    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.

    The SSD itself probably isn't the problem. Maybe you have an indexing process that's running or something.

    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.

    How does your overall CPU usage look?

    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.

    Read the instructions carefully and try again. Also, when you attach an image from another site, change the IMG tags to TIMG, so your pics won't be oversized.

    Take a screen shot and post it.

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

    That article also states:
    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.

    People in the comments section are reporting improvements, though.







    No word yet on if it makes Safari seem snappier...;)

    It certainly won't hurt to try it. The jury is still out on this one.

    Please note step 2 of the instructions, in bold text.

    It's good to know, but there's nothing in the screen shot that would indicate high resource usage or battery drain.

    Are you suggesting that I run the command?

    Or that every thing seems fine, so it may be the drive?

    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?
