Sony unveils the Xperia Z5 Compact, Xperia Z5, and the Xperia Z5 Premium with a 4K display

Sony Xperia Z5

At a press conference in IFA today, Sony unveiled a trio of flagship handsets in different shapes and sizes: the Xperia Z5 Compact, Xperia Z5, and the Xperia Z5 Premium. Building on its previous flagship handset, the Xperia Z3+/Z4, the Z5 series comes with improvements in some key areas.

All the three phones are almost the same, except for their displays and thinness. While the 8.3mm thick Z5 Compact comes with a 4.7-inch 720p display, the 7.3mm thick Xperia Z3 features a 5.2-inch 1080p display. The Z5 Premium, however, steals the show with its 5.5-inch 4K display. This means that the handset has a pixel density of 801ppi, which is ridiculous in anyway you see it.

Under the hood, the handset is powered by a Snapdragon 810 chipset and packs in 3GB RAM. There is also 32GB of storage space, a microSD card slot, and the usual array of connectivity options. The Z5 Compact only comes with 2GB RAM though. The power button located on the side of the phones also features an integrated touch-based fingerprint scanner. The Z5 Compact comes with a 2,700mAh battery, while the Z5 and Z5 Premium come with a 2,900mAh and 3,340mAh one, respectively. Sony says that all the three handsets are capable of lasting “up to two days” on a single charge.

As for the camera, the Xperia Z5 series of handsets come with a new sensor from Sony with a 23MP resolution, which the company claims features the “world’s fastest autofocus in a smartphone” with a focus time of only 0.03 seconds thanks to embedded phase-detection pixels. The 1/2.3-inch sensor is placed behind a six-element 24mm lens with an F/2.0 aperture and is housed inside a closed-loop actuator that will offer better image stabilisation.

On the software front, all the three handsets run on a near stock build of Android 5.1.1. Sony has basically given up on its Android skin and has decided to go with a near stock build of Android on its devices going forward.

The Xperia Z5 Compact and Xperia Z5 will be available globally from October 2015, while the Xperia Z5 Premium will be available from November 2015.
