iPhone 7 and iPhone 7 Plus are smartphones designed by Apple Inc. The devices were announced on September 7, 2016. The iPhone 7 and iPhone 7 Plus jointly serve as successors to the iPhone 6S and iPhone 6S Plus.
The iPhone 7 features notable hardware upgrades over its predecessor, including a new quad-coresystem-on-chip with improved system and graphics performance, updated displays, water resistance, stereo speakers, upgraded cameras, and a new dual-camera system exclusive to the larger 7 Plus model. The 3.5 mm headphone jack was notably removed; the device ships with in-ear headphones that plug into the Lightning port, as well as a Lightning adapter for 3.5 mm headphones.
Specifications
The iPhone 7 is similar in design to the iPhone 6S, though with a "mirrored" finish, and is offered in a new darker "Jet Black" color option alongside the new black and the existing white, space gray, gold, and rose-gold colors. The "3D Touch" system from the 6S was retained, and the home button was updated to also feature force sensitivity. The iPhone 7 does not feature a 3.5-millimeter headphone jack; it was replaced by a second speaker for stereo sound. A headphone jack adapter which plugs into the Lightning port is included. The iPhone 7 features the Apple A10 Fusionsystem-on-chip, which consists of two low-power cores and two high-power cores. The A10 also features a hexa-core graphics chip capable of "console-level gaming". As with prior models, the iPhone 7 is avaliable in two sizes: one with a 4.7-inch screen, and a "iPhone 7 Plus" variant with a 5.5-inch screen. The displays have identical sizes and resolutions to the 6S (750p and 1080p), but with an increased color gamut and brightness.
