Going by the history of Apple’s releases, after the iPhone 6, a 6S model is logically up next. Also, the upcoming iPhone will be a game changer in terms of specs and features, according to Ming-Chi Kuo, analyst at KGI Securities. The latest ‘S’ model of the iPhone, might have a similar chassis to the iPhone 6 and will boost similar colors. However, a latest variety of sapphire glass could change the way the Apple flagship could weigh. As for the screen size, expect no more than 4.7 inches and a slim form factor at just 5.5 inches. We are anticipating Apple System on Chip A9, from the Samsung stable on the beauty besides expecting specs such as Force Touch and Corning Project Phire. Though not certain about what could finally make it to the Apple iPhone 6S, we are geared up for a huge leap in terms of technical offerings.
