    I have a MacBook white mid 2009 and upgraded from Snow Leopard. So far I have not tested the battery but I have noticed that the machine gets hotter. Especially in the area where the battery is located. Actually it gets so hot that I wonder if this does not damage something. As a result I can constantly hear the fan.

     

    The interesting thing is that I only run Chrome(flash disabled), Mail and Calendar, so basically I do web browsing. According to the Activity Monitor the CPU is around 97% idle.

     

    I hope we see a fix soon.

    My battery life has been degraded by 1/3rd since the upgrade to ML. Even when having no apps open, my drain is signifigant. Where I used to get about 7 hours from a full charge, I am now getting 3-5 depending on conditions.

     

    Only processes I am seeing more use from is WindowServer and SystemUIServer, but their increased CPU usage is sporadic.

     

    I am in the middle of draining my battery now in hopes to "reset the clock" on it, but we'll see what happens.

    Hey,

     

    I have the same problem, at the beginning I thought that it's because I changed my hard drive to an hybrid.

    The battery has now an average time I think of  perhaps 1,5 h.. If I'm lucky.

    The bottom of my mbp is so hot that my balls boil. Also the fan is very often on and extremly loud.

    I hope this issue will be solved very quick... If it would be winter, I wouldn`t have to switch on my heating at home, but during summer time it`s contra productive

    P.S.: I also fixed the rights of my hard drive, like I read in the forum, without any changing, or only with very little improvement.. the fan isn`t activated so often any more I think.. but it still boil my... you know!

    Following my post on Friday, I received a call from a very senior AppleCare person yesterday asking a variety of questions and collecting data on my mid-2011 i7 MBA.  They're coordinating directly with the engineering team.

     

    I'm not trying to be an Apple fanboi here, because this is a really big whiff on their part - very annoying from a user perspective, and stunning that it made it through QA on the release.  That said, they are very, very aware of this problem and its severity and are working very hard to try and isolate it. 

     

    I strongly believe they will isolate the issue and quickly release a patch.  I do hope that it happens before I wind up wasting too many battery cycles as a result.

     

    To wear the fanboi hat, though, for a minute, I do have to compare/contrast Apple's support reaction to this problem with the even worse situation when Iomega's NAS devices suddenly wouldn't work following Lion.  Iomega was completely silent, and as far as anyone could tell, didn't care and certainly didn't reach out to users or give any sort of information.  I will never buy another Iomega product again.  The jury's still out here, but Apple's support organization definitely has won the benefit of the doubt from me.

    As there are other issues with my MBA 13" (4,2) and I will have to go to an Apple dealer (Alpine Switzerland, no Genius Bar, not in St. Moritz either), I erased and re-installed Lion (10.7.4). Battery performance is improved. With 88% 4:41 hrs are left and Mail, Safary, SysPrefs and About This Mac open). When running on battery and quitting all but Safari, then currently: 87% charge, 6:03 remaining. It appears that returning to Lion does have an effect and positive one too.

    I notice that when I leave my 2011 MacBook Air on the charger after it's fully charged, it gets warmer than it ever gets when I'm actually using it. I didn't notice this to be the case until I enabled PowerNap.

    Greghei1 - Fanboi I hate to rain on the your Fanboi parade but you need to check out this thread that's now over a year old. https://discussions.apple.com/message/19031237?ac_cid=tw123456#19031237

     

    Back in Nov / December, many took calls from senior tech support people about this same issue but sadly, they couldn't crack it and all went "completely silent" for the next 5 or 6 months. It is ONLY because of the release of ML that the problem is rearing it's ugly head again and have got their attienion. I am again, like you working with the senior techs because they are taking it seriously - once more. They have even gone back over my old logs.

     

    Fingers cross they will nail it but we are a year into this problem and it's obviously effecting more people. For me that's good, I've lived with the problem for so long I just put it down to the "new normal" for Macs.

    Suggest we all "Rate" the ML download appropriately in the App Store and put down the comment why - I sure have and that will get their attention as hundreds/thousands low rate the new OS based on poor batterly life.

    what about this apple How is it possible to only charge your batery 97% all the time what happend to the 100% can you explane this? fix it ASAP! cause my batery drains so fast now!

  • GerdKuehner Calculating status...

    Same problem on my MBP late 2011 after installing ML. Battery-Time is nearly half time bevor installing ML.

    Apple, please make something with an update!

  • Willem1955 Calculating status...

