The iphone 6s plus keeps the same desine as last years model like iphone 5s, 6s. the rounded rectangular shape, the curved edge, the antenna lines, the button, the ports, thecammera ring. same. same.the way a lot of it has been put togethar thouth, has changed.
the iphone 6s plus uses 7000 series aluminum for its casing.like the apple watch sport, the company is using their own custom composition, but its a similer to whats used in the aerospace industry.it alloyed with zinc, it creates the highest tensile strength possible
I really like this phone.
