Sony launches Xperia Z5 Premium – complete with 4K screen
Sony has announced the world’s first smartphone with a 4K screen at IFA 2015. The Sony Xperia Z5 Premium is insanely pixel-packed, with its 5.5in 3840 x 2160 display equating to a staggering pixel-per-inch count of 808.
Whether or not this resolution is necessary remains to be seen, but at least Sony’s promised that its fabled two-day battery life won’t be affected by pushing all those pixels. There’s very little 4K content out there at the moment, but the Premium is able to upscale videos to the higher resolution to compensate. Our final review will determine whether or not it’s worth paying extra for the privilege of gloating at the pub, so stay tuned. The announcement goes some way to making up for the slightly underwhelming Sony Xperia Z3+, and from what we’ve seen of it Apple, Samsung, HTC and LG had better start worrying.
The Xperia Z5 is the standard issue flagship model and comes with a 5.2in, 1080p display, while the Z5 Compact caters to smaller-handed gadgeteers, with a 4.6in 720p screen. All three handsets share the same internals, namely a Snapdragon 810 processor (with the overheating problems hopefully ironed out), 3GB of RAM, and support for microSD expansion (take that, Samsung). One major change to the Xperia lineup is the new longer, flatter power button which is present in all three handsets. Not only does it look sleeker, but it houses a fingerprint sensor, positioned on the side for easy access with your thumb. We tried out this new sensor during our hands-on review of the Xperia Z5 Compact, and found it to be as accurate and as fast as the alternative offerings on the iPhone 6 and Samsung Galaxy S6.
