    I am in the same boat as the majority of you. I guess in my case I may have more of a reason to gripe and complain about this completely overlooked issue.

     

    I have recently purchased a 13' MBP a little after New Years this year and had better than expected battery life, typically around 7 1/2 to 8 hours with 7 or more apps running (iTunes, Twitter, Safari, Messages, eMail, etc.). Coming from a PC I was astounded. About a week to a week and half later Apple released the 10.8.2 update and my battery life went down considerably.

     

    Checked a few different kinds of battery life and monitoring softwares and each of which provided me with near identical data. My battery health went from 5770 mAh to 5562 mAh (about 96.4%), keeping in mind this is a brand new MBP. My estimated battery life from 100% starts me off with a 4 hour expectancy...with real world usage it tends to hover around 3 1/2 to 3 hours and 45 minutes.

     

    I've tried everything from the SMC reset to battery re-calibrations to completely changing the way I use my MBP....nothing has worked to correct the issue. I don't want to return my MBP for another because I don't think that it should be necessary for me to do so. ML 10.8.2 has to be the cause of the terrible battery life.

     

    It becomes increasingly more aggrivating when Apple continues to release updates for 15' & 17' 2010/2011 MBPs to correct their battery issues but completely ignore the 13' and more current MBP releases. I'm tempted to download a copy of Lion and downgrade my OS. Anything for better battery life. I mean, whats the point of having a laptop when it has to be plugged in constantly. Even my HP Netbook (which specs pale in comparison to my MBP) gets 5+ hours of battery life between charges.

     

     

    Apple has been asleep at the wheel on this one.

    I'm almost agree with you and support you in this question.

     

    Apple haven't solved the problem with buttery life in for MBP in Mountain Lion yet...

     

    P.S. And there is a strange thing. In Google Search there are no news about not solved problem )) Apple asked google don't show any? ))) There is only "10.8.2. has been solved the problem..." BLA-BLA-BLA. Bad job.

    It's not happening on all MBPs. Some seem to suffer, most don't. When they can fix it, they will. Luckily all my MBPs are showing great battery life. I suppose patience is a virtue.

    Well, I had high hopes that 10.8.3 would fix the battery issue with my MacBook Air but it's just as bad as ever.  2 hours maximum clock time with just wireless and browsing.  No Time Machine, bluetooth or anything  else running....  I guess I'll see about selling it and starting over with a mac book I can test drive for a day.

    Thanks for the heads up. I'll stay on lion even though the bastards got my money for ML.

    Today I updated ML to 10.8.3 and there is no result for my battery.

    What was the result your battery expected? Did you ask it?

  • Zaur Fedorovich Level 1 Level 1 (0 points)

    After previous update from Lion to Mountain Lion battery life lost about 2.5 hours. Upgrading to 10.8.3. didn't give any positive results. I expect restore to 5.5 hours )

    I had seriously degraded battery life under 10.8.2, losing about 1% per minute.  After several SMC resets did nothing, I restored my machine but experience no improvement.

     

    Under 10.8.3, things are much better.  I now get about 4 hours of battery life, which I see as reasonable for a 3 year old machine.  I don't feel like battery life is as good as it was under 10.8.1, but it's certainly improved over 10.8.2.

    That's great!  But I'm looking for the 6 -8  hours they advertised for my MacBook Air!  I get that with 10.7.5 but not with 10.8.x

    My MbA 2011 went from 4.5hrs to 1.5hr down. So I downgraded to 10.7.5 Lion.

    After giving it a full day of testing, there hasnt been any difference in battery life with the most recent update of OSX. If any I've seen a minimal improvement. This is becoming a serious inconvenience. Looks like we are waiting for 10.9 for a resolution...if there will ever be one. I'm very disappointed that Apple has not addressed this. Good luck to everyone in your endeavors.

    Only seems to affect a small amount of users. Four of my five Macs are MacBook Pros and none have suffered any battery degradation since updating to Lion then Mountain Lion from Snow Leopard. Wonder if its machine specific?

    After upgraded from Snow Leopard to Mountain Lion , the battery time droped down from 10 hours to 4-5 hours max. This is definately 100% a bug of Mountain Lion. And this i tell you for sure, as a PC user from 1983 and now as a Mac user from 2010. I would sugest Apple to do something and in the next release 10.8.4 this bug has to be fixed. Don't search for solutions, only apple can fix this problem.

     

    Except from this , Apple US has to support the Greek language more , for example the voices Alexandros- Melina when they anounce of the hour, it is very terrible, Apple US should work closer with Greek comanies who supports our Languange.
