The OnePlus One sports the most powerful bin of Qualcomm's quad-core Snapdragon 801 (MSM8974-AC), clocked at 2.5GHz, 3GB of LPDDR3 RAM, and a 3100 mAh cell. Connectivity options include 4G LTE, 2.4G/5G Wi-Fi, and Bluetooth 4.0. Wrapped within a magnesium chassis, the One is a relatively compact 5.5-incher, measuring 152.9 x 75.9 x 8.9 mm, and weighing just 162 grams. The 1080x1920 pixel resolution screen is literally slapped on top of the chassis, so the top and bottom bezels are actually recessed. At the back we have a 13-megapixel Sony IMX214 sensor with 6 lenses and a wide, f/2.0 aperture. Lastly, the OnePlus One is powered by a customized version of CyanogenMod OS, which has been redesigned with a minimal, completely flat UI.
