The iPhone 6s introduces a significant shift in tactile interaction with 3D Touch, a pressure-sensitive technology that recognizes the force of a press to enable "Peek and Pop" shortcuts. In our hands-on testing, this hardware-software integration provides a more efficient way to navigate iOS by surfacing contextual menus without fully opening applications.
On the imaging front, the device is equipped with a new 12MP iSight camera. This sensor upgrade allows for high-fidelity photography and, for the first time on an iPhone, the ability to record 4K video (3840 x 2160) at 30 fps. When filming in 4K, users should be mindful of the increased storage requirements—approximately 375MB per minute of footage—compared to standard 1080p video.
According to official Apple specifications, pre-orders for the iPhone 6s and 6s Plus begin on September 12, 2015.
