group of smartphone models produced by Apple Inc.

Claiming that “the only thing that changed is everything”, Apple unveiled the iPhone 6S and 6S Plus on September 9, 2015. Well, not everything. The 2015 models look just like the 2014 iPhones at first glance, although there is a new rose gold color.

The iPhone 6S is a half-ounce heavier than the iPhone 6 , although its dimensions are the same. Screen resolution remains 1334 x 750 pixels, but the screen is pressure sensitive like Apple Watch (Apple calls this 3D Touch). Finishes include gold, silver, space gray, and rose gold.

The 2015 iPhones are made of 7000 Series Aluminum, the same material used for the Apple Watch and a step ahead of the iPhone 6.
