USB-C on iPhone 15 series: What else can it do besides charging, data sync

One of the most notable changes in the iPhone 15 series is the USB-C connector. The baseline iPhone 15 models, the iPhone 15 and iPhone 15 Plus, have USB 2.0, and the Pro models get the USB 3.2. Ahead of the iPhone 15 series availability, Apple has released a document detailing capabilities that the universally accepted standard brings to iPhones.

According to a support document, all models in the iPhone 15 series will be able to charge Apple Watch, AirPods case, and other accessories that support power delivery through USB-C. The USB-C connectors on the iPhone 15 models can pass through power at up to 4.5W to charge connected devices. This is a huge improvement compared to 0.3W power output available on its proprietary Lightning port.
