The push for ease of use has brought about 3D touch - literally adding a sense of depth to your interaction with the smartphone. And the device's response comes from an all new Taptic engine for unrivaled feedback precision.
It is the former that accounts for the most dramatic changes the 6s Plus brings physically. The hair's breadth increase in dimensions you won't notice, but the added weight is immediately felt. And while the 4.7-inch iPhone 6s is still manageable despite the extra heft, the Plus is pushing the boundaries of portability.
Part of the growing up process is the new camera. Apple is finally catching up with the times and now offers 12MP stills, complete with 4K video recording - the iPhone is no longer the favorite target of mockery from supercharged Android flagships. Double the RAM and a new, more powerful A9 chip round up the list of changes that Apple delivered.
