Sony Xperia Z5 Premium hands-on with 4K display

Today we're having a look at the Sony Xperia Z5 Premium with 4K display, deciding whether or not it makes sense to go this far with sharpness on a mobile display. This device has a 5.5-inch display panel, meaning you'll have 806 pixels per inch – far more than is discernible by the human eye. We'll have to try this device out for an extended period of time before we decide whether or not it'll be worth the "Premium" price it'll cost.

Meanwhile the device is very similar to previous Xperia Z devices with glass up front and around back and a metal rim around its edges. There is, indeed, a fingerprint sensor under its power button, and the word "XPERIA" is up inside the edge – otherwise Sony has stuck to its guns as far as design language goes here.

Below you'll see the full specifications of this device, including audio codec abilities and camera power. The camera, processor, and RAM – not to mention every other specification save the display and battery – are the same as the standard Z5.

This device comes in Chrome, Black, and Gold – that's also what makes it different from the standard Z5. You'll find that this machine's Premium nature lies solely in its display when compared to the Z5.

The battery is larger than the Z5, here, at 3430mAh, but with a far more dense display we'll expect the drain on said battery to be quick. Indeed even Sony suggests that the battery life on this device is the same as the Z5 despite its larger size (the Z5's battery is 2900mAh).

We'll see in the near future whether or not Sony ends up bringing this device – and the rest of its Z5 lineup – to the United States.
