The tablet's greatest asset is its truly remarkable battery life

A 4,500mAh battery can be found at the back of the Xperia Z3 Tablet Compact. Sony promises up to 990 hours (41 days) of battery life in standby mode and up to 15 hours of video playback, which sounds decent enough doesn't it? Judging from our past experience with the Xperia Z3 and the Xperia Z3 Compact, which rocked our battery hall of fame, we expected the Z3 Tablet Compact to be a top-performer as well.

We weren't wrong – Sony did it again! The device clocked in at 9 hours and 48 minutes in our custom battery test, making the Z3 Tablet Compact the most durable tablet we've tested so far, almost on par with the Xperia Z3 Compact and slightly ahead of the Xperia Z3. As far as the tablet's rivals are concerned, the Google Nexus 9 remains at the second place with 9 hours and 24 minutes, while the bronze goes to the Samsung Galaxy NotePRO 12.2. Sony's supremacy in the battery department gets proven yet again, and we can only commend the manufacturer for stepping its game up in this department as well.

This mesmerizing performance takes its toll, however – in order to charge the Xperia Z3 Tablet Compact from 0% all the way to 100%, you'll have to wait roughly 4 hours and 42 minutes. Nonetheless, this is a price we are quite willing to pay.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Without a doubt, Sony has put a lot of engineering effort in its latest slate and the results are visible. To sum things up, we get an extremely compact, light, and water-proof tablet that has an outstanding battery life and most of the bells and whistles you'd expect from a tablet as per late 2014's standards. If we disregard the color inaccuracy of the display, this 8-inch champ could very well be one of the best slates you can throw your money at now. However, we can't simply omit the fact that Sony has once again spread itself thin and failed to deliver in this pretty fundamental aspect.

The slate is not quite popular yet, and is only available in certain markets across the globe. The most basic version of the slate - the 16GB Wi-Fi-only one - retails at £329 (~ $526) in the UK, whereas the 32GB Wi-Fi-only version and the 16GB LTE/Wi-Fi one can be yours for £379 (~ $606) and £ 429 (~ $686), respectively. Overall, we would say that it's one of the best 8-inch slates available on the market at the moment. Its closest rivals are the Apple iPad mini 3/iPad mini 2, the Samsung Galaxy Tab 4 8.0, and the LG G Pad 8.0. The Apple iPad mini 3, for example, offers more premium build (not water-proof, though) and sports a more accurate display for a slightly-lower price tag. The Galaxy Tab 4 8.0, on the other hand, is not as power-laden and compact, not to mention water-proof, but it flaunts a more affordable price tag and might be considered as a viable alternative to Sony's new tablet. Another offering in the same price range from Samsung, the 8.4-inch Galaxy Tab S 8.4, is a fierce rival, too – it sports a rather color-accurate Super AMOLED display with an extremely high pixel density (for a tablet, that is) and compact size. To sum things up, the Sony Xperia Z3 Tablet Compact is a good all-around tablet that will probably not disappoint.


  • The most compact and lightweight 8” tablet on the market
  • Slim, water-proof body
  • Fingerprint-free back cover
  • Powerful and future-proof hardware setup
  • Great battery life


  • Inaccurate display
  • Camera is under-performing in most real-life situations
