    Dr ed,

     

    If after reading this entire forum you still have not found your solution (calling Apple support, and fixing it) like the many others that did, then you require a pardigm shift in thinking. The problem is not ML, but your approach to a solution. There is nothing to fix other than your approach. You are welcome to prove this wrong. Had there been something wrong with your machine, any genius bar would have found it and recommended a solution. It is deductive you have not even tried because, at any genius bar i have been, regardless of staff (covering three cities), when they see what you describe they take action on any obvious issue. A draining laptop is spotted in minutes. I remember when they noticed the 3% drop in three minutes, how they created the work order and my machine was replaced with a brand new one. In the end, the issue was the battery.

     

    ML works as advertised, no more and no less, and anyone writing to the contrary, or hoping some 10.8.3 is going to make a difference is not in the same reality as most users. I said the same before 10.8.2- and it turned out true. 10.8.2 did not fixed the problems of most of those that posted. Case and point, you ladies and gents have 10.8.2. My prediction? 10.8.3 will not fix your faulty battery, old and improperly used, or suddenly dying one. Umm, prove me wrong in a  few days upon release? When youre back we shall know. I suppose some will return writing "Shame Apple! I am going for some other brand." But Apple will not be the problem. When Arstechnica did its battery review, 10.8.1 had some shorter times but was not experiencing 50% time leaks.

     

    They say quite a few things about those unwilling to listen. Thos that have not spent to replace batteries,  or done so under warranty, you have no say as to this problem other than vociferating inaction. The steps a genius bar will do are the fol:

     

    - Diagnostic. problem found? No

    - Reinstall Found? Yes or No If yes

    - Hardware replacement. Solved? most times yes. Not?

    Hardware replacement. Solved? Good.

     

    I replaced 4 defective MBa last months (check posts) for issues straight fromt he factory, including two defective batteries. In the end, solved. No wailing and pooh me vs Apple-will 10.8.3 save me? posting here in pain. Its funny.

    Late 2008 Macbook aluminum - 250GB HDD, 4GB RAM, NVIDIA 9400M

     

    Upgraded from SL --> ML. Previously got 4-5 hours of battery life on full charge. Laptop also ran cool.


    Since upgrading to 10.8.2 (clean install)... continue to get fluctuation of battery percentage. Laptop last 2-3 hrs tops. Also runs noticeably hotter. This computer does NOT have any apps installed.

     

    WHen looking at activities monitor, I notice that "repair_packages" is constantly running (while idling). Disk acitivity also high.


    I forced quit the process and activity/processes have slowed down considerably. Still wondering if this will battery life. Will continue to monitor.

     

    Any thoughts on this "repair_packages" process???


    Thanks!

    I've just replaced the battery in my 2010 Macbook Pro on Mountain Lion. After six charges, battery health is only showing 91%. I've had it less than a week and it's dropping around one percent each day. Is this normal? Will the battery health stablize or do I have a problem?

     

    Thanks

     

    PS  The old battery lasted 2 1/2 years and 1100 charge cycles. In sept, when I installed ML, the battery was still showing 87% battery health after a 1000 cycles. After two months on ML the health dropped to 80% and then the battery failed.

    Are you discharging your battery to 0% (or nearly) before recharging?

    Dr Ed, there are options for those who feel the need to enter forums with comments such as yours. It is called therapy. Am sure some must have suggested it already in your past (gf, relation). If you feel the need to come here and make amusing bellitling comments, the normal venue is therapy. Maybe that will fix your battery problem.

    Scartacus,

     

    If you just replaced the battery, and after 6 charges you are exhibiting the characteristics you mention, then you have one or several issues. Assuming the battery is genuine (all bets are off if not an Apple), then normally, higher Technical Service deems the logicboard as defective. One of the 4 MBAs that I replaced had a defective logic board, the trackpad did not work properly.  Unit should not overheat as it does. Even if you discharged to 0%, no way you would drop 9%. i have seen it loose 0.2 to 0.3 percent if going to zero, but then, on full calibration, it bumps back a bit.

     

     

     

    The overheating you are describing sounds to me like GPU. Do you ever use youtube, flash videos and leave the browser open ? That could indeed fire up your GPU.

     

    Oh, another thing. Tech Support told me that any fast drain on a MB, and a battery replacement does not repair it, at the very least they assume a defective SMC controller, which, again, comes down to logicboard replacement. Your one week test should also include a clean install without any other software, which would help reduce unknown variables caused by other software.

     

    Doing Word work, at full charge, an MBA battery should indicate 9-10 hrs:

    Hello !

    I see there are more than 200 pages of discussion. I am having serious problems after 10.8.2 upgrade from 10.7.5. The battery life is horrible and it has reduced to half ~ 3.5 hours. I contacted Apple and as a first step the resent the SMC but still the problem remains.

     

    Would like to know if any of you were able get the problem fixed ?

    I, along with some others, have reverted back to Lion or SL until Apple sorts this out.  I've outlined the process I followed earlier in this thread, which I believe you can get to here: https://discussions.apple.com/message/20329937#20329937

     

    After trying to help troubleshoot to determine root causes, I'm now waiting to hear what people experience with 10.8.3, once it is publicly available, before I venture into ML territory again.

     

    Good Luck

    Out of the 6 charges, I allowed the battery to cut out at 0% twice.
