The iPhone 8 includes a 4.7-inch display, while the iPhone 8 Plus features a larger 5.5-inch display. Both displays were upgraded with True Tone support, designed to adapt color temperature and intensity to the ambient light in a room for a more natural, paper-like viewing experience. 3D Touch and P3 wide color support for a greater range of colors continue to be available.

Apple chose glass for the body of the iPhone 8 and the iPhone 8 Plus to enable a Qi-based inductive wireless charging feature, which allows the two devices to be charged when placed atop any Qi-certified inductive charger.

Inside the iPhone 8 and iPhone 8 Plus, there's a six-core A11 Bionic chip, which Apple at launch said was the smartest, most powerful chip ever introduced in a smartphone. There are two performance cores that are 25 percent faster than the A10 Fusion chip in the iPhone 7, and four efficiency cores that are 70 percent faster.
