The iPhone 7 and iPhone 7 Plus are smartphones designed, developed, and marketed by Apple Inc. They were announced on September 7, 2016, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, and released on September 16, 2016, succeeding the iPhone 6S and iPhone 6S Plus as the current flagship devices in the iPhone series. The iPhone 7 features a new quad-core system-on-chip with improved system and graphics performance; an updated display screen; water resistance; stereo speakers; upgraded cameras, and a new dual-camera system on the 7 Plus model. The 3.5mm headphone jack was removed, but Apple included an adapter, along with earphones that connect to the Lightning port as an alternative.
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.
A Lightning-to-3.5mm adapter is sold by Apple as an accessory as well as being included with the iPhone 7 and 7 Plus. Apple also unveiled several Bluetooth-powered headphones, including Apple AirPods and three new Beats headphones. All four products utilize an in-house wireless chip known as Apple W1, which is designed to provide low-power Bluetooth operation and integration with iOS and macOS products (though they are still compatible with other Bluetooth-supported devices).
Apple has deliberately withheld pre-order sales numbers, citing that these are “no longer a representative metric for our investors and customers”. U.S. carrier T-Mobile announced that the iPhone 7 broke the record for first-day pre-order sales of any smartphone in its history. Although it did not release specific numbers, it also revealed that the weekend following the iPhone 7 announcement, the pre-order numbers for the iPhone 7 was its biggest iPhone launch ever, being “up nearly 4x compared to the next most popular iPhone”. On September 15, 2016, one day before the iPhone 7 went on sale, Apple announced that due to high demand, they have sold out of all Jet Black iPhone 7’s, and all colors of the iPhone 7 Plus, and that those models won’t be available in Apple Stores for walk-in customers on launch day. This may be because Apple opened up more reserve slots for customers in the iPhone Upgrade Program after those customers complained about the system used to reserve the phones had the slots filled up quickly after pre-orders opened, and customers couldn’t get the phone they wanted. These issues also caused a class action lawsuit to be filed against Apple because of the way they handled the system.
