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 cell phones in comprehensive mobile phone reviews.
To properly drill down to a list of our 10 favorites in the US, we based the updated 2015 rankings on a lot of geeked-out factors including hardware design, performance, battery life and camera quality.
Sure, your personal preference among iOS, Android and Windows Phone 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 get locked into a two-year contract or spring for an expensive unlocked, SIM-free smartphone, consult our best of guide, updated regularly.
10. Nexus 6
OS: Android 5 | Screen size: 5.96-inch | Resolution: 1440p | Memory: 3GB | Storage: 32GB/64GB | Battery: 3,220mAh | Rear camera: 13MP | Front camera: 2MP
The biggest smartphone on the list is the Nexus 6 from Google and Motorola. At a whopping 6 inches, it has room to compete with other flagships: a Snapdragon 805 processor, 3GB of RAM, all-day battery life, QuickCharge 2.0 and Android 5.1 Lollipop.
Nexus 6 has a nearly bezel-free display, so the finger-stretching dimensions actually manage to be not too far off the size of the iPhone 6 Plus, which includes Apple's physical home button. The size of the phone is comparable, yet the screen size is even bigger.
Of course, its bumped up cost isn't as budget-friendly at $650 - more than double the $300 starting price of the Nexus 5. Just make sure you can properly hold this two-handed phabet before entering into a two-year commitment or opting for the pricey no contract option.
