You will need to purchase a wireless charging pad or dock if you plan to take advantage of the new wireless charging feature found on the iPhone 8, iPhone 8 Plus or iPhone X. Apple plans to release its own charging mat called the AirPower, but it won't be available until next year. Until then Apple has suggested iPhone owners use third-party chargers from Belkin or Mophie, but any Qi-compliant device will work. You can see a list of Qi-supported devices on the wireless power consortium website.
The latest generation of iPhones are blazingly fast. The iPhone 8, iPhone 8 Plus and iPhone X all feature the A11 Bionic Fusion chip, which incorporates six processor cores, a Neural Engine, three-core GPU and M11 motion coprocessor. When it comes to speed, the A11 Bionic is 70 percent faster than the previous generation A10 chip, found on the iPhone 7 and iPhone 7 Plus. In fact, the A11 Bionic blows away the competition, too.
The iPhone X does not support the Apple Pencil. The Apple Pencil is only supported by Apple's "Pro" iPad models. This includes the 9.7-inch iPad Pro, 10.5-inch iPad Pro and both generations of the 12.9-inch iPad Pro.
There are plenty of third-party styluses that claim to work with all touch screen devices, including the iPhone. There are no Apple designed styluses for the iPhone X at this time.
