Sony Xperia Z4 gets certified by Japanese wireless authority

16 January, 2015

While CES has been the traditional scene for new Xperia Z announcements, this year the company seems to be keeping its ace for the Mobile World Congress. Meanwhile, the Xperia Z4 has been certified in its home country in three versions – NTT DoCoMo, KDDI and SoftBank.

Al three support LTE, including VoLTE, which is the new generation in voice call technology and is slowly gaining support from carriers. The phones also support Wi-Fi a/b/g/n/ac.

The new flagship is expected to keep the defining features of the Xperia Z3 – a 5.2" Triluminos display, water resistance and the traditional Xperia design language. The new flagship will most likely be powered by a Snapdragon 810 chipset, which will bring Cat. 9 LTE connectivity, that's 450Mbps.

The Xperia Z4 Ultra and Z4 Compact will use the same chipset, but they will have screen sizes that are polar opposites – 6.44" and 4.7". The Xperia Z4 Compact will have the usual 20.7MP camera, a 5MP selfie camera, and a whopping 3,000mAh battery. The bigger Xperia Z4 Ultra will have a 16MP camera, 3,500mAh or 4,000mAh battery.
