The Sony Xperia Z4 Tablet was released during June 2015 comes with a large 10.1-inch display that looks custom-made for multimedia content viewing. We were on the lookout for a good slate for watching movies while undertaking a long travel from office to home hence we decided to test out the Xperia Z4 large-screen slate.

We also subjected the Sony Xperia Z4 Tablet to multiple performance tests. Check out, how the slate performed in our tests, below:

Design and Display

The Sony Xperia Z4 Tablet looks compact, it is thin as it has a thickness of just 6.1 mm. Dimensions-wise, the device measures 254 x 167 mm and weighs in at a bulky 393 grams. The power button is located to the left whereas on the right-hand side users will find the microUSB port.

USP of the Sony Xperia Z4 Tablet’s design is its waterproof nature. We subjected the device to waterproofing tests but did not spray powerful currents of water; upon spraying only a couple of jets of water in a mild manner, we found that the handset retained its active state without undergoing any visible changes.

Upon using the Sony Xperia Z4 Tablet, we found that the device’s externals are robust.

As far as the actual display is concerned, the Sony Xperia Z4 Tablet features a 10.1-inch LCD capacitive touchscreen that has resolution of 2560 x 1600 pixels with pixel density of 299 ppi.

When we used the tablet outdoors, in full sunlit conditions, the display passed off as good considering the fact that were clearly able to read the contents on the screen. Even rendered images were sharp without getting pixelated.

When the Sony Xperia Z4 Tablet was used in low-light conditions to read eBooks by the bedside, the experience came off as comparatively good.

Finally, the on-screen navigation also seemed a pleasure.

Processor and Memory

The Sony Xperia Z4 Tablet incorporates a Qualcomm Snapdragon 810 SoC that consists of a 1.5 GHz quad-core Cortex-A53 and a 2.0 GHz quad-core Cortex-A57 CPUs and an Adreno 430 GPU.

During our testing, multitasking seemed a pleasure to be honest. We also tested the slate by establishing a multi-app scenario as well. The Snapdragon 810 responded perfectly to user inputs and we also feel that the instruction processing capabilities of the SoC are fairly good considering the fact that both simple and relatively compound tasks took lesser time to be completed. There were absolutely no major glitches/performance lags during our time with the Xperia Z4 Tablet.

The 3 GB RAM, working in tandem with the Snapdragon 810 ensures that running games such as Dead Trigger 2 are a pleasure.

The Sony Xperia Z4 Tablet offers users a 32 GB internal storage that can be expanded till 256 GB via an external microSD card slot.


The Sony Xperia Z4 Tablet offers an 8.1 MP rear camera that comes with autofocus capabilities. This shooter lets users shoot 1080p videos at 30fps. Daylight imagery was fairly good during our testing, but shooting and recording images in low-light conditions was just average.

Apart from the 8 MP rear camera, there is also a 5.1 MP front camera that is custom-made for interactions via video calls. Images captured via the secondary camera are above average but low-light ones are disappointing with increased white balance and pixellation.


The Sony Xperia Z4 Tablet variant that we got to review, ran on the older Google Android 5.0 (Lollipop) operating system. This is however upgradeable to the much newer Android 6.0 (Marshmallow) when the firmware begins its seeding process.

The overall UI of the Xperia Z4 Tablet came across as relatively intuitive and efficient.

Battery Life and Verdict

The Sony Xperia Z4 Tablet derives its power from a 6,000 mAh Lithium-Polymer battery.

The battery backup obtained, during our testing lasted nearly 10 hours when we watched videos and streamed these. But when usage is restricted to basic (that includes editing documents and basic internet), the battery backup time rose significantly (to more than 10 hours).


The Sony Xperia Z4 Tablet impresses with its design and display. Upon using the slate, we are of the opinion that the device is intended at the first-time Android adapters in mind.


In the UAE, the Sony Xperia Z4 Tablet is priced at AED 2,300. This price tag is exorbitant considering the key technical specs offered by the slate.


Amazing display. Fast performance
