We use a special piece of software to check all functionality of the phone.
All iPhone XR models have a haptic touch-capable 6.1″ (diagonal) LCD “Liquid Retina HD” display (1792×828, 326 ppi, 1400:1 contrast ratio) that occupies nearly the entire front of the device. It has dual cameras. On the front — tucked in the “notch” — is a “TrueDepth” camera that in addition to supporting “Advanced Face ID” identification functionality, takes 7-megapixel photos, shoots 1080p video, and has software support for Portrait mode, Portrait Lighting, and more. The rear camera is a wide-angle (f/1.8 aperture) with a 12-megapixel sensor, supports optical image stabilization, and shoots 4K photos and video.
The iPhone XR uses an “aerospace-grade” 7000 series aluminum case and has a glass front and back. It is splash, water, and dust-resistant to the IP67 standard (maximum depth of 1 meter up to 30 minutes). It is sold in six color options — yellow, white, coral (salmon), black, (royal) blue, and (PRODUCT) RED.
Internally, the iPhone XR is powered by a 64-bit, 7 nm “Apple A12 Bionic” processor with six cores — two performance cores and four high-efficiency cores — and an “8-core Neural Engine.” It has 3 GB of RAM and, 128 GB, of flash storage. It also supports 802.11ac Wi-Fi with 2×2 MIMO, Bluetooth 5.0, LTE Advanced, NFC for Apple Pay, “Express Cards with power reserve” for compatible transit systems, and dual SIMs (one hardware nano-SIM and one software-based eSIM).
