    Yes, I thought the new SMC update fixed the problem... was getting 7-8 hours battery life UNTIL I plugged the power adapter back in later that night. Now it's doing what it had been doing: low, low battery life and running hot. When I do SMC resets, it works for a while but then it all happens again.

    IIhan Kudeki: Recent power upgrades have apparently done wonders for, say, the iPhone. However, it doesn't seem that improvement in battery preservation is associated with the latest SMC update.

     

    adretri: I share your confusion on what's causing the battery drain even during sleep. Thing is, I don't have USB or Bluetooth devices attached to my machine. Something in the OS 10.6.8 and above software requires additional power expenditure.

     

    It would be great if users could have the ability to shut off processes that sap battery power. I tend to rely on the MacSafe adapter most of the time, but that's only because battery life is so unsatisfactory. Other laptop manufacturers have encountered this issue on occasion, but not as globally as with the 10.6.8 and Lion upgrades.

    1 week old mbp 15 inch, no applications running, half backlight brightness, no wifi, no bluetooth, integrated graphiccs, 98% battery.  estimated battery 4hr30

     

    this is quite frustrating

    ... Yes same here as detailed earlier.

     

    Unless something is said by Apple soon I think I am going to have to buy a copy of Snow Leopard and downgrade my nearly new MacBook pro from its pre-installed Lion. I feel a bit annoyed about this but this battery life issue is seriously a problem for me - plus the fact that the machine cannot be relied upon to sleep without draining at least 10% of the battery every 24 hours.  With hindsight I am *slightly*  beginning to regret my jump to mac from windows  - I thought this sort of tinkering would be a thing of the past - sadly not. Please Apple, restore my faith!

     

    My final hope for Lion is with another poster who has informed us that Apple are looking into it seriously with his MacBook as an example.

     

    For the record, my machine has had all the resets, calibrations and os upgrades done and there is nothing utilising the CPU too much. Battery life in this 2011 Mbp is 4.5 hours at best -  usually much less.  Following an smc reset I do see a reported 8-9 hours but within a few minutes it drops by 5 hours never to return. Battery is in excellent condition according to battery coconut et al.  

     

    Returns to watching this space!

    i agree with everything you have said. this is my first mac, and after shelling out $2500 with applecare i am sorry for expecting at least close to the 7 hours that they have stated. i would even be happy with 5 hours at this stage. i sincerely hope that there is an update for this in the very near future

    Greetings to all.

    After checking my logs for powerd, I can state that the latest SMC firmware update is not going to solve battery drain under Lion at all.

     

    I'm still getting 4 hrs of real battery life. I'm just browsing the web using Safari and I have mail.app. and preview opened.

     

    I've watched a couple HTML5 videos during these sessions, making sure QTKitServer process would not be kicked (I'm using ClickToPlugIn). No Flash player installed at all, either.

     

    Screen luminosity was half dimmed too.

     

    During sleep the battery still drain about 1% every 2 hrs or so.

    Nothing was ever attached to the laptop via usb, firewire etc.during those sessions (both activity and sleep time).

     

    As mentioned before, SMC reset only gives me a longer initial estimate battery life. Therefore that suggestion reminds me of the hilarious "more cowbell" SNL sketch with Christopher Walken:

     

    "I've got a fever, and the only prescription is: more SMC reset!!"

    How can you see the logs for powerd?

    I have checked the console messages and filtered "all messages" for powerd without any result.

    Is there something else?

    You ought be an administrator user, in Console look inside diagnostic reports.

    Hi All,

     

    I wanted to add what I have expereinced to this thread.

     

    I too made the mistake of upgrading to Lion from 10.6.8.  I have a 15" MacBook Pro - Mid 2010.  In my situation it is certainly the discrete Graphics card causing the drain.

     

    The following apps consistently trigger the discrete card on  (Perhaps we could build a list of known apps by Model?) I identified these by installing gfxCardStatur v. 2.1 quitting all apps and starting them one at a time. If they triggered the discrete card, they are on the list:

     

    Firefox.app (8.0)

    Twitter.app (2.1.1)

    iPhoto.app (8.1.2) '09

    Garage Band.app (5.2) '09

    Skype.app (5.3.59.1093)

     

    I included the .app to verify, I am not talking about websites here but the actual aplications.  I have also verified that for all apps I am running the latest version I am entitled to.  IE: I have not purchased iPhoto '11 etc.

     

    I have spoken with Apple Support and over 2 days collected info about my mac and submitted it to Engineering. - I will let you know if I hear anything further.  Apparently it takes some days for the engineers to come back.

     

    I work in IT and would encourage any of you to report your experience. - The reasons are two-fold:  1) The more info availbale to these guys, the better chance of finding the cause.  2) The more people reporting it, the greater severity it will have for resolution.

     

    In the interrim, the best fix I have put in place was tipped earlier in this thread:  Install gfxCardStatus 2.1 and configure the preferences like this:

    Screen Shot 2011-11-13 at 1.48.36 PM.png

     

    It's certainly not ideal, but forcing to Integrated at least gets some of my battery life back.  I am hoping the days of 6:00 hours are not gone without the effort of going back to 10.6.8.

     

    1 last point,  Don't always rely on the battery meter remember it's only a calculation / estimate. The best way is to verify runtime through a full charge and then time how long it takes to drain.

    Agreed using gfxcardstatus is a help.

     

    The big mystery for me at the moment is why, when sleeping the MBP drains its battery at 2% per hour.  This is when all apps are closed (completely) and nothing is attached via usb / bluetooth / firewire....

     

    When the machine is shut down, I can confirm no battery drain at all.

     

    It is my belief / theory that this 2% per hour drain when sleeping may be linked to a somewhat substandard battery life when not sleeping - whatever the OS is keeping constantly on when sleeping is, perhaps, contributing more than an additional 2% extra per hour when the machine is awake.

     

    Hopefully this means just a bug fix in an OSX update - and soon...

    Apple called me again to get more logs. They promised that they are working on the problem.

    Just today, I updated OS Lion with the latest firmware for the SMC update.  I'm hoping this is the solution we all need.

     

    Good luck to us and to apple support

    Watching at logs I didn't find any OS activity during the sleep time.

     

    PS: IMHO gfxcardstatus is yet another "cowbell": in my tests I had never let the discrete GPU to kick in. Moreover there's people having this issue with laptops which do not have a discrete GPU at all. Finally I wasn't ever botherd by thinking about which GPU was at work in SL: the battery was lasting longer even using flash player to watch some videos.

     

    @jess: I haven't had any improvements in battery life after installing this new SMC firmware. It addresses some other issue.

    Just checked the logs on my MBP from putting it to sleep then waking 45 mins later - I too found nothing to report - no activity at all - but battery still went down from 45% to 42%... 

     

    :-(

     

    Reason for doing this was testing after cutting back on all apps and tools from 3rd parties (apart from a couple of work essentials)..  well that didn't help.

    A further $0.02 The Discrete card makes a massive difference on my machine.  I'm not saying it's the only cause of this drain, but in my situation with the MBP mid 2010, it most certainly does.  If I stop gfxCardStatus from forcing to integrated and start Firefox, the system immediately jumps to discrete and battery life calcs slice almost exactly in half.  In My experience, the laptop at this point will last a max of 3hrs (real time) not calcualted, from a full charge.

     

    Using gfxCardStatus to force integrated on always returns closer to the 6-7 hrs I am used to.

    I just upgraded to Lion yesterday and my 13" MBP gets at most 2 hours on a charge and my 17" MBP gets about 3 hours on a charge and periodically won't charge.    In the last hour on the power adapter, it went from 9% to 16%.  Very very slow charging.
