The OnePlus One made its debut on April 25, 2014, with a reputation that soon garnered a lot of disciples. Its relatively low cost belied its rather remarkable build, quality, and number of specs. Indeed, its manufacturer, a Chinese start-up called OnePlus, marketed the device as the “Flagship Killer,” in reference to the phone’s potential to take considerable market share from the leading (and way more expensive) smartphones of the era, like the iPhone and Samsung Galaxy S series. Also, it has achieved cult status due to its unique retail system; it is sold exclusively from the manufacturer website, and customers could only purchase it with an “invite.”

Using a slate form factor, the OnePlus One is large enough to be considered a phablet of sorts. Its 5.5-inch screen is fortified with Corning Gorilla Glass, and it yields a high-definition resolution of 1,080 by 1,920 pixels. The chassis itself is constructed from magnesium, with a curved textured black or white rear.

The OnePlus One runs on a CyanogenMod operating system that is based on the Android platform. Its chipset is the Qualcomm MSM8974AC Snapdragon 801, which comprises a quad-core 2.5GHz Krait 400 central processing unit and an Adreno 330 graphics processor.

For memory, the OnePlus One has 3GB RAM; as well as 16GB and 64GB flash memory configurations for storage of music, video, and images. The 16GB phone has the white finish, while the 64GB version has the black rear end.

The OnePlus One comes with two cameras. The primary camera is a 13-megapixel (MP) feature that includes geo-tagging, face detection, auto and touch focus, dual-LED flash, panorama view, and high-dynamic-range imaging. It also acts as a video recorder, producing video files at up to 2,160 pixels at 30 frames per second (fps). The secondary, 5 MP camera can also record video, albeit at 1,080 pixels at 30 fps.

The lithium-polymer battery on the OnePlus One, rated at 3,100 mAh, is non-removable. It has an endurance rating of 66h, with a talk time of 19 hours 56 minutes, web browsing time of 9 hours 46 minutes, and video playback time of 11 hours 23 minutes.

Since the OnePlus One is the first product from OnePlus, there are no new features associated with this phone.
