1. Samsung Galaxy S6 Edge

It's eye-wateringly expensive, but the Galaxy S6 Edge really is one of the most desirable phones on the planet right now. Its curved edges look stunning, and it's got plenty of power behind it, too, thanks to Samsung's octa-core Exynos 7420 chip. Its 2,560x1,440 Super AMOLED display is equally stunning, producing rich, vibrant colours and ultra-deep blacks. Its 16-megapixel camera is also fantastic. If you want a smartphone that will truly wow your friends and family, the Galaxy S6 Edge is the phone to buy.

2. Apple iPhone 6

It took Apple a while, but it finally increased screen size with the iPhone 6 range. Now with a 4.7in display, a fast processor, improved battery life and iOS 8.1, the iPhone 6 is an improvement in every way on the iPhone 5S. We also think that it strikes the perfect balance between screen size and physical size, making it the best iPhone for most people.

3. Motorola Moto G (3rd Gen, 2015)

The 2nd Gen Moto G was an exceptional smartphone, but the latest version of Motorola's monumental handset is even better. While it's not quite as good value as its predecessor, the 3rd Gen Moto G is by far one of the most comfortable and attractive budget smartphones around. Its large 5in HD screen looks great, it has a fantastic 13-megapixel camera, and its battery life is best in class. It also comes with 4G support and a microSD card slot, making it even more versatile than ever.  

Price when reviewed: £159 SIM-free. For the latest prices, see our full Moto G 3rd Gen 2015 review
Processor: Quad-core 1.4GHz Qualcomm Snapdragon 410, Screen Size: 5in, Screen resolution: 1,280x720, Rear camera: 13 megapixels, Storage: 8GB / 16GB, Wireless data: 3G, 4G, Size: 142x72x6.1mm, Weight: 155g, Operating system: Android 5.1.1

Best of the rest...

4. LG G4

When every other top end smartphone is made of metal, the G4's leather rear really helps it stand out from the crowd. It's also the first smartphone to have a colour spectrum sensor built into its rear camera, allowing it to produce more realistic images. It's not as fast as the S6, but its IPS Quantum display superb, and its battery life is pretty decent too. It's also one of the cheapest flagship phones available today, making it a great choice for those who don't want to shell out for the S6 Edge or iPhone 6.

Price when reviewed: £530 SIM free. For the latest prices, see our full LG G4 review Processor: Hexa-core 1.8GHz Qualcomm Snapdragon 808 Screen Size: 5.5in, Screen resolution: 2,560x1,440, Rear camera: 16-megapixel, Storage: 32GB, Wireless data: 3G, 4G, Size: 149x75x8.9mm, Weight: 155g, Operating system: Android 5.1

5. Apple iPhone 6 Plus

When Apple decided to do big, it went really big, with this huge 5.5in handset. Provided the size doesn't put you off, the high-quality screen, long battery life, brilliant OS and excellent camera make this the best (and most expensive) iPhone that you can buy.

Price when reviewed: £619 SIM-free. For the latest prices, see our full iPhone 6 Plus review
Processor: Dual-core 1.4GHz Apple A8, Screen Size: 5.5in, Screen resolution: 1,920x1,080, Rear camera: 8 megapixels, Storage: 16GB / 64GB / 128GB, Wireless data: 3G, 4G, Size: 158x78x7.1mm, Weight: 172g, Operating system: iOS 8

6. Sony Xperia Z3 Compact

Phones have generally become larger, but with the Sony Xperia Z3 Compact you get a high-end phone in a smaller package. It has the same top-end Qualcomm Snapdragon 801 CPU as its big brother, and is incredibly quick. Its 4.7in, 720p display is excellent and the 20.7-megapixel camera one of the best. If you want a smaller phone, this is the one to buy.

Price when reviewed: £348 SIM free. For the latest prices, see our full Sony Xperia Z3 Compact review
Processor: Quad-core 2.5GHz Qualcomm Snapdragon 801, Screen Size: 4.6in, Screen resolution: 1,280x720, Rear camera: 20.7-megapixel,Storage: 16GB, Wireless data: 3G, 4G, Size: 127x65x8.6mm, Weight: 129g, Operating system: Android 4.4.4

7. Vodafone Smart Ultra 6

The super-sized Vodafone Smart Ultra 6 is something of a budget miracle. Better value than the Moto G, this £125 handset has a 5.5in Full HD display, 13-megapixel camera and a super-fast Snapdragon 615 processor. It's tied to Vodafone, of course, but you won't find a better value smartphone for less.

Price when reviewed: £125 PAYG.

8. Samsung Galaxy Note 4

Samsung started the phablet market with its original Note and the Note 4 is the best model yet. A huge screen with a high resolution, plenty of power, tons of battery life and a stylus all combine to make this one of the best phablets you can buy.

Price when reviewed: £600 SIM free. For the latest prices, see our full Samsung Galaxy Note 4 review
Processor: Quad-core 2.7GHz Qualcomm Snapdragon 805, Screen Size: 5.7in, Screen resolution: 2,560x1,440, Rear camera: 16-megapixel, Storage: 32GB, Wireless data: 3G, 4G, Size: 153x78x8.5mm, Weight: 176g, Operating system: Android 4.4.4

9. Motorola Moto E (2nd Gen, 2015)

If you're looking for extremely low-cost Android phone that you can buy outright, the 2015 edition of the Motorola Moto E should be top of your list. Available for just £109, it's extremely good value. Its 960x540 screen is a little low-res, but its quality is very good. Performance is also respectable, and its battery life of 13h 30m in our video playback test is also extremely good for a budget handset. It even runs the latest version of Android, Lollipop.

10. Nokia Lumia 930

The Lumia 930 is one of Nokia's first handsets to come with Microsoft's latest Windows Phone 8.1 operating system, and what a difference it makes. Nokia's also pulled out all the stops to make sure the Lumia 930 is one of the most powerful and well-equipped Windows phones ever made. With a quad-core 2.2GHz Snapdragon 800 processor, a 20-megapixel camera, a large 5in Full HD AMOLED display and a huge 32GB of storage, there's hardly anything left wanting.

11. Microsoft Lumia 640

The Microsoft Lumia 640 is the perfect Windows phone if you don't want to fork out for the Lumia 930: it's much cheaper than Nokia's flagship handset, but it still comes with the latest version of Windows Phone 8.1 operating system (which is due to be upgraded for free to Windows 10 Mobile later this year) and the same funky colours. It also has a great 720p screen and excellent battery life, making this phone a great choice for anyone on a tight budget.
