I downloaded Lion last night and played around on it for a minute or two then put my MacBook on the charger and went to bed. I woke up this morning and turned on my white MacBook 13" with 100% battery. After just 3 hours, with my brightness on the second to lowest setting, my battery was at 35% so I stuck it back on the charger, waited until it was at 100% again, then took it off. Once more within about 4 hours my battery was dead. I never had this issue until after the Lion update. On Snow Leopard I could usually get 3 or 4 days outta my battery before I had to charge it. Anyone else having battery life issues after updating to Lion?

    Yeah I'm getting about 4 hours on my 2010 13" MacBook Pro since I installed Lion. The battery life is much worse than it was on Snow Leopard.

    It is very similar behaviour in my macbook air 2010. The fans don't stop. I checked with my activity monitor and there is an application called AGAadminservice which is using 98% of the CPU all the time!!!

     

    it seems there is an undocumented battery drain feature :-)

    This may not be an option for you, but I called AppleCare and had them help me reinstall Snow Leopard because there were a few bugs that were really a problem. I then restored from my Time Machine backup and now I'm back on Snow Leopard without any issues. I'm going to reinstall Lion probably after 10.7.1 or 10.7.2.

    I just called Apple support and they talked me through resetting the power manager, the battery now seems to be fine. I can give you the steps the gentleman over the phone gave me, it might just help.

     

    1. Turn off the computer.

     

    2. Hold down Ctrl+Option+shift

     

    3. While holding down these button, press and hold the power button as well.

     

    4. Hold all buttons for at least ten seconds.

     

    5. power back on the computer.

     

    For me that worked, i don't know how it will work for everyone else but immediately my power estimation jumped up to around 9:30 and 10 hours. Which is two hours more than i started with.

    I've tried reseting it with PhangirloftheOpera's suggestion many times. The fan went quiet at the start but became noisy again after a while. Prior to Lion, after a full charge it can last me for about 5-6 hours but now it's only 1 hour and it fluctuates too. Sometimes it will even say that it's not charging then it says that it's charing again. Is there any help anywhere, especially from Apple's side? Please help, much appreciated!

    I am having the same issue. Battery life went from 4-5 hours to 2-3 on my 2010 MacBook Pro 15". The Citrix Daemon is not running on my machine so it must be something else. Any ideas?

    Ok guys.

     

    This solved the problem for my MacBook pro from 2011.

    I wished it worked for me but the machine prompted me by stating there is no Citrix agent running.  I am sure there is some other bug in there that they have not found yet.  I think I may just go back to SL, too many problems to deal with vs. the machine just working.
