The Sony Xperia Z4 Tablet faces the daunting task of flying the Z4 banner, when the Xperia Z4 smartphone is just an incremental update limited to the Japanese market. The 10.1-inch tablet seems up for the task however with contemporary specs, attractive styling and razor-thin profile.

The Xperia Z4 Tablet builds on the virtues of the Z2 Tablet from a year ago and the improvements are much easier to spot than in the Xperia smartphone range where Sony's twice-a-year release cycle has meant more gradual evolution.

We weren't particularly satisfied with the low 224ppi of the predecessor, rather thin even by last year's standards and we're happy to note that the tablet's display resolution has been brought up to date and is now 2,560 x 1,600 pixels.

Sony's design language has remained unchanged for a while, and while it may be getting a bit tired, it's stylish nonetheless. A few excess millimeters have been trimmed off the footprint, while thickness has been brought down to match the Apple iPad Air 2 at 6.1mm. And perhaps most importantly, an IP68 certification means you can submerge it in water for up to 30min and 1.5m in depth, without fearing for its life.

Most impressively, the tablet weighs just 393g, a good 10% lighter than both the predecessor and the Cupertino rival. Meanwhile, battery capacity hasn't been sacrificed and has remained at 6,000mAh, but will that be enough to power 80% percent more pixels and more capable chipset?

Speaking of chipsets, a whole year warrants an improvement in the innards and the Snapdragon 810 has replaced the S801 of the Xperia Z2 Tablet. We're only left to hope that Sony has managed to leverage the large surface area to benefit the heat dissipation and we finally the Snapdragon live up to its potential.

We have the LTE version of the tablet which comes with the added benefit of cellular connectivity. There's also a WI-Fi only model, but our findings should apply equally well to that one too. For the sake of simplicity we'll drop the LTE abbreviation for the rest of this review.

There's no way you have missed the Xiaomi Redmi Note 3. It's been the bang-for-buck benchmark for a while now, delivering a feature set and performance way above what its price tag suggests.

To refresh your memory Xiaomi launched the Redmi Note 3 at the turn of last year and it was powered by a MediaTek Helio X10. In the spring of 2016, a Qualcomm-driven Redmi Note 3 followed and broke the company's sales record in India. Now this full review admittedly comes a little late, but the Xiaomi Redmi Note 3 is still on many people's radar, so we figured a way to compare the Mediatek-powered original and the Snapdragon edition might come in handy.

Besides the chipset, there's also a new camera sensor, a 16MP unit even if it is limited to 1080p video recording. Another difference is the second SIM card tray can now take microSD cards. It's the hybrid kind, which isn't ideal for people who want to have it all. Other than that, the hardware is perfectly familiar.
