The non pro phones don’t have the RAW photo and video that the pro phones do.
RAW takes up a massive amount more space per photo and video than normal compressed images.
Also, I don’t know anyone with an iPhone that doesn’t just automatically back their photos up to iCloud anyway, meaning that all of their non RAW photos and videos are constantly transferred throughout the day to iCloud. The only people I do know that transfer things over cable are the ones that actually use the ProRes and ProRAW photos and video.
