Hey people!
I have a MBP 2.2 GHZ Santa Rosa with 10.5.1
I get at most 2:45 mins of battery life with only preview running at min brightness and all wireless off.
I even killed Dashboard to save cpu cycles, but no go
I'm on my third battery from apple. they claim that my battery life is "within spec. I have never seen 4 hours on the battery meter, let alone have the computer run for that much
The battery has 14 cycles and a full charge 5279 mAh
Tried smc reset to no avail...
Any suggestions? Can you guys please post your battery run-times?

That's definitely odd. My battery has a full charge of 5408 mAh and has 9 cycles. I get ~4-5 hours depending on use...
It seems like another component of your MBP is draining the battery. The video card perhaps? -

My battery full charge is 5110mAh, and has dropped down to 5106mAh with 59 cycles. I get about 4-5 hours as well. -

314 cycles... 2229 mAh... about an hour of life. about 15 months old.
According to Apple, the batteries should be able at 80% life at 300 cycles. And considering that no one can meet that... We should have free battery replacements until they can give us batteries that can go the distance.
When it was new I was able to get 4 hours on min brightness and little usage. Sometimes 4.5. And this is with the CD, the C2D have better life than these.
I know one fact about batteries... the hotter they get, the faster they get worn. And considering how the battery is one of the first spots to get hot, I bet thats why they don't last very long. -
Thanks for the response guys - you guys get 4-5 hours since you have the macbook (integrated graphics), not the pro (discrete graphics)

Hollownail has the older gen MBP. I have the 15" SR MBP and it gets just over 4 hours when I'm running without wireless, half brightness, with iCal, Address Book, and Pages open. I even ran iTunes for half an hour. 93% health, 46 cycles.
Exchange your batteries again, and if all else fails, get a new MBP. You don't deserve to get shafted.
Unless you're a child molester. Then it's karma. -
if you think those numbers are bad try booting into vista. 1.5 is the best you'll do there -
Yup, I do have the revision of the original MBP, so my life is a bit shorter than you guys with the SR platform.
Yeah, we need some drivers for boot camp that have battery saving features. :-/ -
I have a 17 inch MBP, and at quarter brightness + MSN + Fire Fox on wireless, muted volume I get 5 hours of life... and I'm at about 40 cycles. Call Apple and demand a new battery, because that is not normal, unless you're running Vista.

Wow... 5 hours on that? Jeez... my coworkers 15" MBP (just over a month old) is at 40 cycles and his total life is down about 10% already.

my battery is at about 96%, but it keeps wanting to go back to 97% because it's not calibrated. I'm gussing 97% is the accurate level it's at.
Bad battery life
