    The battery life on my 2011 15" MBP is significantly shorter than my old 13" MBP 2009.

    If I do a Skype video conference I get <1hr. For normal computer uses I get what seems like 4-5hours. Is there a diagnostic I can run that will be useful If I take it in to the genius bar to show them?

    No problem with that, you might extend your battery a little bit by calibrating it

    I believe skype loads up the dedicated GPU which would shorten battery life by a lot. If you want to stop this download GFXCardStatus

    That sounds fairly normal for a macbook pro, personally my white iMac has a good battery it lasts aslong as the lights are on
