Update: All of the major phones have launched in the US, from Apple's iPhone 6S, to Google's Nexus 6P, to Samsung Galaxy Note 5. See our updated ranking of our best phones recommendations.
Knowing the best smartphone you can buy right now is more than just a hunch for us. We test out the latest and - sometimes - greatest phones in comprehensive mobile phone reviews.
To drill down to a list of our 10 favorites in the US for 2015, we based the updated rankings on a lot of geeked-out factors: design, performance, battery life and camera quality.
Sure, your personal preference among iOS 9, Android Marshmallow and Windows Mobile 10 could sway you to another device besides our top-ranked phone. Likewise, availability via AT&T, Verizon, Sprint and T-Mobile is an outlier. The best phone for AT&T may not be available on-contract on Verizon, and vice-versa.
But that's why we have more than just a No. 1 pick, which, spoiler alert, isn't Apple's iPhone 6 or iPhone 6 Plus. We're not that predictable. Before you lock into a binding contract or spring for an expensive unlocked, SIM-free smartphone, consult our best phone guide, updated regularly.
10. 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'.
