The iPhone 6s was released in September 2015 alongside the iPhone 6s Plus. The iPhone 6s came with an improved Apple A9 processor and double the Memory (RAM) as the previous model, the iPhone 6. The iPhone 6s also had a 12 Megapixel camera which is 35% better than the previous generation of iPhone camera, allowing it to take photos with twice the quality and record video in twice the quality aswell. The iPhone 6s came with an innovating improvement called 3D Touch. 3D Touch is implimented into the display on the iPhone 6s, and allows users to force touch on an application, which then gives them shortcuts to certain functions that the application has (such as, taking a selfie when 3D Touch is used on the camera application).
