My battery doesn't dropped charge when I shut my macbook ... otherwise
I would have noticed this.
I have think to a bug of the pm-utils because it happens only with the
hibernation.

In this moment I'am charging my battery ... this night I shut my Mac (
no hibernation ), and tomorrow
I'am sure at 100%. ( I repeat that I never noticed this, but .. ).
