This device is sold in most regions worldwide, except for the United States, Canada, Japan, and mainland China (as well as Hong Kong and Macao). It is, however, technically functional with carriers across the globe.
All iPhone 12 models have a 6.1-inch (diagonal) haptic-touch capable "Super Retina XDR" display (2532x1170, 460 ppi) that occupies nearly the entire front of the device. It has three cameras. The front-facing "TrueDepth" camera, housed in the "notch," supports "Advanced Face ID," captures 12-megapixel photos, and records 4K video, with software features like Portrait mode. The rear features a dual-camera system with 12-megapixel, 4K-capable Ultra Wide (f/2.4 aperture, 120-degree field of view) and Wide (f/1.6 aperture) cameras. Apple notes that the iPhone 12's "computational photography" features enhance low-light performance and reduce noise compared to earlier models.
The iPhone 12 uses an "aerospace-grade" aluminum case with flat sides and has glass on both the front and back. The front is protected by a "Ceramic Shield" cover for improved durability, while the back includes an integrated "MagSafe" magnetic charging connection. It is rated IP68 for splash, water, and dust resistance (maximum depth of 6 meters for up to 30 minutes). Initially offered in five colors—white, black, blue, (pale) green, and (PRODUCT) RED—a sixth color, purple, was added on April 20, 2021.
Internally, the iPhone 12 is powered by a 64-bit 3.0 GHz "Apple A14 Bionic" processor with six cores (two performance, four high-efficiency) and a 16-core Neural Engine. It has 4 GB of RAM and 64 GB, 128 GB, or 256 GB of flash storage. It also supports 802.11ax Wi-Fi 6 with 2x2 MIMO, 5G wireless, Bluetooth 5.0, Ultra Wideband for "spatial awareness," NFC for Apple Pay, "Express Cards with power reserve," and dual SIMs (one hardware nano SIM and one software-based eSIM).
Apple's battery life estimates for the iPhone 12 are "up to" 65 hours of audio playback, 11 hours of video playback, and 17 hours of streamed video playback.
