The OnePlus 2 is available in two different configurations: a 16GB version with 3GB of RAM, and a 64GB version with 4GB of RAM. This new camera adds optical image stabilization (OIS) and a laser autofocus system, which could improve low-light performance and focus latency. However, the Sony IMX214 sensor used in the OnePlus One has been swapped for an Omnivision sensor in the OnePlus 2. When it comes to the camera, OnePlus sticks to a proven formula, pairing a 13 MP sensor with an f/2.0 aperture lens. It also only supports USB 2.0 speeds for data transfer. For charging, the OnePlus 2 includes a USB Type-C port, but lacks the fast charging capability seen in most other flagships. While the battery is not swappable, it is at least pretty easy to replace. The OnePlus 2 uses a 3300mAh battery, slightly larger than the Nexus 6's but smaller than the Nexus 6P's. The weight, at 175 grams, is slightly heavier than the Galaxy Note 5 but lighter than the Moto X Pure Edition. OnePlus keeps the size manageable with a case slightly larger than the HTC One M9 but smaller than the iPhone 6s Plus. It is slightly thicker, however, at 9.85mm versus the 8.9mm of the OnePlus One. Many phones grow in size with each iteration, but the OnePlus 2 is slightly smaller than the OnePlus One in both width and height. We'll see if this strategy is successful later in the review. OnePlus, however, is using the newer revision 810 v2.1 in its latest model, and hopes to tame the dragon by underclocking the higher performing Cortex-A57 cores to 1.77GHz. Because of this, some OEMs opted for the hexa-core Snapdragon 808, which generates less heat, while others like Samsung went with its in-house Exynos SoC. Qualcomm and its customers found themselves in hot water when it was revealed that the 810 suffers from overheating issues. Internally, the OnePlus 2 features the same Snapdragon 810 octa-core SoC with Adreno 430 GPU found in other current flagship devices, including the HTC One M9, Sony Xperia Z4, and Xiaomi Mi Note Pro.
