Apple iPhone 6s Plus Overview

As with the previous iPhone generation the Plus model comes with a larger 5.5-inch 1080p screen and optical image stabilization in the camera but is otherwise identical the the smaller 6s. The design remains unchanged compared to the 6 Plus but the new model is made out of stronger aluminum and glass that is claimed to be the most durable in the industry. There have been a number of improvements under the hood as well, including in the camera department.

Sensor resolution has been upped to 12MP and with the total number of pixels the number of phase detection sensors on the chip (the so-called 'focus-pixels) has been increased by 50% as well. Apple has applied various measures to keep image noise and other artifacts at bay with the smaller individual pixels. For example, deep trench isolation technology has been used to reduce cross-talk between photosites.

The camera is now also capable of recording 4K video and the FaceTime camera at the front comes with an increased 5MP resolution. Like we've seen on the LG G4 and some new Motorola devices it also uses the display as a light source in low light conditions. For this purpose the screen can light up three times brighter than normal and the color of the emitted light is matched to ambient light sources for natural skin tones and colors. Panorama mode has been improved as well. It can now capture even larger images up to 63MP and as before uses dynamic exposure for avoiding extreme jumps in brightness across the frame.
