iPhone 7 is similar in design to iPhone 6 and iPhone 6S, though with a “mirrored” finish. Alongside the existing Silver, Gold, and Rose Gold colors, the device is offered in new Black and “Jet Black” colors. The “Jet Black” color is a darker shade with a high-gloss finish; it is created through a multi-step process, beginning with an anodization phase to make the surface of the casing a porous aluminum oxide, and then using a machine to “wipe” the casing through a powdered compound, absorbed by aluminum oxide. The process is concluded with an “ultra-fine particle bath” for additional finishing; the entire process takes less than an hour.
iPhone 7 no longer uses a physical home button, and instead it uses a touch-sensitive button with haptic feedback via the Apple Taptic Engine. The button is also pressure-sensitive. The “3D Touch” system from 6S was retained.
iPhone 7 does not feature a 3.5 mm headphone jack; it was replaced by a second speaker grille. A Lightning-to-3.5 mm connector adapter, as well as in-ear headphones that use a Lightning connector, are bundled with the device. Some headset brands has provided Lightning or wireless option before release, also headphones features noise-cancelling now can powered only by Lightning. The Lightning adapter is also sold independently. iPhone 7 is also water- and dust-resistant.
iPhone 7 uses the Apple A10 Fusion system-on-chip, which consists of two low-power cores and two high-power cores. The A10 chip also features a hexa-core graphics chip capable of “console-level gaming” As with prior models, iPhone 7 is available in two sizes: one with a 4.7-inch screen, and a “Plus” variant with a 5.5-inch screen. The displays have identical sizes and resolutions to 6 and 6S (at 720p and 1080p, respectively), but with an increased color gamut and brightness. Both device variants also contain a new iteration of Apple’s motion coprocessor, the M10. Unlike previous iPhone models, internal storage options for iPhone 7 begin at 32 GB instead of 16 GB. iPhone 7 Plus has 3 GB of RAM, more than any other iPhone to date,but the smaller, 4.7-inch iPhone 7 has only 2 GB.
iPhone 7 includes a 12-megapixel rear-facing camera with a quad-LED “True Tone” flash; its aperture was widened to f/1.8, and the standard-size phone model adds optical image stabilization — a feature that was previously exclusive to Plus models. iPhone 7 Plus includes a second 12-megapixel telephoto lens, which can be used to achieve 2x optical zoom, and up to 10x digital zoom. The front-facing camera on both versions was upgraded to a 7-megapixel sensor.
