The iPhone 15 USB-C port delivers significantly more power to connected devices than its predecessor
iPhone 15 and iPhone 15 Pro can be charged from 0 to 100% in less than two hours using a USB-C cable and a standard Apple USB-C 20W charger. iPhone 15 can draw a maximum of 27W of electricity via the existing USB-C port. It remained practically unchanged compared to the iPhone 14 series, which charges at the same speed using the Lightning interface.
What’s different with the arrival of the USB-C port is that the iPhone 15 can now deliver significantly more power to connect accessories and external devices. According to Via Macotakar, the iPhone 15 will be able to deliver a maximum of 4.5 W to additional connected accessories and equipment connected via a USB-C connection.
Purely for the sake of comparison, the Lightning port on previous generations of iPhone devices delivered significantly less power, a maximum of 0.3 W.
This means that it is very likely that the range of different accessories for the iPhone will expand significantly, now that the devices can be supplied with sufficient power directly from the iPhone itself. Significantly easier and more convenient than using additional external rectifiers.
For example, USB-C portable drives that are powered directly from the device to which they are connected, can now also be directly connected to the iPhone and serve as external memory. On the iPhone 15 Pro models, a USB-C port with USB 3.2 Gen2 specifications is installed, which enables data transfer at speeds of 10 Gbps.
During the launch of the iPhone 15 model, Apple suggested that customers can now charge their AirPods or their Apple Watch on the go by plugging them directly into the iPhone 15 using a USB-C charging cable, reports 9to5Mac.
