iPhone
8 and 8 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.
