Apple iPhone X (AT&T/T-Mobile/Global/A1901) 64, 256 GB Specs

Please note that this A1901 iPhone X model is compatible with FDD-LTE bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 29, 30, and 66 as well as TD-LTE bands 34, 38, 39, 40, and 41. It is intended for use with AT&T and T-Mobile in the United States (it does not support CDMA networks such as those used by Verizon and Sprint), but it does formally support carriers in Canada, the UK, the EU, and just about all other countries in the world with the major exceptions of Australia, New Zealand, China, Hong Kong, Japan, and India.

Regardless of carrier support, all iPhone X models have a 3D-touch capable 5.8″ (diagonal) OLED HDR “Super Retina” display (2436×1125, 458 ppi, 1 million:1 contrast ratio) that occupies nearly the entire front of the device with the bottom “chin” where the “Home” button once was gone entirely and replaced by a new facial recognition “Face ID” authentication system.

The iPhone X has three cameras. On the front — tucked in the rather awkward “notch” — is a new “TrueDepth” camera that in addition to supporting the “Face ID” functionality, takes 7 megapixel photos, shoots 1080p video, and has software support for Portrait mode, Portrait lighting, and more. The two rear cameras, one wide angle (f/1.8 aperture) and one telephoto (f/2.4 aperture), both have 12 megapixel sensors, support optical image stabilization, and shoot 4K photos and video. The cameras support motion tracking and offer augmented reality support, too.

The iPhone X uses a primarily “surgical-grade stainless steel” case 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 was sold in two color options, a dark “Space Gray” and silver.

Internally, the iPhone X is powered by a 64-bit “Apple A11 Bionic” processor with six cores — two performance cores and four high-efficiency cores — and has 3 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 X provides “up to” 60 hours of audio playback, 21 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.
