    Same here.  I have a 2011 sandy bridge macbook pro 13 inch.  Previously running OSX 10.6.8 snow leopard with 6-7 hours of battery on full charge based on usage.  Since upgrading to 10.7 Lion I

     

    After 2 hours from full charge the battery has reduced to 40% drastically.  This is absolutley poor. Apple please provide a software fix asap.

    Sadly, I'm having this issue as well.  After "upgrading" to Lion last week, my battery life is dismal:  2 1/2 hours on a 100% charge.  I've tried everything I've read on this thread but still having this issue.  The first report of this was last July and Apple still hasn't fixed the problem?

    The problem with the battery life is due to the fact that most processes continue in the background even after we close the app. If it is an app with a dependency for gfx switching then the graphic card remains in discete mode and thus we lose battery juice. You could either switch to integrated solution or use Command + Q to really quit the app. Read this article for the macbook battery solution that I used. Of course it won't work for people with MBP 13s or MBAs. They could try doing the SMC reset or battery calibration and hope for the best.

    Problem solved!

     

    I was all set to go back to SL, but decided to look at the forum one last time.  As with many others in the forum, the problem for me was AGAdminService daemon.  (You can't see Daemons from the Activity Monitor).

     

    To see what Daemons are running and what's eating your CPU, run this:

     

    top -o cpu

     

    For me, this was at the top:

     

    646- AGAdminServi 100.1 05:44.39 7/1   1    76   N/A   N/A    N/A    N/A

     

    To kill the daemon, run this:

     

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

     

    Problem solved!  Worked for me, hope it works for you.

    Applications -> Utilities -> Terminal

     

    At the Terminal command prompt you enter:

     

    top -o cpu

     

    However, you can get the same information by using

     

    Applications -> Utilities -> Activity Monitor

     

    and clicking on the "% CPU" column header until the most active processes are at the top of the display (triangle pointing down)

    MacBook Pro, Mac OS X (10.7.2), 27" i7, MacBook, MacMini, etc...

    By installing gfxcardstatus I eventually solved my annoying battery drain problem. Thanks to everybody!!!

    Accutally, I have noticed that Skype causes the permanent change to AMD Radeon instead of the internal graphic card... Since I always have Skype on, that causes battery drain. I'm going to donate to the author of gfxcardstatus

    Hi, same problem here with early 2011 15" MBP. I went to the Apple store and told them about it. First they wiped the computer and re-installed lion. Problem persisted immediately. Then they replaced the battery- problem persisted. Now they say they are going to replace my logic board. Have bought apple care to protect me for another 2 years as I'm sure something else will come up.

    UPDATE: apple changed the logic board and now there is less fluctuation in the "time remaining" reporting. Only problem is, after a full charge, battery life is quoted as 2h 17 minutes at 100%. Have to go back to apple for the fourth time.

    Actually it works perfectly, it is normal that OS X Lion consumes energy like a vampire, specially.. when the airport and bluetooth are on, and running on heavy *** programs.. Some of my friends prefered to get rid of OS X Lion and went back running on OS X Snow Leopard which worked much better than OS X Lion, but I still hangin on to the King because I have no complain so far..

    What we really need is a free app / update that can actually stop the charge when the battery is at 100% to keep battery's life longer.. If it exists, please do let me know because I tend to leave my MBP to overcharge all the time.. I'd like to see when it reached (100%), it automatically goes (Not Charging) without pulling out the power cable..

     

    Cheers

    By the way, my MBP's retail code starts with MD, does that make any difference?

    Thanks. This worked for me or at least the initial results are really really good.

     

    I always never saw the battery of my new MBP 15" more than 2 to 3 hours. I guess I never paid attention before I had Lion and once I upgraded to Lion, it was always around 3 hours or less. Yesterday night I followed PhangirloftheOpera instructions. Restarted the laptop. Left the laptop plugged in since I had almost run out of battery before I followed PhangirloftheOpera instructions.

     

    This morning the battery life is showing more than 8 hours. BUTTTTT... in the time of writing these few lines, I checked the battery and it is showing 6:47 remaining. That's a bummer but still better than the 3 hours I used to see.

     

    BTW, right now I am running only Firefox. NOTHING ELSE.
