10 best smartphones in the US

iPhone 6S joins our list of the best phones compared in 2015

OnePlus 2

9. OnePlus 2

The 'flagship killer' with a fantastic price sneaks into the top ten again

OS: Android 5.1 | Screen size: 5.5-inch | Resolution: 1920 x 1080 | RAM: 3GB/4GB | Storage: 16GB/64GB | Battery: 3,300mAh | Rear camera: 13MP | Front camera: 5MP

The OnePlus One was a brilliant phone in 2014, offering a great price for top end specs - it truly was a bargain phone.

The good news is the One Plus 2 has repeated that trick, upgrading the internals while (mostly) keeping the same low price. Its clever overlay still impresses and the little tweaks (such as audio improvement) work quite nicely.

We would have liked to see some upgrades on the screen front, or NFC for mobile payments, but on the whole the brand has managed to avoid stumbling over the 'tricky second album'.
