    For what it's worth, and im a new mac user (the last mac i had was a performa pc) I have a macbook pro 15" retina and the battery life was awful, I came here hoping for a solution and you guys had a lot of helpful suggestions. Anyway i did the dmc/smc reset, whatever its called, and it worked temporarily but the battery life dropped back down on the next shutdown cycle. This time i did the battery calibration, and turned off location services and **** if the battery life isnt over 11 hours remaining, and 98% after 35-40 minutes of regular internet browsing , email, chat. This combo really seems ot have worked for me! HUGE improvement. Really all i did was let it shutdown from low battery, let it sit overnight then recharged this AM. As well as the location services, which i have no idea if that made a difference, just wanted full disclosure. PS, before this I was struggling to get 3 hours out of it.

     

    Thanks guys!

    Finally fixed my issue with Battery Life in Lion/Mountian Lion.... Come to find out my battery was well passed it. 540+ cycles on a 2 year old battery for my 2008 MacBook Pro.

     

    Got a new battery in December and been cycling it. Should have better results in a week or so.

    What does "been cycling it" mean?

    Starting with a full 100% charge and letting the battery wear down til the laptop powers down to sleep mode, closing the lid (screen), and letting it charge until full.

    That is a very bad idea for a Lithium Ion battery, don't do it, you're shortening its lifespan.

    I'm still having poor battery life with my 2011 MBP 15.  I'm a fairly early poster in this thread.  I've called Apple, written to Tim Cook, posted several times in here, and have never heard anything from Apple.  Unfortunately I purchased my MBP because it was advertised as up to 7 hours of battery life for wireless web.  I can barely get past 3 hours of half brightness or less, and only having a browser open.  I've shut down almost every other process I can think of, except Dropbox.  I'm only loading Dropbox because not loading it didn't make a difference.  Still Bumming....

    I've got a mid 2010 15-inch MacBook Pro that dies in just under 2 hours with browser and mail active.  I've just installed Battery Health and found it charges to about 98% and shows 6 and 1/2 hours left with current usage.  My first step is going to be recalibrating the battery.  Next step will be to come back to this blog for alternatives.  Third step will be weighing whether to invest further in Apple's empire or retreat to Windows.  I can get a fresh box that fits what I do for about double the cost of having Apple (100 miles away) replace the battery for me.  Will let you all know the outcomes and course of action.

    Update to my original reply on this.  This is a mid-2010 MacBook Pro 15inch single processor dual core running OS X 10.7.5  I recalibrated the battery and still experienced the battery going away in just under 2 hours.  Additional observations:  even though Battery Health (free app) showed the battery at 96% the charge cord light was green.  There are 153 cycles on the battery.  Battery Health shows about 6 and 1/2 hours of time left, even though the battery dies in under 2.  I found this fix on another blog:

     

    Shutdown

    Make sure your charger is attached

    Press and hold the Shift, Control, and Option keys all at once

    While holding down the other keys, press and hold the Power On/Off button for at least 10 seconds

    Release all keys

    Power on the laptop

     

    Since doing this I noticed the amber/yellow light now shows on the charge cord.  The battery charges to 100% as shown in Battery Health.  The laptop stayed on under battery power for over 10 hours, including over 2 hours of regular use (overnight). 

     

    It looks like this is the fix and I just saved some bucks instead of having Apple put in a new battery.

    Bought a new 2013 Macbook Pro Retina 15".  Horrible battery life ~ 3 hours max. 

     

    As I am trying to get to the bottom of this I installed Cody Krieger's excellent gfxstatus tool - http://gfx.io.  Basically it tells you when the discrete graphics chip switches on. 

     

    One thing I have noticed so far is that in Firefox when I have Gmail up it switches the discrete graphics chip on and starts burning battery like no tomorrow.  I think its the Google Talk plugins that have a video rendering component.  I disabled all the Google Talk plugins and this seems to slow the burn.  Some articles on Yahoo still switch the graphics on - probably another plugin like flash or something.

     

    Anyway I'm going to run with just integrated graphics on and see how much battery life I get.  So far its saying I should be getting 5-6 hours on 82%.  Let's see.

     

    Hope that helps someone out.

    Check how much CPU your browser and other applications are using. In particular, some websites will sit there and chew cycles in your browser even when the page/tab is just sitting idle.

     

    I wrote App Tamer because I noticed one day that Safari was sitting in the background using 50% of one CPU while I was answering my email. App Tamer stops processes (including web browsers) in the background to keep them from doing this - you're welcome to download and try it to see if it helps: http://www.stclairsoft.com/AppTamer/index.html.

     

    You can also just close the offending tabs in Safari, Firefox, Chrome or whatever browser you're using, of course
