    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.

     

    It doesn't at all. As you can see there are users withouth a discrete GPU experiencing battery drain.

    Moreover: what you claim as longer battery life (6-7 hrs) is the estimate time or the real usage time?

     

    If you claim 6-7 hrs of real usage of the battery, than please post your logs.

    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.

     

    I was getting these battery drains with a clean Lion install and without even installing flash player.

    Try to watch a video with Safari, which its codec isn't supported by QuickTime X and you'll see:

     

    • QTKitServer process running at 100% CPU;
    • discrete GPU being kicked in if your laptop has one: it's normal because the conversion of the data stream shouldn't affect CPU usage and drain shared memory. Which is exactly what doesn't happen, cause CPU usage goes crazy when QTKitServer process starts the conversion even if a discrete GPU is present and the system swithces to it;
    • as concequence from what described above, temperatures of the laptop will raise a lot and fans will start to run at 3000RPM and more.

     

    Try then another test: leave a PDF document opened in Peview.app in full screen mode. No discrete GPU switch will happen, but battery time estimate will drops a lot, and also real battery usage will be shorter.

    After a full charge on my 17 inch MPB, I booted up this morning and it took 5% of the battery to boot up.   It said 2:52 minutes left, and now 20 minutes later it says 1:33 left.   I will be lucky to get a full hour out of this battery that got 8 hours a couple days ago. 

  • DucatiMonster Level 1 Level 1 (0 points)

    50 minutes later, it is down to 50%.  So, 70 minutes total to get to 50%.  The only thing I have done is posted the previous post on this site and this one.  Otherwise I have been away from my computer.   I was going to call Apple, but my brand new iPhone 4S was completely dead this morning!!   Less than 8 hours of standby????????  

     

    *** Apple!   Great way to show your customers you care!   It has been at least 5 months of these reports and you haven't even admitted the problem.    Apple has successfully ended the wireless age for their products.   Everyone will know you own an Apple product because you will need to be tethered to a power outlet.   

  • Nickofari Level 1 Level 1 (0 points)

    Same problem(s) here.  I've had two AppleCare calls, and two Genius Bar visits to troubleshoot the decreased battery life under Lion.  At the last Genius Bar appointment, they said I need to check-in my computer so they could diagnose the problem more deeply.  It's a reasonable approach, but not for me. If I had an extra machine, I would do this, but as my MBP is my primary work computer and I can't work without it.  Even with AppleCare, Apple suggested that I buy into the $499 Business Joint Venture program so they might provide a loaner.  Disappointing to be sure.

     

    Any ideas to how pervasive this issue is?  There are 80 pages of posts here, but that hardly represents all mobile Lion users.

  • DucatiMonster Level 1 Level 1 (0 points)

    7:12 to 9:36.   2 hours and 24 minutes with about an hour of posting here and the rest of the time standby with the screen off.  This is on a 17 inch MBP that should get around 8+ hours and did a few days ago before I downgraded to Lion.   My 13 inch MBP gets less than 2 hours on Lion.   Apple is becoming worse than Microsoft was a few years ago. 

     

    Here is what I dont understand.  When I switch to windows in bootcamp, I get the same crappy bettery life.  Does OSX still manage the power of the computer in bootcamp?

    You'd better not rely so much on estimate timing at the moment. Check your Console logs, instead: diagnose reports -> look for powerd. This way you'll get the real battery time.

  • DucatiMonster Level 1 Level 1 (0 points)

    Please read the post I just made prior to yours.  You will see that I managed 2 hours and 24 minutes with most of that sitting with the screen off.  If I was actually doing work, I would get much much less.  Also, it says it is going to take 5 hours to full recharge the battery.

    Yes,I've got it now. I tought you were still talking about estimate time. The 5 hrs time to charge is really weird too!

    Do you get the same recharge time on Windows too, using Bootcamp?

  • milwaukee_bronze Level 1 Level 1 (0 points)

    Thanks Rayced,

     

    If you read the 2nd Sentence of my post I'm pretty sure I made it clear this might not help eveyone.  Just adding my expereince to the collective. - Sorry if somehow that offends you.

     

    Let's just hope Apple finds a solution for us all.

    Was at the Genius Bar over the weekend. They were optimistic that Citrix (which several have mentioned here as being problematic) might have been the issue for me, only to discover that I had previously uninstalled it (I was initially unsure whether the uninstall worked). They remain at a loss on the battery life issue generally, other than to acknowledge that it is a problem for many. 

    Like the current iPhone4S battery problems (which I also have), it affects old products, new products, those with the software native on the machine and those who have upgraded from old software (including those who did fresh installs after experiencing the problem). They just can't figure it out.

    And in the process, Apple loses the competitive advantage of machines you didn't have to carry around power cord all the time to use.

    I switched to Apple products in early 2010. You couldn't find anybod more excited and enthusiastic (and more of an evangelist) after making the switch. Now I have a phone that can't make it through early afternoon and a computer that is topped off at 3 hours (if I'm lucky) of battery usage with very minimal use (which got 5+ every time before Lion).  And Apple seems completely unable to solve either problem.

    I'm not going to stop cheering for Apple just yet, but I'm about to put down a pom pom.

    Frustrating and disappointing. I only expect better because Apple set the expectation.

    Interesting read and wonder about the relationship to some of the Macbook Pro battery issues.

     

    Cheers

  • Video Guy Level 1 Level 1 (40 points)

    I can agree with that. I left my Mid 2009 MBP idle on the desktop, display on, computer awake for an hour. Menubar battery estimate (wich we know we can't always trust - but is still an estimate based on the current computer operation) read 85% - 7:25hrs. Fire up Safari to visit this forum, and an instand drop to typical a Lion reading of 4:30 hrs. Come on! - Opening up one APPLE application cuts battery life nearly in half!?!

  • Saxphile Level 2 Level 2 (190 points)

    I'm having the same issue with a Mid 2010 MacBook Pro 15" i7. I have only background CPU usage (<20%), but the CPU draws 50+ W of power accoding to iStat. SMC reset helps, but it comes back after a while. My battery life is down to about an hour because of this, and it only started in the past few days.

     

    Very strange indeed.
