Extend battery life for latest MacBook Pros with gfxCardStatus Laptop Macs
When your MacBook Pro switches from integrated Intel graphics to the dedicated GPU, power consumption goes up considerably. Which API calls or program attributes trigger this switch is not totally clear, and programs that you least expect might be draining your battery.

Cody Kriegerís free gfxCardStatus will tell you when a switch occurs and lists which programs are causing this. (It also lets you manually toggle the mode.)

I found out, for instance, that EagleFiler and Twitter both triggered the GPU, significantly reducing the time I could run on battery. (EagleFiler's author is investigating this.) Neither program is particularly graphics intensive, so I'd never have suspected that leaving them up (and hidden) would be draining my battery prematurely.

[kirkmc adds: Since I now have a new MacBook Pro with Retina display (wow, that display is nice!), this hint comes at just the right time. This utility has been around a while, yet it's never shown up here as a hint. Jeff Carlson reviewed it for Macworld last year, so you can read more about it there. One thing I can say about the new MacBook Pro is that the battery life is orders of magnitude better than my late 2010 MacBook Air, and with this utility, I'll be able to use it even longer.]

I agree this works very well have been using it for years with 100s of machines. It squeezes a bit more battery out of your notebooks.

One problem with it for me is i run loads of Virtual machines which it does not play ball with so i have to be careful to make sure i turn it back to dedicated card and quit it before i open my VMs.

I literally cannot thank you enough for posting this, the nvidia GPU on my brand new retina macbook is screwed, this app let me realise why my display isn't always unusable, and also let me force it to always use the internal GPU.
Until apple have enough in stock to allow me to swap it over without leaving me 5 days without a machine this is an invaluable stopgap.
Should anyone want to see what I've been coping with for the past 2 weeks see http://www.youtube.com/watch?v=lrRhlGzI5ak

Thanks again!!

one day I look forward to actually playing with the full power of my just short of £3000 of machine...

I'll be able to use it even longer.

It's funny, that the "even" more/bigger/longer/better/faster is now always connected to Steve-Jobs-Speak.
(for me anyway)

:-P

I found when using gfxCardStatus on my 2011 MBPro, that Growl - specifically GrowlAppHelper - set it to discrete permanently. If i deleted the GrowlAppHelper plist, it reverted to the Integrated setting. The problem was that as soon as Growl made another notification, it reverted permanently to Discrete again.

I contacted Cody at gfxCardStatus and he told me that some Themes cause this to happen. Change the theme to something else and then quit and restart Growl. I had downloaded a couple of new Growl themes & they were causing the problem. Growl behaves again, as far as graphic cards are concerned.

I am posting this to help anyone else who might have come across this same problem.
With thanks to Cody for his speedy reply & fix.

The latest version can also force "internal only" only when you're on battery! Amazing!
