Go long enough and even your minimal charge is exhausted

Then how can Macs be charged if they are fully exhausted?

I have no idea. Maybe they can't, but we won't find out for 5 years when someone brings one out of a closet. Maybe there is enough current leakage when in non charging mode for them to run that much electronics.
