Latest reviews & news in Mobile phones
Most popular in Mobile phones:
|Samsung Galaxy S6 review|
The Samsung Galaxy S6 brings premium metal-and-glass looks to Samsung's winning formula of a high-spec Android smartphone. The S6 features a stunning quad-HD AMOLED screen, an 8-core processor, enhanced cameras, Android Lollipop and a wealth of other features. The only things holding it back are the lack of expandable memory, and the rather average battery life. Click for more
|Sony Xperia Z5 review|
The Sony Xperia Z5 has fixed the overheating problems that plagued the Z3+. It brings a new, less flashy design with a fingerprint sensor built into the power button, and sports an upgraded 23 megapixel camera too. It's one of the fastest smartphones available, with an excellent screen and plenty of memory. Click for more
|Apple iPhone 6s review|
The Apple iPhone 6s has a faster A9 processor, improved cameras, pressure-sensitive touchscreen, and is less prone to bending. It's basically an updated iPhone 6, and comes in new colour options too. As always, Apple has delivered a good product, but it's vastly over-priced. Click for more
|Samsung Galaxy S6 Edge review|
Just when you thought all smartphones looked the same, the Samsung Galaxy S6 Edge brings a fresh new look. Featuring a double-edged curved screen with special edge display features, it's one of the best-looking phones you can buy. It's also super-powerful, with an 8-core processor, outstanding cameras, plenty of memory and the latest Lollipop flavour of Android. But make sure you're sitting down before you look at the price!

|Sony Xperia Z5 Compact review|
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. Click for more
|Apple iPhone 6 review|
The iPhone 6 finally catches up with Android and comes with a big 4.7 inch screen and NFC cashless payments. It's probably the most beautiful, most practical, most desirable phone in the marketplace in 2014. Click for more
|Samsung Galaxy J5 review|
Samsung's affordable J Series phones are rolling out in 2015, and the J5 is a mid-range model with an attractive slimline design and solid, mid-range capabilities. Its best features are its HD AMOLED screen, decent camera and battery life. Watch out for the smallish 8GB of memory though. Click for more
|Samsung Galaxy A3 review|
The Galaxy A3 from Samsung is a mid-range phone with a premium metal design. It's compact, ultraslim, and exceptionally light in weight, and is quite possibly the nicest-looking phone you can own in this price category. Click for more
|HTC One M9 review|
The HTC One M9 smartphone looks almost identical to the iconic One M8. The UltraPixel camera of the M8 has been replaced by a much better 20 megapixel main camera, and the processor has been upgraded to an octa-core Snapdragon 810. The M9 isn't a great leap forward, but is one step closer to perfection. Click for more
|Sony Xperia Z5 Premium review|
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. Click for more
