USB Powershare wasting battery

[msalim98]

If I have USB powershare on on my Dell XPS 13 2015, does it waste my battery if I have nothing plugged in? In other words, if I put my computer to sleep, does the battery drain because the USB is always on, even if nothing is plugged in? Thanks for any response!

It shouldn't, or at least significantly under a milliamp.
