Performance
Under the hood, the OnePlus One was powered by Qualcomm's Snapdragon 801 chipset, coupled with a quad-core 2.5 GHz Krait 400 CPU and an Adreno 330 GPU. Initially shipped with Android 4.4.2 KitKat and capable of being upgraded to Android 6.0.1 Marshmallow, it provided a fluid user experience sharply aligned with flagship performance levels at a fraction of the cost. The phone was available in configurations of 16GB or 64GB of internal storage, both paired with 3GB of RAM, offering users ample performance for multitasking and storage-heavy applications.
