You can do that with the iPhone 8 (and 8 Plus) and iPhone X (via Engadget). These are the first phones put out by Apple that will support a quicker charge rate if you have a higher capacity charger – though you’ll have to pick one of those up separately to take advantage. >Like the iPad Pro before it, the new iPhones actually support faster charging rates than their provided charging dongles can provide; using Apple’s 29-watt USB-C charger (the one which ships with the MacBook) and a USB-C to Lighting cable will help you top up your device much faster. You can also use a 61 or 87-watt charger, if you happen to have one of those from the purchase of a new 13 or 15-inch MacBook Pro.
