The Right USB-C CableThe problem with USB-C is that its capabilities are so vast, but not every USB-C cable supports every single function. The iPhone XS, iPhone XS Max, and iPhone XR are cut off from receiving the iOS 26 update, so they're especially ones to avoid. You can read more about what the port does here, but there are two important things to note: The iPhone 15, iPhone 15 Plus, iPhone 16, iPhone 16 Plus, iPhone 16e, iPhone 17, and iPhone Air support the USB 2.0 standard just like the iPhones before, so you'll max out at 480 megabits per second of data transfer speeds. The iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 Pro, iPhone 16 Pro Max, iPhone 17 Pro, and iPhone 17 Pro Max support the USB 3.0 standard and are capable of up to 10 gigabits per second of data transfer speeds. (Apple's iPhone 16, 16 Plus, and 16e have an easier-to-replace battery.)
