"Maximizing iPhone 15's Charging Speed and Connectivity with USB-C"
The iPhone 15 and iPhone 15 Pro now come with a USB-C port instead of Apple's Lightning port, allowing for faster charging. To fast charge the iPhone 15, you'll need a higher wattage charging brick, such as Apple's 20W USB-C power adapter, which can charge the phone from zero to 50% in about 30 minutes and to 100% in under 2 hours. Other higher-wattage USB-C charging options are also available on the market. USB-C allows for fast charging of all Apple devices using the same cable and a 60W (or higher) MacBook power adapter.
