Regardless of carrier support, all iPhone 8 models have a 4.7″ (diagonal) widescreen multitouch “True Tone” LED-backlit 1334×750 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 originally was offered in three metallic color options — gold, silver, or a dark “Space Gray”, but on April 9, 2018, Apple also added a (PRODUCT) RED Special Edition model to the lineup with a black front and a red back.
Internally, the iPhone 8 is powered by a 64-bit “Apple A11 Bionic” processor with sixcores — 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.
