During its keynote today in San Francisco, Apple took the wraps off its marquee iPhone 6Shandset as well as the larger 5.5-inch iPhone 6S Plus.

As a successor to the6 Plus, the 6S Plus is equipped with 3D Touch, an A9 chip processor and a 12-megapixel camera that can shoot ultra-high-def 4K video. However, its camera still retains optical image stabilization and it has a larger battery to accommodate the bigger display, both of which differentiate it from its smaller 4.7-inch counterpart.
