With the first 4K display phone, the Xperia Z5 Premium, Sony has kept its signature Xperia flagship design concept overall, with "frosted" glass and metal frame, but has introduced some new twists on the Z5 Premium, such as swapping the circular OmniBalance power / lock key with an elliptical ones, and for a good reason.
The flagship is outfitted with a fingerprint scanner there, which is arguably the most ergonomic place to put it, going all the way down beneath the display, or even on the rear. While Sony's phones are not the first to come with such a side sensor (Honor 7i was the first), they are the first brand-name phone maker that will obviously utilize those en masse, as both the Z5 and Z5 Compact are graced with one , too.
The Xperia Z5 Premium is a tad on the large side for a 5.5-incher at 154.4 x 76.0 x 7.8 mm, and quite hefty at 180g., Yet you are getting a premium waterproof chassis, and a large 3430 mAh battery that can keep the 4K phone going for Sony's typical two days of endurance, so no complaints.
