Sony Xperia J review

 Review: November 2012  

Rating: 4 stars

In a nutshell: The Sony Xperia J is a good mid-range Android phone with stylish looks and an outstandingly good battery.

Today's best buy: Sony Xperia J SIM-Free Smart ... from Amazon (£0)



The Xperia J is a mid-range Android phone from Sony. In just 6 months, Sony has released a total of 8 Android phones, all called Xperia, so how does the peculiarly named "J" fit into the range and what is its unique selling point?


The answer seems to be "curves". For like the Sony Ericsson Xperia Arc S, the Xperia J is a slim, curvy model that fits snugly in the palm and has a unique look in the samey world of Android.

4 inch screen

Apart from the curves, the Xperia J doesn't really surprise us. It's a mid-range phone, so a 4 inch screen feels about right. It's a bigger screen than the compact Xperia U, but smaller than the flagship Xperia T. With a resolution of 480 x 854 pixels, we're thinking "mid-range".

Ice Cream Sandwich

Sony never seem to be able to get the latest release of Android into their phones. Ice Cream Sandwich (4.0) isn't so old, but it would be nice to have the latest Jelly Bean. The reason for the delay is probably the Timescape customisation that Sony have added, which gives good integration with social media.

5 megapixel camera

Sony have a reputation for producing amazing camera phones, but the Xperia J isn't one of those phones. Don't misunderstand us - with a 5 megapixel camera with autofocus and LED flash, this is perfectly respectable. But the VGA video resolution feels like last year's product, and the front-facing VGA camera doesn't improve our mood, despite it being video-chat ready.

Walkman music

We like the Walkman music player in Sony phones, even if just for sentimental reasons. With xLOUD, Clear Stereo and a manual equaliser, music quality here is as good as many top-end phones if you use a decent set of headphones. A stereo FM radio is welcome too.


Under the bonnet, the hardware powering the Xperia J is decidedly modest. A 1GHz Qualcomm processor with 512MB of RAM is adequate, but there are plenty of dual-core handsets in the mid range now, such as the Samsung Galaxy Ace 2 or the Sony Xperia U.

4GB of internal memory is enough to get started, but you may want to add a microSD card. Fortunately, the Xperia J will accept cards up to 32GB.


As you'd expect for a mid-range offering, this is a 3G phone with HSPA supporting maximum speeds of 7.2Mbps. There's also Wi-Fi support, Bluetooth and USB. A 3.5mm audio jack lets you plug in your own headphones. Usefully, the phone can also act as a Wi-Fi hotspot, enabling other devices to connect to the internet via the phone's 3G connection.

Battery life

If there's one area where the Xperia J excels, it's battery life. The battery has a very large capacity of 1750mAh. When you combine this with the relatively modest power requirements, you have a device that keep going for significantly longer than many rival smartphones.

Conclusion - curvy, good battery life

If our review has come across in any way negative, we want to correct that impression now. There's nothing wrong at all with the Xperia J. It just feels rather mid-range. The processor, in particular, is only just fast enough to power a device of this type. But nevertheless it ticks all of the required boxes. In addition it has good looks and exceptional battery life (for a smartphone).

Looks good but there are issues around memory. Internal memory (4Gb) is split into phone memory(1Gb) and internal memory (2Gb)....no idea where the other gig has disappeared too. Some apps can only be stored in the phone memory so easily fills up with apps you dont want and you cant delete them (even if you want too) then the phone slows down and tells you that you dont have enough storage, which is the cas, even if you have an sd card. I really love this phone but sony have really messed it potential up......bad SONY.

Absolute rubbish. This is the last time I buy any Sony product, if this rubbish phone has the Sony name on it, they should be ashamed. Wonder why Sony was a yesterday brand.
Goodbye Sony.Absolute waste of raw materials making this junk.

A terrible phone. The camera is awfull, it is sluggish and it feels chunky in your hand. Its only saving grace is a decent battery. Had the phone for 2 days and now taking it back and going back to my old xperia ray which is miles better in comparison. Avoid this phone at all costs.

I've had this phone for a few weeks now.
My main reason for selling my HTC One X was its abysmal battery life. In this respect the Xperia J is outstanding. At the end of a day of moderate use with the One X I'd be lucky to have 15-20% of battery remaining. With similar use the figure is 65-70% with the Xperia J
For a supposed 'mid-range' Android device, I have to say I am very happy with what I have got for my money.
Just one (very minor) gripe is that you cannot transfer apps from the phones internal storage to the SD card.
This apart, I cannot fault the Xperia J - fantastic value for money compared to the over-hyped over-priced One X.
