The iPhone 6s Plus was released in September 2015 alongside the iPhone 6s. The iPhone 6s Plus came with an improved Apple A9 processor and double the Memory (RAM) as the previous model, the iPhone 6 Plus. The iPhone 6s Plus also had a 12 Megapixel camera which is 35% better than the previous generation of iPhone camera. This allows it to take photos at twice the quality of the older iPhone 6 Plus. The iPhone 6s Plus came with an innovating improvement called 3D Touch. 3D Touch is implimented into the display on the iPhone 6s Plus, 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).
