I recently installed a Samsung 830 256gb ssd in my early 2011 13 inch macbook pro. i have lost about 20% of my battery's life after this "upgrade". i have done pram and smc resets with no positive effects. i have also enabled trim and repaired disk permissions. i migrated everything using carbon copy cloner. is this a normal response for this drive is a drop in battery life or am i missing something that i should have done after installing the drive? would a fresh install of everything by hand(i really really dont want to do this) help at all? i appriciate any info or insight on this matter.

MacBook Pro, OS X Mountain Lion (10.8.2)

    Adding an SSD should actually prolong battery life - just a small, small amount, though. I doubt that your problems are with the SSD consuming power. However, if you have a backup, it wouldn't be a bad idea to do a 'clean' installation of Mountain Lion, having erased the SSD first.

     

    I've heard of a handful of problems here with the Samsung 830 series - nothing major usually. But I've never heard or read of any SSD (and I have a Crucial) being the cause of a power drain. Sounds as if something else is causing your power drain and it could be OS or hardware related. Try running the Apple Hardware Test to see if you come up with any errors. If you don't, it sounds as if a clean install of ML is the next step.

    Installing a 256 GB Samsung 830 SSD gave my battery life a bit of a boost - about 20 minutes extra - so there's something else going on. To cover all the bases though if I were you, I'd open the computer back up, take the drive out, and put it back in. I doubt it would be functioning if it weren't seated properly but I've seen weirder things go on.

     

    Clinton's suggestion to run the hardware test isn't a bad idea. I'd also run Activity Monitor to check out the CPU usage. For a sudden loss of battery life my first suspicion tends to be a rogue process burning up cycles for no reason.
