I have recently changed to 120GB SSD OCZ-AGILITY3 in my MacBook Pro (early 2011).
I have immediately noticed a difference in battery performance. Maybe up to 30% decrease.
Is there anything I can do to counter or fix this issue?

Thanks.
 
How long have you had it installed?

Restart your computer, then open up Activity Monitor and under the "%" column, look for processes using more than 10% CPU when your MBP is idle.

Firefox jumps around from 3% - 19%

There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

This should answer most, if not all, of your battery/charging questions:

  1. Launch Activity Monitor
  2. Change "My Processes" at the top to "All Processes"
  3. Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
  4. Click on the System Memory tab at the bottom.
  5. Take a screen shot of the entire Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
  6. Post your screenshots.

That sounds pretty normal, about what I'm seeing on my mid-2009 13" model.

Do you have the old drive available to swap back in and double check that the battery life is actually that much lower?

Also, make sure to read through GGJstudios post. He's always got a ton of good info.

There was a recent article in cult of mac saying that a wonky setting in 10.8's migration assistant could be cured with a simple command line or two in terminal:

That article also states:
I can’t verify this myself, unfortunately, because my Retina MacBook Pro is yet to leave the Foxconn factory.

I've yet to see any verification that this has any effect on battery life.

I would also advise swapping back the drives to see if the battery time lengthens again. Be sure to clone the SSD to the HDD to make sure you eliminate the software as a potential cause.

OP> Grab that same screen shot except change the My Processes dropdown to All Processes.

Im running Snow Leopard on an early 2011 MBP.
Will this relate?

No, you don't need to purge and yes, everything looks fine, as far as memory and CPU usage. I'd keep an eye on the drive.

Thanks for your help, I am trying a calibration (see below), I'm just recharging after 5 hours of it being off and drained.

Someone on Experts Exchange suggested I try a " System Mangement Controller reset", is this sound advice for increasing battery life?
