iPhone 8 and 8 Plus

iPhone 8 and iPhone 8 Plus are smartphones designed, developed, and marketed by Apple Inc. They were announced on September 12, 2017, alongside the higher-end iPhone X, at the Steve Jobs Theater in the Apple Park campus, and were released on September 22, 2017, succeeding iPhone 7 and iPhone 7 Plus.
Besides the addition of a glass back, the designs of iPhone 8 and 8 Plus are largely similar to that of their predecessors. Notable changes include the addition of wireless charging, a faster processor, and improved cameras and displays. The iPhone 8 and 8 Plus share most of their internal hardware with the iPhone X.
Reception of the phones was mixed, with reviewers praising the addition of wireless charging and the new Apple A11 processor, while significantly criticizing the aging design.

Hardware

iPhone 8 and 8 Plus retain the Retina HD Display found in iPhone 7, but they now feature True Tone technology, allowing for automatic screen adjustments based on surrounding ambient lighting. They can play HDR10 and Dolby Vision content despite not having an HDR-ready display, done by down-converting the HDR content to fit the display while still having some enhancements to dynamic range, contrast, and wide color gamut compared to standard content. 

 CAMERA

iPhone 8 features a 12 MP camera with autofocus, f/1.8 aperture and optical image stabilization capable of capturing 4K video at 24, 30, or 60 frames per second, or 1080p video at 30, 60, 120 or 240 frames per second.^[12] iPhone 8 Plus upgrades the main camera for a wide-angle lens with up to 10x digital zoom or 2x optical zoom, and retains a second, telephoto lens similar to the one found on iPhone 7 Plus, but with improved depth-of-field and lighting effects in Portrait mode.^[14] Both models have a 7 MP front camera with an f/2.2 aperture capable of capturing 1080p video at 30 frames per second and 720p video at 240 frames per second, along with face detection and high-dynamic range.

                                                    Processor

iPhone 8 and 8 Plus contain the Apple A11 Bionic system-on-chip, a hex-core processor that the company says features two cores that are 25% faster than the previous generation's A10 processor and four cores that are 70% faster than the prior model. The phones also feature an Apple-designed graphics processing unit 30% faster than prior units, with the same level of performance as the A10 at half the power. Both models come with 64 and 256 gigabyte storage options, and are offered in silver, gold or space grey color options. 

 

The phones have glass backs instead of the complete aluminum housing found on prior models, enabling the use of Qi-standard wireless charging. The phones are rated IP67 for water resistance.

The iPhone 8 and 8 Plus were also criticized for their durability, as drop tests performed showed that the rear glass is not "the most durable glass ever in a smartphone", as claimed by Apple. 

Camera testing company DxOMark gave the camera on iPhone 8 a rating of 92 and 8 plus a rating of 94, giving them the title of best smartphone cameras tested by the company.
