Question: is the iphone x fast charging?
Answer: The fastest way to charge up a new iPhone (iPhone 8, 8 Plus, X, XS, and XR) is to make use of the fast charge feature. However, to do this you will need a USB-C Power Delivery charger and a USB-C-to-Lightning cable. This setup will take your iPhone from flat to 50 percent charge in 30 minutes.
