12.9-inch iPad Pro (2nd Gen) devices feature a fully-laminated, antireflective 12.9-inch LED-backlit 2732x2048 (264 ppi, DCI-P3 color gamut) touch-sensitive "Retina" display. These models support a then new "ProMotion technology" that provides a 120 Hz refresh rate for smoother animations and lower latency when using the Apple Pencil accessory. The 12.9-inch iPad Pro (2nd Gen) models are powered by an Apple A10X processor. Other noteworthy features include dual cameras -- a rear-mounted 12 megapixel "iSight" camera capable of shooting stills and 4K video and a front-mounted 7 megapixel "FaceTime HD" camera capable of shooting stills and 1080p HD video, dual-band 802.11a/b/g/n/ac Wi-Fi with HT80 with MIMO capability and Bluetooth 4.2, as well as dual microphones and two sets of stereo speakers. Connectivity to computers, if desired, and power is provided by a Lightning port. A "Smart Connector" provides connectivity for a size-specific Apple Smart Keyboard. Additional input also is available courtesy of an optional "Apple Pencil" (A1603, MK0C2AM/A), which provides a variety of pressure sensitive sketching and drawing options. The battery life of this iPad Pro model is reportedly 10 hours "surfing the web on Wi-Fi, watching video, or listening to music."
