Anyway, these issues could be user issues or bad luck (so please don’t comment on this), but I have one nitpick which isn’t:
USB 2.0 speeds for pro-res footage are a joke. Why even praise your camera and the pro resolution format being introduced on iphone, when I can’t get it off my PC via cable vat decent speeds? I only used it once to make for a side project, and had ~30min of footage. Took about 1.5h to copy.
Likewise, USB-C ports on a spec-compliant device do not indicate greater than USB 2.0 speeds (e.g. high speed), nor do cables with USB-C ports on both ends indicate greater than high speed.
In fact, there are plenty of devices with USB-C ports which do not support data channels at all (but these tend to have compatibility issues due to not being able to negotiate power delivery)
Don't get me wrong, USB-C is ideal for charging. However, it _always_ became extremely fickle with Android Auto. The connector would develop wiggle overtime, resulting in an unstable connection. You'd have to work voodoo to get it positions correctly - which would often result in even more strain and deterioration. My most recent phone became completely unusable with Android Auto after about 6 months.
3.2/3.1 aren't speeds, they are USB spec numbers. Those specs don't mandate the speeds you think they do.
It’s easier to let the phone upload them to iCloud and then download from there, but that shouldn’t be necessary (and requires a good internet connection).
I don’t think it’s a problem for normal people’s workflows, more if you’re trying to use them for professional video/camera things.
USB 3 will be a couple times faster than WiFi 6, used between modern apple devices, so I see how that would be beneficial, for people editing.
With Gigabit internet iCloud can be faster than USB 2.0
And they're a lot more awkward then using a cable.
They also might not even have a speed advantage over USB 2.0 if the router is in a different room.
