The iPhone 15 series introduces USB-C, enabling compatibility with a wide range of accessories. The Lightning connector was somewhat more closed, as it was Apple's own standard. That changes with USB-C, which is more open to accessories.
With the iPhone 15 series, Apple iPhones have finally switched to USB-C, joining the ranks of most other Apple devices such as iPads and Macs. This means you can now use a single cable to charge all your Apple gadgets, making your life much easier. However, the speed of charging varies depending on whether you have an iPhone 15 Pro or non-Pro. iPhone 15 and iPhone 15 Max can charge up to 20W, while the Pro versions can squeeze in a slightly faster 27W. So still miles away from the speeds you see on certain Android phones, where 60W or more is normal.
Unlike Lightning, USB-C is not proprietary, so you can use a wide variety of USB-C cables or accessories on the market. In addition to just charging, there are actually quite a few other good options.

iPhone 15 can also share power, so you can use it to charge other devices, like your AirPods or even another iPhone. This is great when you're on the go and need to give your gadgets a quick boost.

Wired accessories USB-C also means you can connect wired accessories like keyboards, microphones and even wired headphones to your iPhone. This is great when you need a more reliable connection or want to save battery life.
USB-C hubs allow you to connect multiple devices to your iPhone at the same time. This is great when you need to connect to an external display, power source and USB accessories all at once.
