    Coconut Battery shows today 88% of the design capacity of the battery. Yesterday was 90%... I don't want to buy a new battery next month... so I'm seriously considering finish with ML and downgrade to Lion but there is no "Lion" installation in AppStore... Any suggestion?

    As you'd have to wipe your drive anyway to downgrade, you may as well install SL from your grey disks and after that the Lion purchase should be downloadable from the Mac AppStore.

     

    Or if you have access to a computer/bootable partition with a lesser version (like SL), you should be able to download Lion from there, save the installer and use it on your MBP after the wipe.

     

    Maybe you won't even want Lion any more after a test run of your original SL.

    Thanks for all that options. The best for me will be reinstall SL from original disk and then download Lion and install it from zero. I'll try next week if Apple doesn't say nothing.

    I use an SSD, no improvements to battery. I didn't do a clean reinstall. I won't even bother.. Based on some of the posts here, it doesn't look like a clean reinstall will do much to help with the battery issue.

    I love many of the new features in ML and I've gotten so used to the short battery life issue since using Lion that I'm starting to just ignore it. I dont really need to be on the battery all the time thankfully and my iPad does a good job of sustaining good battery life when I use Wifi. I feel like having Wifi while using my MBP kills the battery.

    Apple has fixed a lot of the iCloud issues in ML which is great. I am able to overlook the battery issue because of this. But I do agree that it's a little unfair that they make us go through this. Especially since these machines are quite expensive, and the fact that I used to enjoy very good battery life during the SL days.

    Well it looks like people going to Mountain Lion from Snow Leopard are seeing the same problems as we've been having for over a year.

     

    I've posted over there. They are trying all the same old garbage we've tried (and failed) for the last year. PRAM / SMC / Fresh builds and all that...

     

    MAYBE, Apple will step up - but judging by what Apple told me, they can't fix it. It's the way the GPU now works.

    Yep, that's right, keepeing unnecesary programs closed helps a lot, but not enough to get back that battery performance, i've already posted this before, it was just an experiment;

     

    But, after few weeks observing the mac behavior, I realize the problem is networking a lot (let me explain this), what i do was deactivating my iCloud account, delete gestures i'm not using at all, unregister not important email accounts and my battery now lasts more than 5 hours even with airport enabled.

    So it's not the best solution, but it's usefull to get back the battery life time. Maybe i must try t configure iCloud sync propierties to avoid a real time sincronization of my files, but i'm really not using it.

     

    Fo example tonight, I unplugged my 13" 2012 MacPro at 11pm, now is 1:30 am and i'm still getting 5 hour more (that's what battery indicator says) and it has been really accurate since my little experiment;
    Display brightness les than 50% and always networking.

    Not works for me.

    Please post on this newer common thread now as well.

    Forbes has picked this up and the more people we see posting, I think the more attention we might get from Apple..

    Yes, Apple contacted me a year ago and said they were aware of the problem. Since they have been unable to fix it, I think they are obligated to downgrade the battery life they advertise. I bought two brand new machines that both had less than 3 hours battery life running Safari and Mail—far less than the advertised claim. Apple recently had to backtrack on false advertising in Europe with their iPads (and 4g networks). Now, they should be forced to backtrack with the outrageous battery life claim.

     

    The point is this: a laptop is for portability. Quite useless if it won't stay on for a cross-country flight or half a day from the office. Given that they are the most expensive laptops in the world, yes, it is more than a little surprising. As Forbes magazine recently wrote on this issue: "Not good, not good."

    Wow.  I really hadn't noticed this for certain until last night.  I thought my Macbook Pro 2.3ghz quad-core i7 was running down AWFULLY quick, but I've just moved and I wasn't sure how well it was charged beforehand, etc.  Last night I had unplugged it from charging all day and had it largely sitting still with Safari open while I ate dinner.  Went to surf a couple of websites and battery was down to 28%.  This all took place in roughly 1.5 hours.  I've never paid much attention to it before because this machine has been able to run on battery for about 4 hours in the past.  Often I've had it disconnected and used it all evening only to realize it wasn't plugged in when the battery warning popped up.  Something has definitely changed for the worse since I upgraded to Mountain Lion.  I love the OS, but it's definitely put the hurt on my battery!

    right now I have almost 5 hours of battery life (only safari is on). I have Macbook Pro i7 2.3GHz early 2011 with 7200RPM drive and 16GB DDR3 1600MHz memory. I will monitor the battery and post again if this changes.

    That may be so, but this is not the place to report, try this instead

    Ich habe vergleichbare Probleme.

     

    beim Macbook Pro 13" Early 2011 - 16GB RAM - SSD 512GB ca.2h weniger laufzeit im Batteriebetrieb.

    Hauptsächlich beim Surfen - Bei Videowiedergabe tritt der Fehelr nicht so stark auf
