Is your favorite iPhone user due for an upgrade? They're in for a treat. This year's iPhone inherits the look of last year's model, but though it may look the same, everything has been upgraded.
The glass covering the iPhone 6S's 1334-x-750-resolution, 326ppi Retina HD display has been reengineered to be less susceptible to scratches, and the case redone using 7000 Series aluminum for enhanced durability. The third-generation 64-bit A9 chipset powers a system featuring double the memory, an M9 motion coprocessor, a faster Touch ID fingerprint scanner, a 4K video camera, a 12-megapixel rear camera and a 5-megapixel FaceTime camera for better selfies.
With a 5.5-in. screen, the iPhone 6S Plus features all of the same improvements as the 4.7-in. iPhone 6S, but does so in a device with a 1920-x-1080-resolution Retina HD display featuring 401ppi. The larger casing allows space for optical image and video stabilization hardware and for a larger battery.
In concert with iOS 9, the latest iPhones take photos to a new level with Live Photos, which captures a second of video before and after a photo is snapped, and 3D Touch, which triggers different actions depending on how hard you press on the screen.
This year, a new rose gold finish was added to the existing lineup of gold, silver and space gray with 16GB, 64GB or 128GB of onboard storage.
