Can't decide between the XZ1 and the XZ1 Compact? You're in luck - we've put them head-to-head so you can discover which is the perfect device for you.
Sony Xperia XZ1 & XZ1 Compact Design
The XZ1 range is simply stunning. Both the XZ1 and XZ1 Compact are seamlessly smooth, while the rounded surface and metallic finish create a truly premium feel. The XZ1 Compact weighs in at just 143g, while its big brother tips the scale at 156g.
Sony has made sure both smartphones are durable enough for everyday use. Gorilla Glass is tough enough to handle the average tumble, and with an IP65/65 water and dust resistance rating, rainy days won't be a problem.
The Sony Xperia XZ1 and the XZ1 Compact have the honour of being the first Sony smartphones with Android Oreo pre-installed.

Sony Xperia XZ1 & XZ1 Compact display
There are two major features that set the display of the Sony Xperia XZ1 and the XZ1 Compact apart. The first, and the most obvious, difference is size. The flagship XZ1 is the largest, measuring 5.2 inches while the XZ1 Compact measues in at a handy 4.6 inches. The XZ1 offers a Full HD screen, which boasts extraordinary colour and clarity. In fact, you'll find the same technology on Sony's BRAVIA TVs, so it's no surprise videos and images are astonishingly natural-looking.
The XZ1 Compact, meanwhile, rocks a HD display. Both handset displays look brilliant, however the XZ1 is slightly sharper and more defined owing to a higher pixel density (424ppi vs 319ppi). The XZ1 and the XZ1 Compact both have a TRILUMINOS display and use Sony's X-Reality technology which helps low-resolution content look crisp and clear by reducing noise, enhancing texture and intelligently replacing missing pixels.
Sony Xperia XZ1 & XZ1 Compact power
Fuelling each device, you'll find 4GB RAM and a powerful processor to keep things running smoothly, even when running multiple apps. The only difference here concerns the amount of storage space available - the XZ1 Compact offers 32GB, while the XZ1 has 64GB on board. Both are expandable with a MicroSD card to 256GB however, meaning extra space for apps, photos and other content.
When it comes to charging, you'll be supported by a 2,700 mAh battery on either handset. Quick charging is ready to assist, and Smart Stamina mode helps you to get the most out of your remaining power by intelligently disabling unnecessary functions.
Motion Eye camera
You'll find Sony's ground-breaking Motion Eye camera (as debuted on the Xperia XZ Premium) built into both the Sony Xperia XZ1 and XZ1 Compact. Less noise, more detail and faster processing is guaranteed. You can record in super slow motion at 960 frames per second, or catch a moment before the shutter button is even pressed with Predictive Capture.
An impressive 19MP rear camera can be found on the XZ1 and XZ1 Compact, with SteadyShot to reduce blur. Sony's manual mode offers more freedom for budding photographers, letting you switch up the exposure, shutter speed and more. A 13MP selfie camera features on the XZ1, slightly larger than the 8MP front-facing camera on the XZ1 Compact. Both have a wide-angle lens, so you won't have to struggle to squeeze everyone into one shot.
Ever wish you could capture memories in 3D? Breaking boundaries, Sony's 3D Creator does just that, with innovative technology on both the Xperia XZ1 and the XZ1 Compact.
It takes just 15 to 60 seconds to fully scan an object or person directly, then you'll have a 3D, high-res avatar that you can save, morph, use online or even print via a 3D printer (if you're lucky enough to own one). You can even integrate your objects into the real world too with AR Effect.
Sony Xperia XZ1 & XZ1 Compact audio
Known for delivering amazing audio, Sony have also packed Hi-Res audio into the Xperia XZ1 and the XZ1 Compact. Digital Noise Cancelling technology creates a truly immersive experience, and the stereo speakers deliver 50% more sound pressure - making them the most powerful speakers to be used on an Xperia yet.
Still trying to make up your mind? If you're looking for smaller smartphone that still offers the specs of a premium device, the Sony Xperia XZ1 Compact will be perfect for you. However, if you love photography and fancy streaming videos on an extremely high-quality display, it's definitely worth investing in the Sony Xperia XZ1.
