The iPhone 6s / 6s Plus enclosure is made from the same grade of aluminium used in the aerospace industry. It’s created from a unique composition of elements that make it the strongest alloy we’ve ever used in an iPhone. The new glass on iPhone 6s / 6s Plus is made using a special dual ion‑exchange process, which makes it stronger at a molecular level and the most durable in the smartphone industry.
The smooth, continuous unibody design created for iPhone 6 / 6 Plus extends to iPhone 6s / 6s Plus. Its familiar form feels just right in your hand. And now there are four stunning ﬁnishes to choose from: gold, silver, space gray, and the new rose gold.
Touch ID lets you unlock your phone and make purchases with Apple Pay simply by using your ﬁngerprint. It uses highly sophisticated algorithms to recognize and securely match your ﬁngerprint. And the improved Touch ID sensor detects your ﬁngerprint even faster than the previous generation.
iPhone 6s / 6s Plus introduces a next-generation, Apple-designed image signal processor that works with iOS 9 to provide better temporal and spatial noise reduction as well as third-generation local tone mapping. A new 12MP sensor uses advanced pixel technology. Every pixel in the sensor has been reengineered to prevent crosstalk between the subpixels, meaning we could fit a lot more pixels in the sensor for a sharper photo that has less noise and truer color. And the 5MP FaceTime HD camera includes Retina Flash to achieve perfectly lit selﬁes. When you use Retina Flash, a custom display chip drives the display to flash three times brighter than usual. Combined with True Tone technology, Retina Flash provides the perfect lighting for whatever environment you’re shooting in.
