Pre-orders for the Xperia XZ Premium started in Europe on 22 May 2017. The device went on sale in the UK on 2 June 2017 and in the US on 19 June 2017.
It serves as the spiritual successor of the Xperia Z5 Premium and is Sony's latest flagship after the Xperia XZ.
The device's highlight features are a 4K HDR ultra high resolution display and its capability of capturing super slow-motion videos at 960 frames per second.

Hardware
Design and Build
The Xperia XZ Premium refines the Xperia XZ's "Loop Surface" design. Called "Glass Loop Surface", it consists of a nylon side frame, metal top and bottom edges that together make up the chassis of the phone, and scratch-resistant front and back glass panels made of Corning's Gorilla Glass 5. The top and bottom part of the chassis are flat and diamond-cut along the edge to form a reflective facet. The front of the phone consists of dual front-firing stereo speakers, one on the top bezel and the other on the bottom bezel, along with a 13 MP front camera, ambient light sensor, proximity sensor and notification LED.
The Xperia XZ Premium's dimensions are 156 mm (6.1 in) in height, with a width of 77 mm (3.0 in) and a depth of 7.9 mm (0.31 in) and weighs approximately 195 g (6.9 oz). It has an IP rating of IP68, making it dust proof and water resistant for over 1.5 meters and 30 minutes under water. The device also features a fingerprint sensor embedded into the power button that can be used to unlock the phone and secure it from unauthorized access. This feature, however, is disabled on units sold in the US.
Display and Performance
The Xperia XZ Premium is the second phone with a 4K (2160p) display, the first one being the Xperia Z5 Premium. But unlike the latter, the Xperia XZ Premium has a 4K HDR display, making it the first smartphone to feature such a display. It is HDR10 compliant, but has no Dolby Vision support. The 5.46 in (139 mm) IPS LCD screen has a pixel density of 807 ppi and features Sony's TRILUMINOS(TM) display and X-Reality for mobile technology.
It is powered by the Qualcomm Snapdragon 835 (MSM8998), built on 10 nm process technology with 8 custom Kryo 280 processors (4x 2.45 GHz and 4x 1.9 GHz), 4 GB of LPDDR4X RAM and uses the Adreno 540 for graphics rendering. The device also has an internal storage of 64 GB and comes in single-SIM and dual-SIM versions, with both featuring LTE Cat. 16 with 3x carrier aggregation, a 4x4 MIMO antenna design and a total of 8 antennas. It also has microSD card expansion of up to 256 GB (in a hybrid slot for the dual-SIM variant).
Camera
Sony debuted in the Xperia XZs and the XZ Premium the world's first 3-layer stacked image sensor with DRAM for smartphones. Known internally as Sony IMX400, the new sensor features a RAM chip sandwiched in between the sensor and control circuitry layers, serving as a large and fast buffer to where the camera can temporarily offload photos or videos without waiting to store the captured data in the internal phone storage. This enables the camera to record super slow-motion videos at an unmatched (and a world's first for a smartphone) high frame rate of 960 fps at a steady 720p resolution, which is four times the speed of most flagship smartphones to date. Recording at super slow motion is only limited to 0.18 seconds per buffer though, about a blink of an eye, due to limitations.
Officially called Motion Eye(TM), the Xperia XZ Premium has a 19 MP 1/2.3" Exmor RS for mobile sensor with a 1.22 ?m pixel pitch, f/2.0 aperture and 25mm wide G Lens. It also features 4K video recording, which supports SteadyShot video stabilization alongside the standard 1080p/30fps and high-speed 1080p/60fps and a 120fps recording in 720p options. The front selfie camera has a 13 megapixel sensor (1/3.06") with 22 mm, f/2.0 lens and 90 degree wide angle lens, same as the Xperia XZ but now features SteadyShot(TM) with Intelligent Active Mode (5-axis stabilization) like on the XZs.
The Xperia XZ Premium is also backed up by Sony's Triple Image Sensing technology first introduced in the Xperia XZ, comprised by the Image sensing (CMOS sensor with PDAF), Distance sensing (Laser AF sensor) and Color sensing (RGBC-IR sensor) systems. It features a hybrid autofocus that utilizes Phase Detection (PDAF) to lock focus on a subject within 0.03 seconds, and also includes phase and contrast detection along with predictive motion tracking. Like the previous flagship, it has a laser autofocus sensor for tracking and locking focus on an object faster than regular autofocus modes alongside the RGBC-IR (RedGreenBlueClear-InfraRed) color sensor that assists the white balance function of the camera by providing additional data about the light conditions of the surrounding environment. It also has SteadyShot with Intelligent Auto in addition to the five-axis sensor-shift image stabilization first seen in the Xperia XZ.
The Motion Eye(TM) camera also has a new feature called Predictive Capture. When it detects fast paced movement, the camera automatically captures a maximum of 4 photos before the shutter button is pressed, and lets the user select the best one afterwards. This is done without any user intervention and is possible thanks to the same built-in RAM chip on the image sensor used in capturing its famed 960 fps super slow-motion videos.
Battery
The Xperia XZ Premium is powered by a non-removable 3230 mAh battery. Charging and data transfer is handled by a USB Type-C port with support for USB 3.1. It also has Qualcomm's QuickCharge 3.0 and Qnovo adaptive charging technology built-in. This allows the device to monitor the cell's electrochemical processes in real time and adjust charging parameters accordingly to minimize cell damage and extend the battery unit's lifespan. It also comes with Battery Care, a Sony proprietary feature, that controls the charging process of the phone by learning and recognizing the user's charging patterns, preventing the phone from damaging the battery's cells from excessive heat due to overcharging. For example, when charging overnight, Battery Care stops the initial charge to 90 percent and then continue charging until full where it left off the next day.
Audio and Connectivity
The Xperia XZ Premium still comes with the standard 3.5 mm audio jack for plugging in wired headphones. It also has LDAC(TM), Sony's proprietary audio coding technology that enables the transmission of High-Resolution (Hi-Res) Audio content wirelessly at up to three times faster than conventional Bluetooth Audio and without any down-conversion to LDAC-compatible audio devices. Standard set of connectivity options include Bluetooth 5 with aptX and Low Energy, NFC, dual-band Wi-Fi a/b/g/n/ac with 2x2 MIMO antennas for speeds up to 867Mbps, Wi-Fi Direct and hotspot, MirrorLink, screen casting via Miracast, Google Cast and DLNA, GPS and A-GPS, GLONASS, BeiDou and Galileo satellite positioning. The Xperia XZ Premium, like many others, has no FM radio.
