iPhone X - Refurbished

The iPhone X features a 5.8-inch Super Retina HD OLED display that covers both DCI-P3 and sRGB color spaces and supports high dynamic range (HDR) imaging. It also includes the True Tone technology found on the iPad Pro and other iPhone devices, and has a typical peak brightness of 625 cd/m².

The Face ID unlock system completely replaces Touch ID on this model. An infrared camera reads a pattern of dots emitted from an invisible 30,000-dot projector onto the user’s face, creating a unique facial map, capturing an image of the face, and sending the data to the A11 Bionic chip’s secure element (which contains a dedicated AI neural engine) to match the user’s face with the one stored in the secure element. The infrared illuminator helps identify the user’s face in the dark. The dot projector places more than 30,000 invisible dots on the face to create a unique facial map. The system will not work with your eyes closed or when you are not looking at the phone, preventing access if you are not actively looking at the device’s screen.

The iPhone X has two 12MP rear cameras. The first is a wide-angle lens with a six-element lens, autofocus, infrared filter, burst mode, ƒ/1.8 aperture, and optical and digital image stabilization. It can record 4K video at 24, 30, or 60 FPS; or 1080p at 30 or 60 FPS; slow motion video (1080p at 120 or 240 FPS), and time-lapse camera with stabilization. It can capture panoramic photos, as well as recognize faces included in the photo. The second camera acts as a telephoto lens and has a ×2 optical zoom —digitally reaching a ×10 zoom—, ƒ/2.4 aperture, and optical image stabilization. It also has a quad-LED flash called True Tone.

On the other hand, the 7 Mpx front camera called TrueDepth with ƒ/2.2 aperture. It can capture in burst mode, has exposure control, face detection, auto-HDR, automatic image stabilization, Retina flash, records video at 1080p, and allows portrait mode, portrait lighting (beta) and Animoji function.
iPhone X features Apple’s A11 Bionic system-on-chip, a six-core processor manufactured using a 10nm lithographic process. It includes a Neural Engine, an accelerator for artificial intelligence calculations, mostly inferences for recognizing a user’s face and gestures, and an integrated M11 motion coprocessor.
