Following weeks of leaks, Sony has officially announced its Xperia Z4 smartphone – but appears to be limiting the roll-out to Japan. Like other Xperia phones, it is water- and dust-resistant, with IP68 protection.
The new phone is similar in design to the Z3, but is both thinner (6.9mm) and lighter (144g). Although the battery is smaller than some of today’s flagship phones (2,930mAh), Sony says that the Z4 will run for 17 hours of talk time.
In line with earlier rumours, the phone has 1920 x 1080 resolution and an octa-core Snapdragon 810 processor. Its screen is 5.2″ (rumours had claimed 5.1″), with 3GB of RAM and 32GB of storage (expandable to 128GB). The OS is Android 5.0, and the phone uses Sony’s Triluminos technology.
Sony has built the Z4 with an aluminium body. The handset features a waterproof USB port, eliminating the need to manually seal the port before dropping the phone in water.
Sony announced the Z4 at a Japanese press conference, but there was no word on a global roll-out. It will be available in Japan this summer.
