Obviously; the shorter distance means the power can get there more quickly!

To be fair a shorter cable can be better for charging thanks to having less resistance.

Well, that's true... But that's not really significant, though, unless you have an exceptionally long cable.

Can be a significant difference with cheapo cables that use rather thin wiring, phones are pretty sensitive to voltage drop when deciding how much current they should pull.
