The edge-to-edge top-to-bottom Super Retina display adopts OLED technology for true-to-life colors, deep blacks, and a million-to-one contrast ratio. It features a 2436 x 1125 resolution and 458 pixels per inch, the highest resolution and pixel density ever introduced in an iPhone. It supports HDR, wide color, 3D Touch, and True Tone for adjusting the white balance of the display to match the ambient lighting.
At 5.8 inches diagonally, the iPhone X has the largest display introduced in an iPhone yet, but with no bezels aside from a notch housing the camera and sensors, it fits comfortably in the hand. At 143.6mm tall by 70.9mm wide by 7.7mm deep, it’s not much bigger than an iPhone 8, and it’s smaller than an iPhone 8 Plus.
The glass body of the device is IP67 water and dust resistantand it enables support for inductive wireless charging for the first time. The iPhone X adopts the Qi wireless standard and can charge through the glass back using any Qi-certified charging accessory. Apple is making an “AirPower” accessory to charge iPhone X, Apple Watch Series 3, and AirPods simultaneously, but it won’t be out until later in 2018.
With an edge-to-edge design, there is no room for a Home button, so the iPhone X adopts a new user experience. A swipe up at the bottom of the screen brings up the Home screen, while a swipe and a hold brings up App Switcher. There’s a Tap to Wake feature for looking at notifications, the side button can be pressed and held to activate Siri, and the Control Center is accessed by swiping downwards from the top status bar.
