iPhone 15 and iPhone 15 Pro can charge from 0 to 100% in under two hours with a USB-C cable and Apple’s standard 20W USB-C charging brick. iPhone 15 can charge at a maximum of 27 watts over the USB-C port. However, that is unchanged from the iPhone 14 series which could charge at the same speed over Lightning.
What is different though with USB-C is that the iPhone can now output significantly more power to accessories. Via Macotakara, iPhone 15 will be able to output up to 4.5 watts to accessories via USB-C.
