If you haven't heard of the OnePlus One, you should put it on your smartphone shortlist. Available for just $299 unlocked, this device lasted a fantastic 13 hours and 16 minutes on our battery test. There are plenty of other reasons to scoop up the One, including the very flexible Cyanogen Mod software that runs on top of Android and generous 5.5-inch, full HD display. We also like the gritty texture on the back, so you're less likely to drop this long-distance runner.