    Hi, I own a model 2009 MBP. When using snow leopard, I had 7 hours of battery life. After that I switched to Lion and the time dropped to half that time. Hoping for a solution I installed Mountain Lion, but the problem remains. The energy consumption has risen to an uncomforteble height: when I use the MBP on my lap, the difference in heating up as considered to snow leopard is remarkble. Muy conclusion is that the operating system consumes a lot of extra energy now without use.

     

    I hope that apple wil patch this as soon as possible, because I use my MBP very often on the road, and I certainly need that battery life of  hours!

    Agreed that the jury is definitely still out on this one.

     

    I don't remember that there was as much public attention on the Lion problem as there is on this one.  Even my wife (a non-techie and definitely not a "fangurl" (yech)) had heard about it.   Hopefully, that will focus their minds a bit more closely.

     

    If it's a broad-based problem, and battery life under all conditions really remains half of what they quote in their marketing materials, they have real issues.

     

    I've stil never seen proactive communications from senior internal support and engineering teams to the users based upon support forum posts before, though, so I'll give them credit for that.  Partial credit - final grade is still Incomplete.

     

    Hope springs eternal.

    Just to add some more information to the thread, so hopefully those with problems get a fix: there must be a relation between the short battery life and the excess heat your Macs are generating. Again, I'm one of the lucky ones that got better battery life in ML, and I can report I also do not have any of the excess heat issues nor are my fans running. It runs as cool as Lion did. So whatever is causing your Macs to run hotter must also be causing the poor battery life.

    For what it's worth, and as encouragement to many out there who I'm certain are as angry & frustrated as I was with my brand new MBP 13in i7 (2012). I was really considering just boxing it back up and returing it. I too was running a migrated Lion system from a 2006 MBP. I too was getting lousy but acceptable battery use prior to ML and VERY HOT temps with fans going most of the time. Too hot to really even use on my lap at all. The situation got even worse with ML, cutting my battery performance by less than half and still very hot.

     

    I'm no engineer, so I don't have a clue why I no longer have this problem at all. I'm now 6 days into enjoying no heat generation, quiet, no fans and about 7-8hrs of battery performance. So, something that I did evidently fixed my machine and it's obviously software related. I forgot to mention the over-heating issue to the Apple dude that called me, but I also forgot to mention that I also disabled JAVA in Safari & Chrome.

     

    I expected that my problem would creep back as some here suspected, but I've been using my machine every day for the last 6 days and it appears all is still good.

     

    To recap, this is everything I did. Not sure which thing had the biggest impact or if it was a combination of factors. Here's what I did on my machine. (This may not have any impact on your machine):

     

    Reset SMC (a few times)

    Reset PRAM (a few times)

    Repaired permisions (a few times)

    Turned off SugarSync on launch & eventually just uninstalled since I don't really use it much

    Turned off Dropbox on launch (since I only need it open about once every few days or so)

    Updated Dropbox to latest version

    Turned off Mobile Mouse Server on launch

    Disabled JAVA in Safari AND Chrome

    Have uninstalled Flash completely, but will likely reinstall with latest version since I just wanted to make sure I was rid of any old versions of Flash

     

    That's pretty much it. I was having just as horrible an experience as anyone else here, but mine seems to be all good now.... even better than before with Lion or SL.

     

    Maybe it was the multiple times I reset SMC/PRAM & repaired permissions? Maybe a combination of everything? Maybe all the problems will come back in a week? Who knows... but for the moment, I'm enjoying the machine I thought I was buying.

    Hi golden_jubille,

        I too have a white 13" macbook that I've just upgraded to Mountain Lion and it exihibited the same things as yours, it got inexplicably hotter and battery life looked like it was just being drained for no reason at all. I did searches on the web to see what people have tried only to read that it did nothing to correct the problem. 

         However I've tried a combination of things and it looks like it might of at least helped my battery life (not sure if its completely back to normal, but it's lasting longer) and its definitely restored my laptops running temperature back to normal!

     

        Could you try these few things and see if you see similar results;

     

    In System Preferences:

    1) Personal -> Notifications, I moved everything from "In Notification Center" to "Not In Notification Center".

    2) Internet & Wireless -> iCloud, I unchecked everything and allowed the data to be removed off the macbook, then signed out of the account.

    3) Internet & Wireless -> Shared, I unchecked everthing in the list that was "on".

    4) Shut down the computer.

    5) Connected the power supply and made sure the battery was recharged fully, waited 1 full hour after the light went green.

    6) Still connected to the power supply I reset the SMC by holding Shift + Control + Option + Power Button for a second or two and released them all together, then powered up the laptop. Once booted up I disconnected the power supply.

     

    Since then the laptop has not gotten hot and it appears the battery is somwhat back to normal. I think I've covered everthing I did. Please let me know if this works for you too.
