The Sony Xperia Z3 and the Motorola Nexus 6 form part of the Xperia Z and Nexus series and were officially announced in September and October of 2014 respectively.

They hit the market later exactly a month later after the announcement. It must be noted that unlike the two previous Nexus smartphones produced by LG, the Nexus 6 is manufactured by Motorola. The two devices are extremely feasible to those who are looking for medium budget smartphones with decent features or specifications. The two gadgets have provision for inserting only a single SIM and are available in quite a few catchy colors if that is something that you are looking for in a smartphone.

Dimensions, Weight, Body Material and Ruggedness

The Nexus 6 bears a very strong resemblance to the Moto X. After all, these two smartphones are both from the same manufacturer – Motorola. The Xperia Z3 comes with a size of 5.75 x 2.83 x 0.29 inches as against the 6.27 x 3.27 x 0.40 inches of the Nexus 6. With respect to weight, the Sony Xperia Z3 is 152g contrasting the 184g Motorola Nexus 6.

While the Sony smartphone comes with a glass body and metal accents, the Motorola gadget houses a plastic back. Talking about the ruggedness issue, the Z3 takes pride in having the IP 68 certification. This makes it both dust and water resistant. On the other hand, the Nexus 6 is known to be splash resistant.


The comparatively small size and less bulk of the Sony Xperia Z3 make it comfortable and less tiring to hold in your hand over a long period. Also, the glass with metal combination adds elegance to the smartphone. Being more rugged gives the device an extra boost.

Screen Display, Resolution and Pixel Density

Like many of its other smartphones, Sony offers its Xperia Z3 a 5.2-inch screen. The Nexus 6 has an increased screen size of 6 inches over its earlier models. Sony has made its handset with an IPS LCD, and Motorola has chosen to opt for an AMOLED display. Additionally, Sony Xperia Z3 vouches for a TRILUMINOUS display coupled with X-Reality that is intended for mobile picture engines. While the Z3 comes with 1080 x 1920 pixel resolution and 424ppi pixel density, the sixth Nexus handset offers a pixel resolution of 1440 x 2560 and a pixel density of 493ppi. Moreover, the Nexus 6 screen is made of Corning Gorilla Glass 3.

Verdict: The big size screen with far better pixel resolution and pixel density make the Nexus 6 screen win the battle with ease. Even as the enhanced pixel density and resolution result in images and texts of utmost clarity, the big size makes Internet browsing, gaming and online reading a true pleasure. The only flip to this is the drain on the battery. Apart from the screen display and resolution, the fact that the device encompasses a scratch-resistant glass for its display makes it a better option.


Snappers have never been a reason for a showdown in a Sony handset. Here too, the Sony smartphone comes with a 20.7MP primary snapper with LED flash at its rear. Although the same rear snapper in the Motorola device portrays dual LED flash, it is only a 13MP camera. Setting aside the common features, the Sony Xperia Z3 gives full support for optical image stabilization against the Nexus 6 paving the way for other aspects like Touch to focus, Digital image stabilization, and smile detection. The camcorder in the Nexus smartphone can record 720p HD videos in addition to 4K and 1080p HD videos rendered by both handsets. The secondary front camera is a 2.2MP snapper in the Z3 in comparison to the 2MP camera of the Nexus 6. Another distinct feature of the Xperia Z3 is the availability of a button solely for operating its snapper.

Verdict: If it was a cakewalk for the Nexus smartphone with its screen, then it is now the turn of the Sony Xperia Z3 to take over. Thanks to its optical image stabilization support, shots come out well irrespective of the lighting in the background. Selfie lovers will also find their photos a bit better looking with the Sony camera.


Whilst both Sony and Motorola have decided that a quad core processor is what would best suit their smartphones; they have made the processors’ clocking frequencies a little different. The Sony processor clocks at 2.5GHz with a comparison to the 2.7GHz processor. Additionally, the Xperia Z3 uses an Adreno 330 graphics processor in place of the Adreno 420 graphics processor in the Nexus 6. With 3GB RAM in each smartphone, there is absolutely no reason to complain in this regard. Supporting 16GB internal storage, the storage area in the Z3 can be enhanced to a maximum of 128GB using the appropriate memory card. With Nexus having never believed in offering provision for a memory card slot, the Nexus 6 comes in two variations – 32GB and 64 GB – to meet the user’s requirements.

The Xperia Z3 rolls out with Android’s KitKat installed as its operating system. However, this can be upgraded to Lollipop. The Nexus 6 already comes with the current version of Android, namely Lollipop.

Verdict: The very slight difference in clocking frequency does not affect the performance of the Sony Xperia Z3. However, a more powerful graphics processor and the capability of external memory expansion take it a step ahead.
