Sony Xperia Z2 review: Feature-laden and waterproof

Summary: Every inch the premium high-end smartphone, the Xperia Z2 delivers excellent performance, screen quality and camera resolution without compromising battery life. However, the abundance of third-party apps may confuse some users, and we noticed that the handset sometimes runs hot.

The Xperia Z2 is Sony's current flagship smartphone. Unlike other players in this market, Sony releases two high-end handsets a year — so whereas the recently reviewed HTC One (M8) updates a year-old phone, the Xperia Z2 looks back just six months to the Xperia Z1. As a result, the £599 (inc. VAT, £499.17 ex. VAT) Xperia Z2 feels more like a series of incremental changes than a big step forward.

There is no mistaking the Xperia Z2's distinctive Sony look-and-feel, which includes a blocky chassis design with almost squared-off corners and a glass back. The same goes for the all-round silver side panels that accommodate the buttons and connectors.

Sony's trademark circular on/off button sits slightly north-of-centre on the right edge; beneath it is a small volume rocker and, at the bottom, a tiny camera button. Both buttons protrude enough to be easily found by touch alone.

Your MicroSD card sits under a covered bay on the right edge of the chassis. The headset slot is on the top edge, while the left side houses a covered bay that protects the SIM and MicroUSB charge connector. The smoothness of the edges is disrupted somewhat by Sony's magnetic dock connector, which is recessed into the left edge.

The SIM and MicroSD card slots are on the handset's edges because the back is not removable. They need to be covered so that the Sony Xperia Z2 can meet its IP58 dust and water resistance ratings.

IP58 means that the handset is 'dust protected' and can handle immersion in 1.5m of fresh water for up to 30 minutes. As it has done with past Xperia handsets, Sony is promoting the fact that you can take underwater photos. Perhaps more important for the butter-fingered among us is that, if the covers are all closed, you should be able to drop this phone in the bath without any ill effects.

The glass front and back are characteristic of the Xperia range, and as with previous handsets the back is smooth, shiny and reflective. A small ridge runs all around both front and back edges where the side panel protrudes ever so slightly. It's no problem on the front, but on the back it's noticeable, and slightly irritating, every time you pick up the handset.

The screen measures 5.2 inches from corner to corner, its 1,920-by-1,080-pixel resolution delivering an excellent 424 pixels per inch. Sony throws a lot of technology at the IPS LCD panel: X-Reality, which we've seen before, is designed to smooth out edges and deliver crisp pictures. Triluminos, also not new, deepens the colour palette — in effect making images look more 'zingy'; and the new Live Colour LED is designed to improve colour depth and gradation. Sony supplies a utility that lets you alter the white balance, taking it right down to black and white if that's what you want. The net result is a high-quality screen that works particularly well for movies.

There's a lot of bezel at the top and bottom of the screen, which is characteristic of Sony handsets. You'd hardly notice that there are two speaker grilles built into the very top and bottom of the phone. Given Sony's experience in multimedia, and its keenness to sell its 'ecosystem' to us on this handset (of which more later), sound output through these speakers is disappointing, lacking bass and punch. Audio quality is certainly nowhere near as good as on HTC's new flagship One (M8), which trounces other smartphones in this respect.

However, Sony has included noise cancellation, which you can experience if you use compatible earphones —like the ones provided with the Xperia Z2. Audio output is remarkably rich under these conditions — it's just a pity that the earbuds are the flat type that many ears do not like.


Sony has equipped the Xperia Z2 with a 2.3GHz Qualcomm Snapdragon 801 SoC. This is the current top-of-the-range for handsets, although Samsung's Galaxy S5 has a slightly faster 2.5GHz version of the same chipset. Supported by 3GB of RAM, the result is a smartphone that more than holds its own with its high-end competition.

As you'd expect with a flagship handset, the general specifications are out of the top drawer. The Xperia Z2 is a quad-band GSM/GPRS/EDGE handset with UMTS/HSPA+ and LTE mobile broadband. The wi-fi (802.11a/b/g/n/ac) includes Wi-Fi Direct, DLNA and wi-fi hotspot support. MHL (Mobile High-definition Link) is supported through the MicroUSB port. There is also NFC, GPS, Bluetooth 4.0 and Sony's own Smart Connect. The latter can launch specific apps when you connect a peripheral — plug in the headset, for example, and you can have the Walkman app start and resume playing a track from where it left off.

The main (rear) camera has a resolution of 20.7 megapixels, and there's a multitude of different settings, filters and tweaks. Sony's Superior Auto mode, which makes settings automatically, caps the resolution at 8 megapixels. You can shoot 4K video too. The front camera's resolution is much lower — just 2.2 megapixels.

There is 16GB of internal storage, of which 10.7GB is available out of the box. Android 4.4 and Sony's skin occupy some of this space, and more is taken up with an array of preloaded applications and settings. Many of these are part of the Sony ecosystem, with the Walkman app sitting alongside Android's own Music app, and the likes of Video Unlimited, PlayStation, PlayStation Mobile, Xperia Lounge and Sony Select peppering the app drawer. Sadly their icons lack design continuity. A new application, What's New, brings together various Sony media in one place. Added to this is a range of third-party add-on apps. It all feels very cluttered.

As if in recognition of this, Sony has included a simplified home screen — something which seems to be becoming quite popular as a way of helping people cope with the apparent complexity of handsets.

The 3,200mAh battery kept us going for a day's mainstream usage without the need for a recharge. If you're a power user, you may like Sony's Stamina power management mode, which allows you to fine-tune which apps are permitted to consume power and which are not. An alternative Low-battery mode disables a range of user-defined features when the battery falls below a set percentage.

When using the advanced camera effects, we found that the handset started to run warm, with significant heat coming through the backplate. In fact, before we had finished working with it, the handset automatically shut the camera down, telling us this was because of hot running.

Having spent time with both the HTC One (M8) and Samsung Galaxy S5, which share the same chipset, we can confirm neither of those handsets run warm. We hope Sony finds a fix before long.


The Xperia X2 is every inch a premium high-end smartphone. Performance is excellent, it has a high-quality 5.2-inch IPS screen and the 20.7-megapixel camera has some appealing features — all without compromising battery life.

However, Sony appears to want to throw everything, including the kitchen sink, at the Xperia X2. The abundance of third-party apps may confuse some users, particularly where they duplicate features that are already part of the Android OS. We're also concerned about a potential problem with overheating. And for a company that majors on movies and sound, we found the speakers underwhelming.
