I’ve found that all my USB cables have a pronounced curve near the end, where I’ve left my phone/etc on the edge of a table to charge, with the cord hanging down.
This curve is just pronounced enough to be noticeable when I pick it up, so I get it the right way round at least 90% of the time.
I don’t have any USB-C devices yet, so I’m happily only using micro USB for everything.
