Apple iPhone 6S Plus has all the qualities and features of iPhone 6S. Because of the bigger size of the display and higher resolution, it is called 6S plus. In this smart gadget, Apple used a 5.5 inch Full HD retina display in iPhone 6S plus. As display consumes the most of the battery, the battery capacity is also higher than 6S. Additionally, both front and back camera has optical image stabilization that stabilizes the picture in case if the hand shakes a little in the last moment of a beautiful capture. Otherwise, everything else should be the same as 6S.
