    Those aren’t contradictory. DP is via connection to GPU using the high speed lanes and the 2.0 USB is from the A16 chip, which was designed with USB2.0 over lightning in mind from my understanding.

      For people who don’t know, a “lane” in this case is a literal wire on the cable. You can have multiple lanes that have separate protocols, e.g. a lane for audio, a lane for DP, a lane for USB 3.

      IIRC there are always lanes for USB 2, and USB 3 speeds are achieved on separate lanes. Thats why all USB-C cables and devices must support USB 2.0.

      You said something I didn’t even think about: The a16 in the iPhone 15 is last year’s chip. Of course it doesn’t have usb 3.0 or anything else, just the 2.0 speeds it was designed for.

      I do wonder, however, if the A17 will retain the new updated usb feature that the A17 Pro has (clearly they’re binning something or other)
