Introduction and Specifications, Pricing and Availability

Sony Xperia Z Smartphone Review 01

The first Sony smartphone I reviewed was the Xperia TX, which wasn't the fastest device on the block. It featured a dual-core processor, 1GB of RAM and a great 13-megapixel camera. The display left me wanting more, and that is the job of the Xperia Z.

Sony have been struggling in the smart device market, but the Xperia Z is a departure from everything we know about their devices, and a head-first dive into a spec-filled, beautifully-designed future for the company.

Sony's Xperia Z has a Full HD (1920x1080) display, and it looks gorgeous - which will have people turning their heads on the street. Sony need this right now, just as HTC do with their troubles in the market after being a leader just years ago.

Let's get into the specifications, pricing and availability of the Xperia Z.

Specifications, Pricing and Availability

Sony have jam-packed the Xperia Z with some of the best components on the market - it truly stands on its own two feet, ready to swing at any potential competitor. We have a 1.5GHz quad-core processor from Qualcomm (the MDM9215M), backed up by the Adreno 320 GPU. There's 2GB of RAM inside the Xperia Z, and 16GB of internal flash storage backed up by a microSD card for expandable storage.

We have the 5-inch (441 PPI) display with a beautiful 1920x1080 pixels on top, and is backed by a shatter-proof and scratch-resistant glass. On top of this we have Sony Mobile BRAVIA Engine 2 helping the screen provide that extra 'pop'.

We have LTE support, Wi-Fi with the usual 802.11 a/b/g/n, DLNA, Bluetooth 4.0 and NFC support. Going from these specs, there doesn't seem to be much that the Xperia Z doesn't do - which is great. If you're someone who wants one of the fastest smartphones on the market, you will definitely want to consider the Xperia Z.

Newegg are currently selling the Xperia Z unlocked for $649.99 with free shipping at the time of writing. This is a decent price for the specs inside of the phone, and that gorgeous 1080p display. As always, Google's Nexus 4 (which is made by LG) is nearly half the price of the Xperia Z, and that is something to consider when thinking about picking up the Xperia Z from Sony.

Look and Feel

Sony's Xperia Z is one of the best looking smartphones on the market, as soon as you see it in person, you'll love the look of it from top to bottom. It feels great in the hand, and is great to use. The Xperia Z weighs in at just 146 grams, making it quite light in the hand.

In terms of size, we have (measured in inches) 5.47 x 2.80 x 0.31.

The front of the Xperia Z has the iconic SONY logo up the top, with the earpiece above it. Down the bottom of the Xperia Z we have the microphone, for you know, speaking into.

The Xperia Z from the back looks gorgeous, with its beautiful style and XPERIA logo on the back. We can see the power button sticking out from the side, which is definitely a departure from the usual styling we can expect from the likes of Samsung and LG.

Sony Xperia Z Smartphone Review 05

On the right side of the phone we have the loudspeaker, volume rocker, power button and SIM card slot (from left to right, respectively).

Sony Xperia Z Smartphone Review 03

On the left side, we have the power/charging microUSB slot and microSD card slot. These are little slits that can be opened up, exposing the port. When closed, the Xperia Z is actually water-proof - yes, water-proof.

Sony Xperia Z Smartphone Review 02

On the very top of the phone we have the usual 3.5mm headphone/speaker jack.

Sony Xperia Z Smartphone Review 04

At the bottom of the phone we have a little space to put a cord in and use it to hold it around your wrist.

Display and Speaker Quality

The display on the Xperia Z is definitely something to write home about, where we can enjoy a 5-inch 1080p display with a pixel density of around 441 PPI. 1080p displays on smartphones are really only coming onto the market now, but there are just a few right now, with the Xperia Z obviously being one of them.

Sony Xperia Z Smartphone Review 09

The 5-inch 1080p display on the Xperia Z is definitely a sight to behold. It is beautiful, but it does have its downsides, too. The viewing angles on the display were actually quite bad - and while this isn't a point that should make you decide to not buy the phone - we're telling you anyway. There would be times I'd use the Xperia Z laying down in bed, and if I didn't hold it right, the screen looked quite bad with the viewing angle.

Again, not something that makes it a showstopper, but it definitely a point that needs to be addressed by Sony. If they want to provide their devices with a high-end 1080p-capable display, at least make it close to perfect. I'd like to see their next 1080p-capable phone with better viewing angles.

The loud speaker on the Xperia Z was decent, capable of blasting out a surprising amount of audio when watching videos off YouTube, or replaying some movies I recorded on the excellent rear-facing camera. Spotify streaming was also great, again, loud enough for a few people to be sitting around.

Call quality was top notch on the Xperia Z. I had absolutely no complaints about it whatsoever.


Sony have sprinkled the usual features over the Xperia Z, where it again features their beautiful Timescape UI, something I loved from the Xperia TX, which we reviewed a couple of weeks ago now.

