Sony Xperia XZ
The Sony Xperia XZ is an Android smartphone manufactured and marketed by Sony. Part of the Xperia X series, the device was announced to the public along with the Xperia X Compact at a press conference held at the annual IFA event on September 1, 2016. The Xperia XZ was first released in Taiwan on September 30, 2016, with worldwide sales starting with the United Arab Emirates on October 1 and the United States the following day; its home country Japan only started sales on November 2, 2016.
The device is described by Expert Reviews as the "true successor" of the Xperia Z5 and the whole Xperia Z series, and was succeeded Xperia Z5 Premium and Xperia X Performance as Sony's flagship. It is succeeded by the Xperia XZs and the flagship Sony Xperia XZ Premium.
It is also one of the first smartphones manufactured by Sony to utilize USB-C connectivity for charging and data transfer. Compared to its predecessors, the rear camera of the Xperia XZ now has laser autofocus, a first for Sony, built-in alongside the hybrid contrast/phase detection autofocus also found on the previous flagship. It also the first Sony device to sport an RGBC-IR color sensor to assist the image sensor in capturing accurate colors, temperature and white balance and the first smartphone to feature a five-axis digital image stabilization system for capturing blur-free photos and videos. The phone also has an IP68 rating, with it being dust and water resistant.
Specifications
Hardware
The Xperia XZ's design consists of 3 different materials that seamlessly blend together in what Sony calls "Loop Surface": a nylon frame, scratch-resistant front glass and an aluminium alloy metal back. The rear cover of the device is made from an aluminium alloy marketed as ALKALEIDO, a trademark by Kobe Steel, specifically engineered to complement the smartphone's premium design with a material "that has an extra shine and a feeling of depth". The device's front side is covered in Gorilla Glass to protect it from scratches and high drops. Also up front are dual front-firing stereo speakers, one on top along with the front selfie camera, ambient light and proximity sensors and notification LED, and the other one at the bottom bezel.The Xperia XZ's dimensions are in height, with a width of and a depth of and weighs approximately. The device brings back the 1080p IPS LCD display with a pixel density of 424 ppi that started with the Xperia Z2 but with a brand new panel, featuring Sony's TRILUMINOS™ display and X-Reality for mobile technology. It is powered by a quad-core Qualcomm Snapdragon 820 chipset with 4 custom Kryo processors, 3 GB of RAM and relies on the Adreno 530 clocked at 624 MHz for graphics rendering. The device also has an internal storage of 32 GB for the single-SIM variant and 64 GB for the dual-SIM variant, both with microSD card expansions up to 256 GB.
The Xperia XZ antennas support up to a maximum of LTE Category 9 speeds with a maximum theoretical downlink speed of 450-500 Mbit/s using 3CA, excluding the SOV34 model whose maximum theoretical downlink 3CA speed is limited to maximum 370 Mbit/s.
Connectivity and Features
Unlike some recently released smartphones from competing brands, the Xperia XZ doesn't abandon the standard 3.5 mm audio jack in favor of wireless substitutes. It does, however, have LDAC, an audio coding technology developed by Sony, that enables the transmission of 24bit/96 kHz High-Resolution audio content over Bluetooth at up to 990 kbit/s, three times faster than conventional audio streaming codecs, to compatible audio devices. It also has the standard set of connectivity options like Bluetooth 4.2 LE with aptX, NFC, dual-band Wi-Fi with Wi-Fi Direct, DLNA and hotspot, GPS and A-GPS, GLONASS and BDS. Like its predecessors, it has an IP rating of IP68, making the Xperia XZ dust proof and water resistant for over 1.5 meters and 30 minutes under water. The device also feature a fingerprint sensor embedded into the power button that can be used to unlock the phone and secure it from unauthorized access. This feature is disabled by default in the US.Battery
The Xperia XZ is powered by a non-removable 2900 mAh battery, with a USB-C connector for charging and data transfer, one of the first two Sony smartphones to have one, the other one being the Xperia X Compact. It has QuickCharge 3.0 support 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 cell'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.Camera
The rear camera of the Xperia XZ features a new multi-aspect 24.8MP Sony Exmor RS image sensor, officially named as Sony IMX300. Similar to the Xperia Z5 series, the Xperia X and Xperia X Performance, it has 23 megapixels with a sensor size of 1/2.3 inch and a f/2.0 aperture. Sony introduces the Triple Image Sensing technology with the Xperia XZ, comprised by the Image sensing, Distance sensing and Color sensing systems. It features a hybrid autofocus that utilizes phase detection to lock focus on a subject within 0.03 seconds, also same with the Xperia Z5. It also includes phase and contrast detection along with predictive motion tracking, both working together to adjust the right amount of contrast accurately and significantly reduce blur and image shift caused by shaky hands.The Xperia XZ, for the first time, includes a laser autofocus sensor alongside the hybrid/PDAF in tracking and locking focus on an object faster than regular autofocus modes, and an RGBC-IR color sensor that assists the white balance function of the camera by providing additional data about the light conditions of the environment, thus improving the color accuracy of the image. It also has an upgraded SteadyShot with Intelligent Auto in addition to the 5-axis image stabilization. The front selfie camera has a 13 megapixel sensor with 22 mm and 90 degree wide angle lens, making it the highest-resolution front-facer on a flagship Sony device.
The device also has 4K resolution video recording capabilities like the Xperia Z5. Similar to the Sony α7 II camera, the Xperia XZ features five-axis digital image stabilization, a first for a smartphone, that helps in producing smooth video with less camera shake and improved image quality in low light environments. This technology improves the image and video produced by detecting camera shake, such as angular motion consisting of pitch and yaw, shift shakes which consists of X and Y axis shifts and by correcting the effects detected, shifting the lens to reduce visible image blur and shift shake.
