thank u very much.
anyway, we're all almost pretty sure about what's going on with the battery, how can we contact apple about this?
Got a tip for us?

You mean that there's a way to set so that the integrated GPU is the active one?
i bet if enough people complain/take note of this problem, there will be a firmware update in the near future to address the sensitivity of the graphics switching. Hopefully at least! i dont really do anything that requires a super video card, but sure would love a battery life thats a few hours longer than what i am getting now.
Hopefully a developer will come out with a utility so we can disable switching or atleast know when it switches over.
I also have the new i5 15" HR 2.53" 500gb 7200 RPM and my battery experience out of the box (and brightness set to half) is exactly the same as the author of the thread. I have seen my battery indicator read just barely seven hours if I don't touch anything after a full charge.
I have been surfing Safari for 15 minutes now from a full charge this morning and my indicator was 5 hours remaining exactly.
Battery life is very impressive compared to a PC...but my wife's 13" MBP from December gets seven hours quite often. Point being is her battery gets closer to what was claimed and we haven't turned anything off where as this new i5 is getting about 60-65% of the claimed battery life with the same type of usage. Not sure why in one instance Apple would get it right and in another get it so wrong.

Mine is showing close to 11 hrs when idling with no apps open.
After first charge it was a bit over 100% (6989/6900). Second charge was 99% (6850/6900).
I guess i'll get over 6800-7000 from charge to charge, it all depends on temperature in the room etc, so don't worry people!
I discovered why my new MBP has bad battery life!
As discussed above, my battery life at idle on my new i5 15" MBP is rated at 7 hours with no wifi and brightness set to minimum. A friend of mine also has a new MBP, but his says 11-12 hours at idle. I put both laptops side by side and made sure the 330M was disabled.
My laptop was using ~1 amp of energy according to iStat, while his was using ~0.6 amps. This would almost exactly explain the difference in battery life. However, when I started watching the same video on both laptops, our laptops began to use exactly the same amount of amps and had extremely similar battery lifes (approx 4 hours).
TLDR: My Macbook Pro, and likely many of the other ones mentioned in the other thread, appear to be DEFECTIVE because they uses too much energy when idle. What should we do?

Hey guys just a note don't look at your battery when your external display is plugged in... I made the mistake and the nvidia gpu was running... I was only shown about 3.5 hours on a full charge... so finally tracked that down... unplugged the display... mbp switched to the internal chipset and I'm back up to about 7-8 hours 
was worried for a minute !
but man that nvidia gpu is drawing a ton of power!

My battery indicator is jumping around so much I can't even tell how long the battery will last. I've got open iTunes (though not playing anything right now), OpenOffice document, and Chrome with 17 tabs. I think I've been on battery power for about 2 hours and my battery is at 54%.
Is anyone else's battery indicator (time left) entirely inconsistent?

I'm only reading 1 hour and 9 mins with 59% battery life. I'm using Windows right now, which I know gets worse battery life. The only programs running are Word, Excel, and Google Chrome. Seems really low. Should I have it checked out?
apple fanbois need to shove off and stop "bragging" about 9-10 hours of battery life
I have a 15" i7 macbook pro with a normal screen
real world usage, doing nothing but word processing and a bit of facebook here and there I get about 5 hours 30 minutes, most of these tests dont have guys using it consistently, its just some guy sitting around looking up a site then leaving for a bit while their mbp goes to sleep they start up again etc.

in my humble opinion, it doesn't work in the way you suggest. I've OVERpaid (given it's internal components) because I want something different from the rest. Battery firstly. On the website, 8-hours wi-fi productivity...I want that. 7 hours fine too, but not 5. If i wanted 5, I would have bought a sony vaio. I bought a MAC.
Its a software issue that Apple needs to fix. Until then, your gonna get 5 hours.
I do not believe 10-11 hours with wifi on...it doesn't sound realistic. I don't believe they will go 11 hours just sitting with the desktop up with nothing running and no wireless on.
Aside from the 330 switching issues, how the heck did Apple get a 8 to 9 hour estimate if some folks here at getting 5 hours at half or less brightness, just idling?
I'd hope it's a software issue, but those idle figures may suggest otherwise. You can't use much less energy than you do whilst idling, unless the code that influences idle battery usage is it itself broken.
I'm getting 11 hrs by idling at 50% brightness..
