Battery drain after SSD upgrade

    Just upgraded my Macbook Pro 13" mid-2009 with a Crucial MX100 128 GB.

    It's definitely runs faster now, however, now the battery last for a significant shorter time.

    I am running yosemite.

    The list below is everything I have tried so far:

    1. Reset SMC/PRAM/NVRAM

    2. Checked (using activity monitor) if there was an application hogging the power. There wasn't.

    3. Switched out the SSD with the old HDD. The was no battery drain problem with the HDD.

    4. Checked if there were any driverupdates. There wasn't.

    5. Lastly I tested the SSD in another Macbook Pro 13" mid-2009 running Mavericks. In this case there was no noticeable batterydrain, but no increased batterylife either. (Shouldn't the SSD increase batterylife??)

    So for me it seems that yosemite could be the problem when I use the SSD.

    I really don't know what else to try.

    Really hope there is someone out there who could help!

    An SSD is unlikely to cause MORE battery drain, over a spinning hard drive, except for that first few hours (maybe as much as a couple of days) while a new drive is being re-indexed.
    When you say less battery life - HOW much less do you get
    Your MBPro is more than 5 years old.
    Is the battery original? Maybe it's time to replace your battery?
    If you go in to your System Information, then the Power section, you can see some information about the health of the battery.
    Part of that is the Charge Cycles.
    How many Charge cycles (or Cycle Count) on the battery?
    What is the Full Charge Capacity listed there?

    You said that you just upgraded to the SSD... How long have you been using it?

    Look at your Activity Monitor - make sure that you are viewing All Processes, and not just My Processes.

    How much RAM is installed?

    With the HDD it could last roughly 5 hours, now about 2-3 hours.

    Number of cycles: 1292

    Full charge capacity is 3999 mAh

    I have been using it approx. 2 days.

    There is 2 ram installed.

    How can I see if it is still indexing?

    Only 2 days?

    2GB of RAM is not too good for Yosemite.

    Problem is likely that the indexing of your hard drive just has to work too hard, and you have not let that complete yet - and only 2GB installed is working against you.
    If you used the old hard drive, then that's likely still on an older OS X version, right? and even with Yosemite, wouldn't still be indexing, if you have used it for quite some time - so not so much battery drain.

    I bet if you go into your Activity Monitor, then click on the memory tab, that the memory pressure is yellow, or even red - and lots of page outs (high Swap used number)
    That will certainly be a high energy user, and suck the battery right down.
    And, does your Battery Health show "Service Now" - or something else besides "Normal"
    The design life for your battery is 1000 charge cycles, and you have exceeded that, too. That can mean that a little more use can move much more quickly to drain the battery.

    So, your upgrade (to SSD) is only partially complete - you need more RAM.
    Your MBPro can max out at 8GB, but even doubling to 4GB would help significantly.
    I expect that the battery use would also drop to normal, once you get the memory pressure to a normal amount (generally green)

    No the old drive was actually also running yosemite.

    You can check out my activity monitor in the file attached. There is no yellow, or red.

    Also I checked my battery, it says normal..

    Could it be because TRIM is not enabled for third party SSDs?

    Newegg lists the Crucial MX100 128GB to use 0.1 (idle) to 0.15 (active) watts. That should be lower than your spinning drive.

    Something else must be going on with your system. It is probably indexing lie others have said.
