The XZ Premium is far from a one-trick phone, however. This handset sports the latest Qualcomm Snapdragon 835 processor, one of the most powerful mobile chipsets around. Performance is so fast that our hands practically blistered, while connectivity is fully future-proofed.
The XZ1 is kind of a brilliant hybrid of last year's Xperia XZ (see below) and the fresher Xperia XZ Premium. While the look and feel will be familiar to XZ owners, you get some of the best features from the mighty Premium model packed inside the Xperia XZ1. That includes HDR video support (although you don't get Ultra HD resolution visuals here) and the brilliant MotionEye camera, complete with that excellent Super Slow Motion mode.
The Xperia X is a premium handset like the Xperia Z5, with a few little cuts to trim down the price and undercut rival flagships like the Galaxy S7. Gone is the water resistant design and you get a less powerful processor compared with most premium 2016 phones, but the best-in-class camera is still on board and the X's selfie cam is particularly impressive - check out our Xperia X camera review for more info.
