Sony Xperia XZ Premium

Flagship performance ; High resolution display ; Decent speakers

Dated design ; Uncomfortable to hold ; Slow-motion feature video is limited

4K display is stunning ; Great camera ; Solid battery life

Design isn't the most premium ; Fiddly SIM tray ; Lack of 4K content lessens screen's impact

The Sony Xperia XZ Premium has everything you want when paying top dollar for a phone, with its 4K display and slow motion camera two standout party pieces. It will please Sony fans around the world.

Sharp, colourful screen ; Solid build ; Fast

Massive horizontal bezels ; Expensive ; Camera poor in low light

Great 4K display with HDR technology ; Good battery life ; Super slow-motion feature is excellent ; Good overall software experience ; Waterproofing ; Cheaper than some other flagships

Design hasn't moved on much ; Camera isn't as good as competition ; Display doesn't manage well in super bright conditions ; Occasional lag in performance

The Sony Xperia XZ Premium is every bit the flagship smartphone in terms of spec, but it doesn't bring the same wow factor as the likes of the Samsung Galaxy S8 or LG G6.

The Sony Xperia XZ Premium is a stunning smartphone, both in terms of design and performance. The mirror-like look isn’t for everyone due to the appearance of smudges, but it helps provide an elegant, high-end look.

Class-leading display ; Exceptional camera ; Top-notch performance ; Smart battery technology

No one-handed mode ; Fingerprint magnet ; Expensive ; Heavy

For most people, the Xperia XZ Premium’s headline features are more party pieces than key reasons to buy it, but even without them, this is a truly solid top-tier flagship..

Superb display; Solid camera; Nifty features; Powerful processor

Average design; Cluttered UI

Armed with a great display, feature-rich camera and powerful processor, the XZ Premium should be hands-down the best smartphone around at the moment right?

The best resolution we've seen on a smartphone; Unique design; Good camera;

4K smartphones are still fairly redundant; Screen-to-body ratio isn't good; Battery life is disappointing;

The Sony Xperia XZ Premium is the best 4K smartphone out there. It's still more than a little pointless, of course, but it's hard to deny that it looks very good.

Let me pin my colours to the mast one more time, just in case I wasn’t clear before: a 4K screen on a phone is silly. It’s innovation for innovation’s sake, rather than practically useful. The human eye can’t tell the difference on such a small screen.
