I bought my oneplus 10 pro for sub $500 during a sale, and it has usb3.1. It’s last year’s model. You can get a pixel 6 with usb3.1 for less than $400. A Galaxy S21 has usb3.2, less than $500.
That’s almost every major android brand for $500 or less with 3.1 or better. The cheapest you can buy an iPhone 15, the one with usb2.0, is $800. What are you on about?
