Apple is using a new display in the iPhone 7 that's 25 percent brighter than the display in the iPhone 6s, so it's going brighter and clearer outdoors, especially in full sunlight. The display is also using a cinema-standard wide color gamut and end-to-end color management, for more vivid, saturated colors.The resolution of the display is the same, at 1134 x 750 (326 ppi) for the iPhone 7 and 1920 x 1080 (401 ppi) for the iPhone 7 Plus, and the screen sizes continue to measure in at 4.7-inches for the iPhone 7 and 5.5-inches for the iPhone 7 Plus.
On the outside, the iPhone 7 and the iPhone 7 Plus look a lot like the iPhone 6s and the iPhone 6s Plus. The dimensions, aside from weight, are identical. The iPhone 7 measures in at 138.3mm tall, 67.1mm wide, and 7.1mm thick, while the iPhone 7 Plus is 158.2mm tall, 77.9mm wide, and 7.3mm thick.At 138 grams and 188 grams for the iPhone 7 and iPhone 7 Plus, respectively, the two devices are slightly lighter than previous-generation iPhones.
3D Touch continues to be an integral part of the display, built into one of the display layers. 3D Touch is expanded multi-touch feature that allows the iPhone to measure different levels of pressure in addition to taps, swipes, and pinches.3D Touch is used across iOS 9 and iOS 10 to enable shortcut gestures called a "Peek" and a "Pop" both at the home screen and in iOS apps. A light press enables a Peek, while a deeper press enables a Pop, and there are unique swipe gestures to open up menus and take actions when using Peeks.
The iPhone 7 and the iPhone 7 Plus feature a huge jump forward in camera technology, for photographs that are clearer, brighter, and crisper, even in low-light conditions.Optical image stabilization, once a feature limited to the 5.5-inch iPhone, is built into the iPhone 7, compensating for small movements and hand shakiness when snapping a photo to allow for longer exposure times (3x longer than iPhone 6s). There's a new 6-element f/1.8 aperture lens that lets 50 percent more light into the sensor while keeping photos sharp at the edges.
