Sony Xperia Z5 Premium Dual
Sony’s Xperia Z5 range consists of three models: the Z5 Compact (4.6-inch), the Z5 Dual (5.2-inch) and the Z5 Premium Dual (5.5-inch). But an extra 0.3-inches isn’t all that sets the Z5 Premium Dual apart from its siblings. It also has a shinier finish and amazingly, a UHD display.
Design-wise, the Z series has had only marginal changes over the years. The Z5 Premium Dual’s minimalist, boxy design features front and rear panels made of Gorilla Glass 4 plus a metal frame with plastic corners. Why the plastic? If you drop the phone, the plastic corners will absorb impact rather than directing pressure inwards (like metal), which would shatter the screen or rear glass. The Z5 Premium Dual continues the waterproof tradition of its predecessors, with similar capless ports and IP68 rating of the Z3+.
A new addition on the Z5 Premium Dual is a fingerprint scanner. Gone is Sony’s signature round power button; in its place is an oblong power button that looks slightly awkward, as stylish, but doubles up as a fast and accurate fingerprint scanner. Its position on the side lets you grab the phone out of your pocket and already have it unlocked by the time you’re looking at the display.
The Z5 Premium Dual’s main selling point is its 3,840 x 2,160 pixels display. That’s 806 ppi, which, for a 5.5-inch phone is quite honestly ridiculous. At this size, it’s completely impossible to tell the difference between a QHD (or even Full HD) display and the Z5 Premium Dual’s UHD display. On top of which, most of your video content is likely to be Full HD resolution at best. While there’re loads of 4K content on YouTube, the YouTube mobile app itself only lets you select up to 1080p. Even Sony’s own video store only lets you buy Full HD movies for the Z5 Premium Dual. Obviously you can load your own 4K content, but a one and a half hour movie is going to eat around 100GB of storage.
Quality-wise, the Z5 Premium Dual’s display is pretty great. Blacks are deep and colors are vivid and bright, although they’re nowhere near as good as the Note5 or Nexus 6P’s AMOLED panels. As with other Xperia phones, white balance is a bit on the cool side by default, but you can tweak this manually in the Settings menu.
The Z5 Premium Dual is powered by a Qualcomm Snapdragon 810 octa-core processor with 3GB RAM. It only has 32GB internal storage, but does come with a microSD slot that supports cards up to 200GB (for all that 4K content you’ll want to load on your phone).
