The USB 2.0 information connectivity commonplace was launched in April of 2000, with a knowledge switch price of 480Mbps. Lightning, the connector commonplace used from the iPhone 5 to the iPhone 14, and the USB-C connector on the iPhone 15 and iPhone 15 Plus, use USB 2.0 signaling protocols and information switch charges.
The USB 3.1 information connectivity commonplace was launched in July 2013, and the USB Sort-C connector was finalized by the USB Implementers Discussion board (USB-IF) in August 2014. USB 3.2 was launched in September 2017, changing, absorbing, and renaming the USB 3.1 specification.

Merchandise labeled underneath both specification ought to work on the iPhone 15 Professional and iPhone Professional Max at native speeds, particularly if they’re USB-IF licensed.
Thunderbolt is a proprietary know-how owned by Intel and co-developed with Apple. It’s a {hardware} interface for connecting exterior peripherals to a pc (a PC or a Mac).

USB Energy Supply (USB PD) is a quick charging commonplace delivered over USB-C cables, supporting as much as 100W with Customary Energy (SPR) and as much as 240W with Prolonged Energy (EPR) supplied the cable and system help it. With USB PD, The cable “listens” to the system’s wattage wants and adjusts its power circulate accordingly. So, in the event you join an 18W iPhone 15 to a cable that may help as much as 240W, the charger brick and cable with USB PD help will throttle all the way down to 18W most cost price.
