Hardware

Design and Build

Sony refreshes the trademark ''Xperia Loop Surface'' design for the Xperia XZ1. But instead of using glass surfaces like the Xperia XZ Premium, the XZ1 is mostly consisted of a wraparound metal chassis, making up the back and sides of the device, with subtly-curved nylon top and bottom edges giving a more smoother approach to the overall design. The most defining change in the XZ1 as well as the XZ Premium is the placement of the image sensors at the back. It is now arranged across the camera lens, centered along the top, as opposed to being longitudinally placed below the lens like on the XZs. But unlike the XZ Premium which has a glass back panel, on the XZ1, the NFC antenna is housed alongside the image sensors, placed directly at the center of the glass window.

It has an IP rating of IP65/68, making it dust-proof and water resistant for over 1.5 meters and 30 minutes. 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 XZ1 is one of the first smartphones with an HDR display. But unlike the Xperia XZ Premium, the Xperia XZ1 abandons the 4K UHD resolution, settling for a 1080p FHD display instead. It is HDR10 compliant just like the XZ Premium, but has no

for smartphones. Known as the Sony IMX400, the sensor features a RAM chip sandwiched in between the sensor and control circuitry layers which serves as a large and fast buffer to where the sensor can temporarily offload a significant amount of captured data before transferring it to the phone's internal memory for processing. This enables the camera to record super slow-motion videos at 960 fps, at a steady 720p resolution. Recording at super slow motion is limited to 0.18 seconds per buffer though, due to limitations. The Xperia XZ1 borrows the Motion Eye Camera from the Xperia XZ Premium and XZs. It comprises a 19 MP 1/2.3” Exmor RS for mobile sensor with a 1.22

It utilizes the IMX400's built-in DRAM to offload captured data before being combined and built up in the proprietary 3D Creator application, creating a near-perfect rendition of the subject, be it a face of a person, a whole head or any object the user may wish to capture. The user is then given the option to use the rendered 3D image on the included animated figures for a more creative approach or have it 3D-printed by Sony's approved 3D printing companies, all within the app itself.

. 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 XZ1 comes with a standard 3.5 mm audio jack for plugging in wired headphones. It also has improved LDAC, an audio coding technology developed by Sony, that enables the transmission of 24bit/96 kHz High-Resolution (Hi-Res) audio content over Bluetooth at up to 990 kbit/s, three times faster than conventional audio streaming codecs, to compatible audio devices. Other connectivity options include Bluetooth 5 with aptX and Low Energy, NFC, dual-band Wi-Fi a/b/g/n/ac with 2x2
