Sony has revealed the Xperia Z5 series of top-end smartphones at IFA 2015. The Japanese firm has loaded the trio of devices - the Xperia Z5, Xperia Z5 Compact and Xperia Z5 Premium - with what it says are market-leading cameras, as well as fitting the Xperia Z5 Premium with the first 4K smartphone display.
The main Xperia Z5 measures 146x72x7.3mm and features a 5.2in FHD screen, Qualcomm Snapdragon 810 processor with 3GB of RAM and a 2,900mAh battery. The rear camera is a new 23MP design with a shutter speed of 0.03 seconds, and is capable of recording 4K video. This camera also appears in the Xperia Z5 Compact and Z5 Premium, as does a more modest 5MP front-facing camera with 1080p video capture.
The power button on the side of the Xperia Z5 also acts as fingerprint sensor, which can be used to biometrically unlock the handset. Like the cameras, this feature is present across the entire series.
The Xperia Z5 Compact is the smallest of the three, measuring 127x65x8.9mm and equipped with a 4.6in, 1280x720 display. It includes less RAM than the Xperia Z5 at 2GB, and is powered by a smaller 2,700mAh battery but uses the same Snapdragon 810 CPU as its larger sibling.
The Xperia Z5 Premium is the biggest of the series at 154x76x7.8mm, and the most highly-specced. Its 5.5in screen is set at a colossal 3840x2160 resolution, with a 3430mAh battery fitted to compensate. Like the Xperia Z5, it incorporates the Snapdragon 810 processor and 3GB of RAM. Prices for the three smartphones have yet to be announced, but the Xperia Z5 Premium is sure to be the most expensive.
All three handsets will launch with Android 5.1 Lollipop, and meet the IP65 and IP68 dust and waterproofing specifications. They come with 32GB of internal memory, expandable with a huge 200GB of microSD storage, and are compatible with 4G LTE. In addition, the Xperia Z5 and Xperia Z5 Premium will support dual SIMs in certain markets.
Sony's decision to equip the series with the Snapdragon 810 is unexpected, as it is known for overheating, a serious problem we came across in our Xperia Z3+ review. Instead of swapping out the processor, Sony has instead focused its upgrade efforts on the Xperia Z5 line's cameras and, in the Xperia Z5 Premium's case, display.
We'll find out whether this strategy pays off when the Xperia Z5 and Xperia Z5 Compact launch worldwide in October. The Xperia Z5 Premium is scheduled to release a few weeks later in November.
