Sony is an electronics giant with world-leading expertise in LCD displays, digital photography and audio. Since parting company with Ericsson, Sony has focused its attention on its Xperia range of Android smartphones, and has won praise (not least from us!) for the quality of its products.
Today's best buy: Sony Xperia XA1 from Currys (£169.99)
The Sony Xperia XZ Premium is a premium-spec version of the XZ, with a 4K HDR screen, a next-gen processor, enhanced camera, more memory and a bigger battery. It's a beauty for sure, and not over-priced, but may be too big for some users.
The Sony Xperia XA1 is a mid-range phone with premium styling. It's superslim and very narrow, with almost no bezels left or right of the screen. Equipped with 32GB of storage and a fast 8-core processor, it's not lacking in any department. But perhaps its top feature is its class-leading 23 megapixel camera.
The Sony Xperia XA is a beautifully-styled phone, with an "Infinity Glass" design giving it high-end looks at an affordable price. It's fast too, thank to its 8-core processor, and dual-core GPU. But the screen's resolution is on the low side, and battery life is challenged.
The Sony Xperia XZ is Sony's flagship phone for 2016. Slim and sleek, the XZ is a premium-build device running Android M and featuring a fast Snapdragon 820 processor with plenty of memory. Photography is a key strength too, thanks to its 23 megapixel camera with laser autofocus.
The Sony Xperia X is a high-end smartphone with a sleek, minimalist design. Boasting a 23 megapixel camera with hybrid autofocus, and a front-facing 13 megapixel camera, photography is a key strength. But the X is a solid all-rounder - fast, capable, and affordable.
The Sony Xperia X Compact is a high-end compact smartphone with a fast processor, outstanding camera and plenty of memory. Lightweight and easily pocketable, it offers most of the features of Sony's flagship devices. However there are a few compromises and it seems over-priced compared with the alternatives.
The Sony Xperia Z5 Compact offers a superphone experience in a compact form factor. With a 4.6-inch HD screen and a premium, lightweight build, the Z5 Compact is easy to handle, but delivers the power of an 8-core processor, a 23 megapixel camera with 4K video capability, and a two-day battery.
The Sony Xperia M5 offers most of the features of the flagship Z5, but for substantially less money. Its super-slim design is very nearly the same, and its 21.5 megapixel camera with 4K video makes the M5 one of Sony's best ever camera phones. The 8-core Helio X10 processor isn't quite as fast as the Snapdragon 810 used in top-end phones, and the memory is just 16GB, but for the price, we think that it offers exceptional performance.
The Sony Xperia L1 offers the biggest screen you'll find on an entry-level or mid-range phone. But that's its only real selling point. Everything else is very ordinary, and the phone is bulky and heavy too. But if it's a big screen you're after, the L1 is worth considering.
The Sony Xperia Z5 Premium's headline feature is its 4k screen - the first in any smartphone. But look beyond the headline, and you'll find one of the most glamorous phones of 2015, with killer features all round. Our heart was won over by the near-perfect design and mirror chrome finish. Our head was won by the Snapdragon 810 processor, 23 megapixel camera and ample storage. Overall, it's one of the very best phones of the year.

A match for the Galaxy S5 and HTC One M8!

Sony Xperia Z3 Plus review - We've been huge fans of Sony's Xperia Z series, and the Z3+ should have been another slam dunk phone. But massive overheating problems make this one to avoid. It's a shame, because in every other way, this is the best Sony smartphone ever.
