OS X Lion Battery Life

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 :-)

I found a thread that helped me solve this battery problem. perhaps you want to have a look:

now my MBA seems quiet and efficient as with Snow Leopard

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.

ok i maybe stupid but which is the option key?

starting from the space bar (in either direction), it's command, option, control

ahhhh the "alt" key many thanks

oh and i have now tried the reset and my battery life is better than before lion so thats cool 🙂

still lots of other silly problems though 😟

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.

This worked not as much for me on my MB Air (2010).

After resetting the power manager, the time left for my battery fluctuates from 2 to 3 hours while working with Safari.

On Snow Leopard I had up to 6 hours of battery life.
