Regardless of carrier support, all iPhone 8 models have a 4.7 (diagonal) widescreen multitouch True Tone LED-backlit 1334x750 native resolution Retina HD display (326 ppi, 625 cd/m2) and a taptic-engine powered solid state clickless Home button.
It has dual cameras -- a rear 12-megapixel 4K camera with optical image stabilization, a f/1.8 aperture, a 6-element lens and wide color capture -- as well as a front 7-megapixel FaceTime HD camera with support for 1080p video. The cameras support motion tracking and offer augmented reality support, too.
The iPhone 8 uses an aerospace-grade aluminum alloy case reinforced by steel and has a glass front and back. It is splash, water, and dust-resistant (IP67), but not water-proof, and it has stereo speakers and a Lightning port. It is offered in three metallic color options -- gold, silver, or a dark Space Gray.
Internally, the iPhone 8 is powered by a 64-bit Apple A11 Bionic processor with six cores -- two performance cores and four high-efficiency cores -- and has 2 GB of RAM, as well as 64 GB or 256 GB of flash storage. It also supports 802.11ac Wi-Fi with MIMO, Bluetooth 5.0, LTE (4G), and NFC for Apple Pay.
Apple estimates that the iPhone 8 provides up to 40 hours of audio playback, 14 hours of talk time, 12 hours of Internet use, and 13 hours of wireless video playback. Because of the device's glass back, the battery can be charged wirelessly using a charging mat that supports the Qi standard.
