iPhone 6S vs OnePlus 2

The OnePlus 2 has been heavily billed as a 'flagship killer' and there's no bigger flagship than the iPhone 6S. Apple's latest superphone is set to take the world by storm and with a stylish metal build, smooth performance, a promising camera and impressive features, such as 3D Touch and Touch ID, it's no wonder.The OnePlus 2 is no slouch either though, with powerful innards, a big screen, a fingerprint scanner and a comparatively low price. But is it really good enough to 'kill' the iPhone 6S?D
