    Peej18 You are not alone on this one from what I have been reading. Hopefully Apple will come out with a patch soon. Must be a leak or something. I not buying the slow your mail pulling ect. We should be able to run everything as before the upgrade with nearly the same usage.

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

    Battery life considerably reduced after upgrading to MLion(OSX 10.8).

     

    Details: Macbook pro 13 -  i7 Ivy bridge 2.9Ghz. Just 2 months old.

     

    Using only 3 tabbed web browsing. Tabs like gmail, facebook etc only. No other applications running other than finder.

     

    Before updgrage:

    showed more than 7 hours of battery life after full recharge with 50% brightness. Scrolling was smooth. Smooth animations while using mission control, app expose etc....

    ******************************************************************************** ************************************************

    After upgrade:

    consistently showing 4 hours 50 minutes of battery life only. And drains much faster and needs recharge in 3-4 hours with 50% brightness and switched off keyboard light completely. Also noted the laptop is heating up more after the upgrade.

    ******************************************************************************** ************************************************

     

    - Monitored everything like Disk activity, CPU, memory etc. Nothing unusual.

    - Tried to Switched off every ML features which would hav done this like "Notification Center". There is no way to do that. So took every applications off notification center. Scrolling is not smooth.. and animations while swiping fingers for mission control etc. are very rough.. The graphics of ML is not displaying it smoothly at all.

    ******************************************************************************** ************************************************

     

    All i want is to downgrade to Lion(10.7). Nothing more. It was working perfectly fine. smooth scrolling, smooth animations. better battery life.

    Apple please let me downgrade to Lion. How can i do that.

    elbow,

    Have similar time on battery after upgrade.  Turned everything I could, with no improvement in the battery life.  One can visibly see the % decreasing.

    Only good part is we are lucker than some whose battery is much shorter.

    Just adding my name to the list. Late-2011 MBP with fewer than 20 cycles and battery life is at best 5 hours with brightness turned down to half. No processes of note consuming CPU cycles.

    Totaly agree with the slowness of the animation, I guess this problem as well as many other problems need to be fixed in the coming update of mountain lion, I think also apple should make notification more open to other application like in the iphone. still many things to be done. I beleive that mountain lion has been released too early.

    i'm having much worse experience with my 6month old MBP13, after upgrading to ML, the battery wouldnt charge properly now, and i cant use it for really mobility, have to carrry the charger everywhere.  Didnt experience any problem with the pre-installed Lion.

    now i'm having doubts of upgrading the rest of my macs.

    i already brought my mbp to the apple service center, and the rep admitted a lot of battery problems cropped up after the ML release.

    I also have a Macbook Pro from 2009 (17", first unibody). Its been purring like a kitten, a perfect little beast, until I installed Lion. Now, my battery life is half of what it should be, or even more. Drains even faster. I am a light user, and I don't have a lot of large files on my hard drive, average #/size of programs.

     

    Even set Energy Saver to Better Battery Life. I am very disappointed, and regret upgrading. We need a fix. Was going to upgrade to Mountain Lion. Now, there is no way I'm doing that, especially after all the complaints you got for low battery life, after upgrade, until you have a fix.

     

    I absolutely adore my 2009 Macbook and am a loyal Apple customer. Lion and Mt Lion are a big disappointment.

    For all:

     

    the fix for me was the following commands.  I was able trace it to the citrix receiver process (AGAdminService) tagging the cpu and subsequently draining the battery in record times...I couldn't kill the process in activity monitor, had to run this:

    sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist

     

    After i did this, the fan went silent, temp went down and batter life is back to 6+ hours like it is supposed to be! 

     

    Hope this helps.
