Here's a look at the phones we see as being the main competition for the Sony Xperia Z5 Premium…
Samsung Galaxy S7 Edge
Samsung's latest Edge phone is one of the more innovative phones you can buy right now, quite like the Xperia Z5 Premium. The Galaxy S7 Edge also comes with a 5.5-inch screen, but on Samsung's phone it's curved around the edges.
The Galaxy S7 Edge also has a lot more functionality compared to previous Galaxy Edge phones. It comes with a high-end spec including a Qualcomm Snapdragon 820 processor, 4GB of RAM and the return of microSD support.
If you're looking for something a little bit different to the rest of the phone market out there and don't think the Xperia Z5 Premium is the phone for you, why not try this?

Moto X Style
The Moto X Style sports a 5.7-inch 2K display, and it looks great in the hand. You can also customise the handset using the online Moto Maker tool, so you don't have to stick to the basic design, as is the case with the Xperia Z5 Premium.
There's a 21MP camera as well, although it's not quite as good as the 23MP shooter on the Xperia Z5 Premium.
By far the most impressive thing about the Moto X Style is its price. You can get the 32GB version for £360 / $450 (about AU$615) – almost half the price of the Xperia Z5 Premium.

iPhone 6S Plus
Apple's second phablet incorporates its new 3D Touch screen technology, which gives you different functionality depending on how hard you press.
It's a great innovation, and offers new ways to interact with your phone – the tech hasn't been exploited by very many apps so far, but that will change.
The 5.5-inch screen is the same size as the Xperia Z5 Premium's, but the screen resolution is nowhere near as high, with the iPhone 6S Plus only managing 401ppi. That said, images still look great, so if you're into iPhones then this could be the phablet for you.

Sony Xperia Z5
Sony's Xperia Z5 is a great new addition to the Sony family, and gives you the impression that for once the company has stepped it up a gear and really improved its flagship phone range.
The glass back is frosted, and there are metal edges that make the design feel much more premium than previous Z-series phones.
The battery life of the Xperia Z5 is much better than the Premium version's, but the screen display isn't anywhere near as good, with only Full HD on offer here. But this phone is much more affordable, so don't go for the Premium until you've checked out little brother.
