Japanese smartphone brand Sony, which of late has released a flurry of smartphones, has now come out with the Xperia Z5 Dual flagship handset. This smartphone is positioned as a successor to Sony’s Xperia Z3 Plus. This got us interested in carrying out a review of the handset by subjecting the device to multiple customized performance tests.
Design and Display
As soon as we unwrapped the Sony Xperia Z5 Dual, the smartphone gave off a feeling of being similar to the Xperia Z3 Plus in terms of design. The Sony Xperia Z5 Dual, is thicker than the Xperia Z3 Plus, at 7.3 mm; the smartphone also weighs in at 154 grams.
The Xperia Z5 Dual also features a metal frame on the exterior. The handset also incorporates perfectly rounded edges, and matte finish. But when we held the phone in the hand the device seemed slippery even after we completely dried our hands.
Nonetheless, the main plus as far as the Sony Xperia Z5 Dual’s design is concerned is the location of the fingerprint scanner that is present on the right hand side of the smartphone exactly at the location of the thumb finger at almost the rear of the handset. We consider this aspect useful considering the fact that it now takes less time to unlock the Sony Xperia Z5 Dual, in comparison to other high-end/flagship smartphones.
Below the fingerprint scanner, there are the usual volume rocker keys; below the volume buttons, there is the camera shutter key; we found the location keys a tad inconvenient considering the fact that operating these buttons seemed a challenge when we held and operated the phone with one hand.
The rear of the Sony Xperia Z5 Dual gives off a glassy look and feel, thus making the smartphone’s exteriors extremely smooth and slippery. As far as the actual design is concerned, the Sony Xperia Z5 Dual features a comparatively smaller 5.2-inch display having resolution of 1080 x 1920 with pixel density of 424 ppi.
During our testing, in full sunlit outdoor conditions, we could use the customized brightness slider to set the brightness at optimum even for viewing the contents of the screen in full external conditions.
Apart from full bright conditions, we also used the brightness slider to lower the brightness so as to read comfortably at night in low-light conditions. WhatsApp notifications and even multimedia content could easily be read in ow-light conditions.
Rendered images are also sharp, so are stored images that are displayed on the screen. We could also prevent the display of the Sony Xperia Z5 Dual via the Smart Screen functionality. We consider this aspect really useful as far as both the business class of users as well as the general home users are concerned.
Finally, the Sony Xperia Z5 Dual’s display is protected by an external scratch-resistant glass with oleophobic coating. This screen supports both Multitouch and 16 Million colors.
Processor and Memory
Under-the-hood, the Sony Xperia Z5 Dual incorporates a 1.5 GHz quad-core Cortex-A53 and a 2 GHz quad-core Cortex-A57 CPUs within a Qualcomm Snapdragon 810 SoC and an Adreno 430 GPU; in tandem with a 3GB RAM.
When we used the handset, in a multitasking and multi app scenario, we could not experience any major glitches in performance and the instruction processing capabilities, save for minor lags which are purely dependent on the apps (and their credibility) that are launched at a particular point in time.
Even video streaming from Netflix proved to be a breeze. Stored multimedia files also played well relatively glitch free. Also, during our testing, high-end games such as Asphalt 8: Airborne and Dead Trigger 2 ran in a hassle-free manner.
As far as the actual memory is concerned, the Sony Xperia Z5 Dual offers 32 GB default internal storage that can be expanded up to 256 GB with an external microSD card.
We tested out the 23 MP rear camera, of the Sony Xperia Z5 Dual, and found the quality to be fairly good. This shooter let us capture 2160p videos at 30fps, 1080p at 60fps, 720p at 120fps along with allowing HDR video capture/recording.
During our testing, the auto-focus functionality offered by the 23 MP camera of the Sony Xperia Z5 Dual came across as a true genius. Low-light photography is also impressive, as pixellation and external noise are visible only when the images are observed in great detail; the general everyday users would not be able to identify these aspects.
The Sony Xperia Z5 Dual also provides a 5.1 MP front shooter that offers video recording of 1080p and HDR videos. We found that the secondary snapper captures good snaps but these are restricted to daylight conditions (where there is plenty of light).
The Sony Xperia Z5 Dual runs Google’s Android 5.1.1 (Lollipop) operating system out of the box. During our testing, the Xperia Z5 Dual responded effectively to the double-tap which activates the display or puts it to sleep. We could view all the menu contents, within Settings, in a tabbed view format reducing on-screen clutter.
The overall user interface (UI) is pretty much similar to the Xperia Z3 Plus. There is also bloatware that requires manual deactivation. This process was a pain to us during our testing.
The Sony Xperia Z5 Dual is powered by a 2,900 mAh battery that cannot be removed at any cost. A big advantage here is the Qualcomm Quick Charge 2.0 fast charge aspect which during our testing charged up the battery by as much as 30 percent in just half an hour of plugging-in to charge. Do remember that the battery was fully discharged, before we tested out the Quick Charge functionality.
Also, during our testing, we could view videos (stored within the handset’s external memory) continuously for more than 11 hours. High-end gaming naturally depleted the battery life substantially; upon restricting the usage to calls and basic internet, we obtained battery life that lasted for more than a day which is impressive.
The Sony Xperia Z5 Dual is an impressive smartphone when its performance is taken into consideration. However, its outer overly-smooth and slippery design is none to impressive.
