    Nickholl, sure sorry about the name calling. it would be hard to absorb 180 pages. I am new to forums and their rules. I myself was rudely smacked down in my very first post. it's too bad some folks can't keep it friendly with newcomers. I'll get slapped for this post, but who gives a s$&(. hope you find a solution. you've probably already been there, but the folks over at macrumors forum are more friendly.

    davidfromcarrabelle, You learn to ignore the patronizing person(s) on the forums, they preach forum protocol and etiquette but end up being 'Apple bible thumping fanatics'. In short they 'ain't' the forum monitors, just people who spend way too much time on these forums. (which isn't always bad when they are being HELPFUL, and not busy patrolling!)

     

    You're welcome here as are your posts and questions.

    So aside from a fresh install/SMC reset (not a good option for me) Is there any other options or is this hang time until the patch?

     

    I read something about SMC 1.7 firmware update . I read the write up on it at http://support.apple.com/kb/DL853 and it doesn't seem to be about battery life improvement.

    How do I see what version I'm on, the paper also says there's a firmare app which I do not have /Applications/Utilities/MacBook Pro EFI Firmware Update.app

    For OS compatibility you should always be running the lastest firmware (EFI Boot and SMC) updates.  You can check your Hardware Overview or download and try installing them.  If either are already up to date the installer will end with that message.

     

    If you're experiencing poor battery performance and you don't want to try a fresh install (and you've already updated any firmware), waiting for the next update is about your only choice.

     

    FWIW, I for one really appreciate those that "spend too much time here" in an effort to help others...I've really benefited from their advice. 

     

    EDIT: Ahh...beat me to it.

    richsadams, Thank you. Ye, my updates are up to date. Guess I'm in the wait time mode. 

     

    (There are some amazing people on here who are extremely knowledgable who's information I myself have relied upon. I like the modest genius vs. the arrogant however.)

     

    You yourself have been very helpful and I thank you !

    After a complete charge the battery indicated I had 9h.20min!!!!!!!! Now with 72% left I have 5h.49min. I think it drops a lot quicker than Lion, but it's a lot better than the first installation. I'll keep checking it!

    no worries dude. I've been a loyal Apple user for 15 years now, and have never had a bad word to say. Im sure they'll rectify the problem eventually (even if it involves replacing my machine) My issue was that I think they DID know about the software issue  in the store but were just trying to stall me. TBH I wish they'd have just said it to start with - but instead they got me in again the next day to replace the battery which the day before they had given the ok - and then only mentioned the possibility of it being a softtware issue at the last minute.   I think I just needed to get it off my chest

     

    Im glad they got in contact with you - is there any official line on this matter? Id be more reassured if there was actually something in writing.  It does look like it is quite a widespread issue http://www.macworld.co.uk/mac/news/?newsid=3374185

     

    thanks

    Excellent news!  FWIW Apple recommends keeping it plugged in for a couple of hours after the LED on the MagSafe connector turns green to ensure a full charge.  The initial battery reading will always be pretty high.  It takes my MacBook five minutes or so for the "real" readings to appear and stabalize...depends a lot on what you're doing at the time as well of course.

     

    As mentioned Spotlight will be indexing for a while (and draining the battery quickly) after a fresh install.  Once it's done and you have a good 3 or 4 charges cycles under your belt things should settle in and hopefully be good for the long haul.

     

    Enjoy and keep us posted.

    Agreed, any CSR denying anything if in fact they know better is a bad way to go.  I know they need to run their diagnostics and all, but after that they should always be honest and up front IMO.

     

    Apple has no official line other than that they're aware of it and working on it.  They almost never ever make any statements beyond that. 

     

    I saw that linked article a couple of months ago.  ML was released to the public July 25th.  That piece and several others were written right after that...many based on posts from this very thread.  Other than a couple of more articles published later saying that 10.8.2 cured the battery life issue on some bench tested units it's been pretty quiet.

     

    None of the ML updates officially mentioned improving battery life for MacBooks, but at least the last one clearly did for many folks.  I expect there will be more to follow shortly.  Hopefully that'll take care of the rest.  We'll see!

    My macbook air drains all its battery during sleep mode. Im sorry I couldnt read all the 177 pages...do anyone know if this has come up and fixed?

    Hi everyone,
    I've got a similar problem but i think mine is really extreme.

    I bought a macbook pro mid 2009  around early 2010
    I have the OsX Mountain Lion and the battery problem

    Some times it just shutdown after 15 minutes of using if i don't connect it to the charger

    and after installing coconutbattery, it said my currently battery capacity is araound 8% after 344 loadcircles......how is that possible?
    after a while i checked it again and now it's 75%

    is it just a OsX problem or really my Battery? I really did take care of it but how can it be that criticaly?

    Full charged it last for araound 1 1/2 h

     

    Is there a way to fix that problem?

    Don't really want to pay 150$ for a new battery-.-

     

    Thanks

    Contacted the Apple Support again and they promised me to solve the problem. I was hardly ******, because I already heard that from two other Apple Senior Technical Adviser, but then I never heard again...

     

    My battery life is now 84%.. it was 92% a week ago. Nice...
