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.

Processor

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.
