’s Google Play, but generally for what is there the bar is much higher when it comes to quality.
If social networking and keeping in touch in a fast, easy way is central to your phone experience you’d be hard pressed to do better than Windows Phone, making the Lumia 710 a clear choice.
However, Android does have its strengths, it’s versatile and more customisable than Windows Phone with a much wider choice of applications.
Winner – Draw

Final Thoughts
Both of these devices represent extremely good value for money at their budget-end prices of around the £200 mark. If you’re looking for a competent but cheap Windows Phone the Lumia 710 is a good option and likewise if Android is more your thing you get a lot of bang for your buck with the Xperia U compared to other similarly priced models on the market.
