Apple introduced the next-generation iPhone 6s and iPhone 6s Plus at its media event in San Francisco on September 9. The new iPhones feature an A9 chip and M9 motion coprocessor, 3D Touch, 12-megapixel rear-facing camera, 5-megapixel front-facing camera, stronger glass and Series 7000 aluminum, faster Touch ID, Live Photos and a new Rose Gold color option.
iPhone 6s and iPhone 6s Plus are powered by an Apple A9 chip and embedded M9 motion coprocessor that deliver up to 70% faster CPU performance and up to 90% faster graphics compared to the A8 chip inside the iPhone 6 and iPhone 6 Plus.

3D Touch on iPhone is similar to Force Touch on Apple Watch, enabling users to make "peek and pop" gestures on the screen to access actionable shortcuts or preview content, such as text messages, flight information, calendar appointments and more. There's also a new Taptic Engine inside of the iPhone 6s that enables haptic feedback so you get touch-based responses when using 3D Touch.
The smartphones feature an improved 12-megapixel rear-facing iSight camera with 4K video recording and 5-megapixel front-facing FaceTime camera with true tone Retina Flash -- in low light, the front display will flash for a split second instead of using a traditional LED flash.
iPhone 6s and iPhone 6s Plus also have a second-generation Touch ID fingerprint scanner that is up to two times faster compared to Touch ID on previous iPhones.

The iPhones are crafted from Series 7000 aluminum and come in a new Rose Gold color, alongside Silver, Space Gray and Gold. Otherwise, the handsets look virtually the same as the iPhone 6 and iPhone 6 Plus, but they are slightly thicker and heavier.
