Sony Xperia XZ Premium: A great smartphone but it isn't as good as the Samsung Galaxy S8 and is now more expensive

Very fast performance; Doesn't smudge; despite glass front and back; Love that 960fps slow-mo funtion

Dated design; Sharp corners rip holes in your pockets

What is a ‘premium' smartphone? A spec machine: something packing top-of-the-line hardware, featuring a refreshing design, and of course, placed on the higher side when it comes to price, is something you can call a premium smartphone.

At $800, the Sony Xperia XZ Premium is one of the costliest flagship phones you can buy. In terms of hardware, it matches most of its rivals with smooth, fast performance, excellent camera quality, and high-resolution audio. It also has the sharpest display of any smartphone available.

Poor battery life; Fingerprint sensor not activated in US; Limited 4K HDR content; Bulky design

It's hard to take your eyes off of the unlocked Xperia XZ Premium ($799.99). It's the first phone with a 4K HDR display, packing a staggering number of pixels into a 5.5-inch panel. It also has a powerful Snapdragon 835 processor, high-resolution audio, stereo speakers, and a waterproof build. That said, the overall design is a bit dated compared with competing flagships that pare down the body while expanding screen size, and the phone's fingerprint sensor is disabled for US users. There's also little 4K HDR content available to take advantage of that gorgeous screen. The XZ Premium offers a lot to like, but the Samsung Galaxy S8 remains a more well-rounded alternative and our Editors' Choice. A Dated Design The Xperia XZ Premium doesn't surprise in terms of design. Available in black, chrome (silver), and pink, it's practically identical to the Xperia XZ, with the same rectangular shape, rounded sides, and unfashionably large bezel. In an era of phones with edge-to-edge display...

The Sony Xperia XZ Premium is a powerful unlocked phone that combines a vivid 4K HDR display with the latest Snapdragon processor and strong audio capabilities, but falls short in other areas.

The Xperia XZ Premium is a glorious return to the flagship segment. While the headline grabbing features, such as the super slow motion camera, have, let's say, limited usefulness, the phone behind them is very competent.

Sharp; colourful screen; Solid build; Fast

Massive horizontal bezels; Expensive; Camera poor in low light

Excellent display with HDR and 4K. Likes the design on the phone. Personally, bez bezels are no worries. The phone is also really fast but a great camera with super slow motion. + battery time + good screen + camera with super slow motion

The Sony Xperia XZ Premium is a premium-spec version of the XZ, with a 4K HDR screen, a next-gen processor, enhanced camera, more memory and a bigger battery. It's a beauty for sure, and not over-priced, but may be too big for some users.

The Sony Xperia XZ Premium is the best smartphone Sony has to offer, but it's still substantially behind competing devices like the Samsung Galaxy S8.

Unique looks; Good display; Fast

Sub-par battery life; 4K display and 960fps slo-mo are gimmicks only