Sony Xperia Z Smartphone Review 12

I've gone over the Timescape UI in my Xperia TX review, so I'll just quickly skim over some of the things I enjoyed on the Xperia Z. The multi-tasking pop-up is great, and actually quite useful. We have some options down the bottom for the calculator, timer, some notes and a voice recorder. You can edit these shortcuts, too, which is nice.

To the right of the multi-tasking screen, we have your last-used apps. From here, it's like any multi-tasking UI overlay, you can visit the apps you were just using and either tap into them or swipe-to-close.

Another nice feature is the near-exclusive of the Xperia Z being water-proof. These days, most smartphones aren't water-proof, but the design of the Xperia Z itself has been built from the ground up to be water-proof. Each flap to access the ports on the phone is designed to keep water out, which is impressive.

The above shots show off some of the water-proof elements of the phone with their ports opened fully.

Performance and Camera Tests

The performance on the Xperia Z is next to unparalleled. The only device that even comes close is the pure Android experience on the Google (but LG-made) Nexus 4. The Xperia Z is stellar, both in real-world use and in benchmarks.

I used it as my primary phone for a little under two weeks, so I could get a great feel for the phone. This is why we don't do smartphone reviews every three days, because else it is too formulaic - there needs to be a 'real-world' feel, and then a 'real-world' opinion - which is why I don't like the word 'review' for smartphones.

Let's move onto some images from the camera. Here are some examples of the quality of the camera:

And now for some video samples:

Now let's get into some of those benchmark graphs!


Between our last smart device review and now, we've had Futuremark release 3DMark for Android and Rightware also with Basemark X. First up, we'll dive into some Basemark X results.

Sony Xperia Z Smartphone Review 22

As you can see, the Xperia Z kicks some serious ass - where it only loses out to the iPhone 5 and Nexus 4 in the 1080p results. It beats the iPhone 5 at 720p and equals the Nexus 4 in the same resolution test.

Sony Xperia Z Smartphone Review 23

3DMark for Android results are a little more interesting, where the Nexus 4 beats it in both presets - Ice Storm and Ice Storm Extreme. The Xperia Z scores 9063 points in the usual Ice Storm preset, and 5960 at Ice Storm Extreme. The Nexus 4 beats the Xperia Z by around 25% in the Ice Storm preset, and a little under 10% in the Ice Storm Extreme preset.

Moving onto GLBenchmark 2.5.1, and the 2.1 Egypt Classic Offscreen running in 1080p.

Sony Xperia Z Smartphone Review 24

The Xperia Z equals the Nexus 4 with 78 FPS, and thrashes everything else on our test bed by a large margin.

Next up we have the Fill Rate Offscreen, again at 1080p.

Sony Xperia Z Smartphone Review 25

Moving onto the GLBenchmark Fill Rate Offscreen (1080p) benchmark, the Xperia Z is a little over 10% slower than the Nexus 4. Again, it simply thrashes everything else we have tested.

Second to last, we have Quadrant 2.1.1 Pro with the Full Benchmark Total Score.

Sony Xperia Z Smartphone Review 26

This is something very surprising, where in Quadrant 2.1.1 Pro's total benchmark score, the Xperia Z simply flies ahead of everything - even the Nexus 4. Pushing 8168 compared to the closest competitor, the N4 with 4702. Nothing else even comes close to the Xperia Z.

And finally, some battery tests using GLBenchmark's built-in battery test, running 2.5 Egypt HD 60fps.

Sony Xperia Z Smartphone Review 27

Battery life on the Xperia Z wasn't too bad, but it doesn't set any sort of record. The phone has a slim profile, which means we can't just cram in a huge battery. 2.5 hours under extremely hard benchmarking like GLBenchmark 2.5 Egypt HD 60 FPS is always hard - but it beats the Nexus 4, which only has results of 2.2 hours under this test.

Final Thoughts

Something I didn't expect with the Xperia Z was to fall in love with it - upon opening it out of the box, I was in love. It looks gorgeous, performs admirably, and does it all without breaking a sweat. Have Sony gone from underdog to a true competitor? Yes, definitely.

It doesn't have the same plastic feel of the Samsung Galaxy devices, which I've come to dislike over time. Samsung have slowly been sliding in build quality (again, in my opinion) over the years, since the release of the Galaxy S II. The plastic feel of the Galaxy S III, Note II and more is getting a bit too much.

Sony have come out with a great device in the Xperia Z, something that is definitely worthy of your money. I would find it hard to believe that anyone could buy the Xperia Z and be disappointed in it, but I think Sony have a little while yet before they have the name that Samsung have in the competitive smart device market.

If they were to sell the Xperia Z for $399 outright and unlocked, and push it heavily in terms of marketing, it could soar. The problem is, Samsung have already got their foot firmly placed into the market, and whoever doesn't buy an iPhone, buys a Galaxy device.

Sony need to change this, and while the Xperia Z is worthy of this, they don't have the same power in the market that Samsung do.

Long story short, should you buy the Xperia Z? Yes, definitely. It's a great phone, and while it's more expensive than the Nexus 4, the Xperia Z has the Full HD display and being waterproof definitely isn't a bad thing. Besides the issues we experienced with viewing angles, there's not much bad to report.
