    Let me translate mcgeist's post:

     

    "I have similar problems.

     

    with my MacBook Pro 13'' Early 2011 - 16GB - SSD 512GB approximately 2 hours less bettery time.

    Mainly when surfing the web - Watching videos I don't recognise it that much."

    I'm not Genius(tm), but if Apple Engineers were to simply check the RPM of the fans on the early 2011 MacBook Pros, they'd find that the default setting in OSX 10.8 is for roughly 3200-3300 rpm versus the 1900-2000 under 10.7. This would certainly account for the reduced battery life.

     

    Usually, I associated this with a runaway process, but according to my htop output, it doesn't look like it. Instead, it seems that the update changed this default setting.

     

    Please fix ASAP, or release 10.8.1.

    You are only talking to other users here, not Apple.

    Did not change my fan default setting.  They are humming along around 2000 and battery life is about the same than Lion: ca. 5hrs. running only Safari and Mail.

    I think I'm going to try a reinstall on ML before I try to revert to a Lion download. I've had the same troubles as everyone else in this post. My exhaust fan has been noisy as all ****. iStat shows that it is at a perfectly normal RPM speed, and Activity Monitor shows 97-98% User and CPU idle. My battery life is horrifying. I am beginning to regret the upgrade. I never had these problems on Lion.

     

    Mid 2012 MBP.

    Miy fan is doing the same thing. With nothing running at all, excluding Finder, the RPM ranges from 1997-2001, which is normal, but it would normally be silent. My brother has the same computer, and his is dead silent.

    Mountain Lion, after 3 hours of use, CCC running a clone, Mail, iCal and Safari active:

    Likewise, my default is 2000rpm (admittedly that's on an MBP 2009, not 2011).

     

    Try installing smcFanControl. You can set the default yourself.

    I have also had a drop in battery life after upgrading from Snow Leoprad to Mountain Lion. 

     

    My Mac...

    is not indexing,

    I have iCloud off,

    I have any push services off,

    Mail is off,

    No heavy tasks which consume a good amount of battery other than Safari and Mozilla for normal internet use and some word processing with Micrsofot Office,

    nothing is plugged into to any ports,

    Screen brightness is around 40%,

    CPU activity seems normal,

    Disk activity, I don't know what normal looks like. (There is  activity about every 6 to 8 seconds, spikes for both Data Read, and Data Written).

     

    Other than that I dont know what else to look for.

     

    My battery life meter fluctuates from 4-6 hours of remaining life.

     

    I am not sure if others are experiencing this, but I can hear some light spinning from the hard drive.  Its the lightest sound, it doesnt sound problematic, and almost unnoticable when theres alot of noise.  But I compared it to my friend who is running Lion and I don't hear any hard drive spin when the computer is just sitting there doing nothing.  On mine, however, its always spinning, it sounds like a really really really light fan, and I know its not the fan because the sound is coming from where the hard drive is.  If this is the culprit then it must be eating away at my battery since it's spinning all the time.  The only time I ever notice the hard drive stop spinning is after the Mac has gone to sleep.  Other than that, it's always spinning.  Is this normal?

     

    Anyway, hopefully this all gets resolved soon.

     

     

    Cheers

    Hi all,

     

    I have posted on here before. I have been playing with my 2010 MBP and ML done through upgrade.

     

    I am sat here with it on battery. What I have found (my view) is that whenever the discrete graphics card kicks in, things get hot, the fans start and the battery life tanks.

     

    Here are a few things I have found that make it worse.

     

    1. Connecting to an external display requires the discrete card to be active (on my machine at least)

    2. iPhoto requires the discrete card

    3. VMWare Fusion requires the discrete card

    4. Watching movies of any kind in browser etc requires discrete card

    5. 1Password needs to have the animations turned off in the preferences or it uses the discrete card

     

    Managing my use of these and installing gfxCardStatus to monitor it has helped me get better battery life.

     

    Once the discrete card kicks in, I am into about 2:20 out of battery. Without these and integrated graphics only (maybe even a reboot now and then to keep things clean), then I can get 5 hours out of the battery without too much trouble.

     

    I know this is far from ideal but then if we want to use graphics acceleration then it comes at a cost I suppose - not happy but accepted now.

    Well,

     

    I have the Answer , but not the Solution

     

    OS X Montain Lion are new Changes to Adapt the Os Lion to Retina Display

     

    and they sold it MASKED to improvements and others

     

    The only improvement is Tasks (Reminders) and Notes separates of the Mail and Calendar, 'incredible improvements'

     

    and other minors bugs

     

    And which is the problem?

     

    To adapt to Retina Display OS Lion; at the same as iPad, it consumes a lot of RESOURCES not neccesary if you have a Macbook Normal not retina

     

    Solution: I think returns to OS Lion and refund our MONEY cause to have separate Notes and Reminders , it is called 'Update' and no 'other O S'

     

    But they have to cover the Expenses developments Retina Display with OS Lion

     

    well, Solution for Apple, Increasing the Price of the Macbook Retina Display and dont waste more money on TRIAL and Lawyers against Samsung

     

    Competence is GOOD cause it makes you IMPROVE

    do repair disk permissions, and turn off all unnescessary services in the background, uncheck login items under "accounts" and turn indexing off

    Same problem here... At first I thought it was my problem but after a little research it seems like I'm not the only one.

    Indexing is not an unnecessary service, it's an important one!
