Sony's recent addition to the fantastic Xperia line, the Xperia XZ Premium, boasts a smartphone first - a 4K HDR display. It's already making waves in the tech world, but how does it compare to its little brother, the Xperia XZ? And is it worth splashing out some extra cash for?
Here's how the two Sony devices compare side by side, and how they differ both in their appearance and under the hood.
Xperia XZ vs XZ Premium design
At first glance, you'll instantly notice that the Xperia XZ Premium is bigger and slightly sleeker than the XZ.
The XZ Premium rocks a 5.5-inch display, making it slightly larger than the 5.2 inch XZ display, and is protected by Corning Gorilla Glass 5. It's a little heavier - weighing 30g more than the regular XZ - but dispite the larger display it's actually 0.2mm thinner than the standard model.
The seamless design is finished off with beautifully curved edges, a high gloss finish, and IP68 waterproof rating.
Xperia XZ vs XZ Premium display
While the Sony Xperia XZ has a brilliant full HD display with curved glass, it's outshined by the Sony Xperia XZ Premium. The major difference between the two devices is the incredible 4K HDR display on board the XZ Premium; the same tech Sony uses in Bravia TVs.
With 4K, you'll be able to view content with more clarity than ever before. Images appear brighter and more vibrant, offering a truly unique mobile viewing experience.
Xperia XZ vs XZ Premium specs
Behind the scenes, you'll find a range of impressive specs fuelling both the Xperia XZ and the Xperia XZ Premium.
Both devices run on Android 7 Nougat, but their cores differ slightly. The Xperia XZ Premium features 4GB of RAM, and Qualcomm Snapdragon 835 Octa-core processor. The Xperia XZ has a slightly less advanced spec, with 3GB of RAM, and Qualcomm Snapdragon 820 quad-core processor.
When it comes to storage, both smartphones are upgradable to 256GB with a MicroSD card.
As for the battery, the XZ Premium features a 3,230 mAh power pack while the XZ offers a 2,900 mAh (which is roughly 17.5 hours of talktime). This difference isn't too surprising, however the XZ Premium will need more power to fuel that 4K display.
Xperia XZ vs XZ Premium camera
Regardless of which device you prefer, both Xperia models offer incredible camera quality with some really innovative features.
On board the Xperia XZ, you'll find a 23MP camera with triple image sensing technology, capable of delivering a range of stunning shots. This advanced technology uses sensors to cover distance, track movement and help make every colour truer to real life. There's a remarkable 13MP front-facing camera as well - ideal for selfie lovers looking to upload pictures instantly to Instagram.
The Xperia XZ Premium also boasts the same 13MP front-facing camera, but the rear camera is 19MP. There's less pixels, but the XZ Premium offers something the XZ doesn’t, in the form of Motion Eye technology. Shooting videos at 960 frames per second, this super slow-motion function allows you see things the human eye usually misses.
Xperia XZ vs XZ Premium - which should I buy?
If you're a Sony fan and currently looking for a new smartphone, it's easy to feel torn between the two devices. When it comes down to deciding which of the Xperia range to go for, it really depends on your personal preferences. Budding photographers and tech enthusiasts will be keen to get their hands on the XZ Premium, but those simply looking for a fantastic device that's sure to be reliable and perform to an exceptional standard might prefer the XZ.
To buy the Sony Xperia XZ Premium outright is obviously a little pricier than a SIM-Free Xperia XZ, however, you'll be able to find some brilliant pay monthly deals across Mobiles.co.uk to make each smartphone more affordable.
