If the rumors of the iPhone 15 Pro gaining a USB-C port weren't enough, then pay attention to the latest rumor from leaker Analyst 941, who claims the next-gen pro iPhones will support Thunderbolt 3 connectivity.
Thunderbolt 3 is normally found on desktop and laptop computers, and can transfer data at up to 40 gigabits per second while also handling power and video at the same time. For comparison, Apple's Lightning connector, used on iPhones for the past decade, uses USB 2.0, a 20-year-old standard that has a 0.48 gigabits per second data speed cap, which is magnitudes slower.
