Doing this once will fix the indicator if it does ever become inaccurate.

However, as the others above have mentioned this doesn't appear to be a battery issue, it's a firmware issue. I notice the same thing. So the full-empty-full-charge trick won't work here, it's a programming problem. Hopefully a patch fixes it up soon.
