Sticking to its usual 6 months cycle, Sony has launched a new model in its high-end XZ smartphone line. The Xperia XZ3 follows on from the XZ2 which was released earlier this year. The new device is more evolution than revolution and the major differences to the XZ2 are an updated screen, a bigger battery and a slightly modified body design.

The new 6-inch OLED display supports HDR and comes with a 2880 x 1440 pixel resolution. It is protected by Gorilla Glass 5 that is curved at the edges to integrate smoothly with the aluminum body. The bezel dimensions have also been reduced, allowing for an improved display/body ratio.

Probably thanks to the marginally larger device body Sony has been able to use a beefier 3330 mAh battery which, compared to the XZ2's 3180 mAh unit, should deliver a slightly improved battery life. Sony has also improved the S-Force front speakers, offering better base and treble as well as a 20% increased overall volume.

At 1/2.3" the sensor is comparatively large for a smartphone camera and is combined with a 25mm equivalent wideangle lens and F2.0 aperture

Other specs include a Snapdragon 845 processor, 4GB of RAM and 64GB of storage, all wrapped up in a IP68 water and dust resistant body. At least on paper the rear camera specification has not changed for the new model and the XZ3 comes with the same 19MP camera module as the XZ2. At 1/2.3" the sensor is comparatively large for a smartphone camera and is combined with a 25mm equivalent wideangle lens and F2.0 aperture. Predictive PDAF, laser AF and 4K video recording are on board as well.

The front-facing unit has been updated, however, and now comes with a higher 13MP resolution and faster F1.9 lens. The Xperia XZ3 will b available from October 17 for $900. More information is available on the Sony Mobile Blog.
