1. Motorola Moto X Force

The Motorola Moto X Force is truly the king of all smartphones. With its incredible shatterproof display, you never need to worry about breaking your phone's screen ever again. We've hit it with a baseball bat, chucked it on the floor (concrete or otherwise) and it's come out completely unscathed.

It's an astonishing feat of engineering, and to make things even better, Motorola has also equipped it with a gorgeous 5.4in 2,560x1,440 AMOLED panel, a super fast octa-core processor, a fantastic camera and one of the largest batteries we've seen this year. Even if you've never dropped a smartphone in your life, you never know when that dreaded day might arrive. With the Moto X Force, you can just keep on rolling with the punches, making it our top smartphone of 2015.

2. 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.

3. 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.

Processor: Dual-core 1.4GHz Apple A8, Screen Size: 4.7in, Screen resolution: 1,334x750, Rear camera: 8 megapixels, Storage: 16GB / 64GB / 128GB, Wireless data: 3G, 4G, Size: 138x67x6.9mm, Weight: 129g, Operating system: iOS 8

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

Motorola Moto G 3rd Gen best budget smartphone

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

5. Nexus 5X

Nexus 5X

It's that time of year again, when we not only get a new Nexus phone but a whole new version of Android to go with it. This year, it's the Nexus 5X and Android 6.0 Marshmallow, making this the go-to phone for Android purists. After last year's disappointing Nexus 6, the 5X is a breath of fresh air. It may not be the most attractive phone you've ever seen, but its fast internals and excellent screen make it great value for money. It's also got one of the best cameras we've seen in recent months, too, making it a fantastic all-round package. 

The Nexus 5X isn't the only Nexus phone this year, though, as Google has also launched the super-sized Nexus 6P, which is made by Huawei. The 6P is equally good value for those after a big screen phablet, but for us, the Nexus 5X has the greater long-term appeal. It's cheaper, it's slightly easier to hold and it's generally a bit more practical. 

Price when reviewed: £339 SIM free. For the latest prices, see our full Nexus 5X review

Processor: Hexa-core 1.8GHz Qualcomm Snapdragon 808 Screen Size: 5.2in, Screen resolution: 1,920x1,080, Rear camera: 12.3 megapixels, Storage: 16GB / 32GB, Wireless data: 3G, 4G, Size: 147x73x7.9mm, Weight: 136g, Operating system: Android 6.0

6. Sony Xperia Z5

Sony Xperia Z5

The Xperia Z5 has the most colour accurate LCD display I've ever seen, delivering bright, punchy colours that outshine almost every other smartphone display I've tested. If that wasn't enough, it's one of the fastest Android phones around, too, with blistering web browsing speeds and exceptional gaming performance. Topping it all off is Sony's brand-new chassis, which has a gorgeous frosted glass finish that dramatically improves the phone's grip and comfort, and a handy fingerprint sensor built straight into the power button, making it easier than ever before to keep your phone secure. 

Price when reviewed: £549 SIM free. For the latest prices, see our full Sony Xperia Z5 review

Processor: Octa-core Qualcomm Snapdragon 810 Screen Size: 5.2in, Screen resolution: 1,920x1,080, Rear camera: 23 megapixels, Storage: 32GB, Wireless data: 3G, 4G, Size: 146x72x7.3mm, Weight: 154g, Operating system: Android 5.1.1

7. Sony Xperia Z5 Compact

Sony Xperia Z5 Compact display

If the Z5 is just a little bit too big for your pocket, the Z5 Compact is the phone for you. While its screen only has a 720p resolution rather than Full HD, the Z5 Compact is just as fast as its big brother and has exactly the same camera sensor, making it excellent value for a miniature flagship smartphone. It's also got a fantastic display and a beautiful design, borrowing the same frosted glass finish as the Z5. 

Price when reviewed: £429 SIM free. For the latest prices, see our full Sony Xperia Z5 Compact review

Processor: Octa-core Qualcomm Snapdragon 810 Screen Size: 4.6in, Screen resolution: 1,280x720, Rear camera: 23 megapixels, Storage: 32GB, Wireless data: 3G, 4G, Size: 127x65x8.9mm, Weight: 138g, Operating system: Android 5.1.1

8. Motorola Moto X Play

The Moto X Play may not be Motorola's flagship smartphone any more, but this mid-range monster is extremely good value. With a battery life to rival the Samsung Galaxy S6, this smartphone has more than enough stamina to keep you going all day, and its octa-core processor Snapdragon 615 has plenty of speed, too. Its 21-megapixel camera is also excellent, providing plenty of detail with bright, rich colours. 

Price when reviewed: £270 SIM free. For the latest prices, see our full Motorola Moto X Play review

Processor: Octa-core Qualcomm Snapdragon 615, Screen Size: 5.5in, Screen resolution: 1,920x1,080 Rear camera: 21 megapixels, Storage: 16GB /32GB, Wireless data: 3G, 4G, Size: 148x75x8.9mm, Weight: 169g, Operating system: Android 5.1.1

9. Vodafone Smart Ultra 6

Vodafone Smart ultra 6 front

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. For the latest prices, see our full Vodafone Smart Ultra 6 review 

Processor: Octa-core Qualcomm Snapdragon 615, Screen Size: 5.5in, Screen resolution: 1,920x1,080 Rear camera: 13 megapixels, Storage: 16GB, Wireless data: 3G, 4G, Size: 154x77x8.4mm, Weight: 159g, Operating system: Android 5.0.2

10. 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 megapixels, Storage: 32GB, Wireless data: 3G, 4G, Size: 153x78x8.5mm, Weight: 176g, Operating system: Android 4.4.4

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

Moto E 2015 press shot

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.

Price when reviewed: £109 SIM-free. For the latest prices, see our full Motorola Moto E (2015) review

Processor: Quad-core 1.2GHz Qualcomm Snapdragon 410,Screen Size: 4.5in, Screen resolution: 960x540, Rear camera: 5 megapixels, Storage: 8GB, Wireless data: 3G, 4G,Size: 130x67x12.3mm, Weight: 145g, Operating system: Android 5.0.2

12. Vodafone Smart Speed 6

Vodafone Smart Speed 6

Motorola's budget phones are excellent, but for those that don't want to pay £90 for the 2nd Gen Moto E (listed below), the £50 Vodafone Smart Speed 6 is a truly excellent alternative. You'll need to join Vodafone to get one, as it's only available on Pay as You Go, but if that doesn't bother you, then this compact smartphone is easily the best in its price range. It's just as fast as the Moto E, has great battery life, and runs stock Android, too, making it very simple and easy to use.

Processor: Quad-core 1.0GHz MediaTek MT6735M Screen Size: 4.5in, Screen resolution: 854x480, Rear camera: 5 megapixels, Storage: 8GB, Wireless data: 3G, 4G, Size: 132x65x9.9mm, Weight: 146g, Operating system: Android 5.1
