I reset the Systems Management Controller (SMC) as per the above (you can also find it here at http://support.apple.com/kb/ht3964). I do get a bit higher estimate -- 1h56m at 47% battery. Still, that's a lot lower than what I used to have. I have a 15" MacBook Pro with 2.2GHz Intel Core i7 + 1GB video card that I bought earlier this month. Rumour has it that Adobe Flash has some issues with Lion that keeps the computer at ramped-up mode, and it's running pretty hot still.

So, I made it through 4.5 hours of web browsing before the "save your work" dialogue popped up. Much sooner than normal.
I'm headed over the Genius Bar. I'll let everyone know what they say there.

Same problem here. Early 2011 MBP 2.3GHz i5, 4GB RAM.
before upgrading to lion, 8 hours of battery. After upgrading to lion, I barely have 3 hours (100% battery charged).

Same issues. 15" MBP 2.53 GHz i5, 4 GB RAM. Usually after a full charge I have ~7 hrs of life, now I have less than 5 hrs, down to 2 hrs after one hour of using Word, Chrome, and Mail checking every 15 mins. Resetting the power estimator gave me an extra 20 mins. The best thing about switching to a Mac was the reliable battery life--did I really pay $2k+ for three hours of battery life?

Yea this is really annoying. I was able to get 9 to 10hrs (MBP 13" Core 2 4GB ram) with screen setting on low brightness and just doing some web browsing. Now i get max 6 hours. I am very annoyed and if this is not fixed i will want a refund. No reason for the time to drop 4 hours becasue of this new update.

Same here. Also I did notice that my MBP 13" 2011 i5 is louder... and I am not talking about fans - I can hear some noise from around magsafe port. It is some sort of buzzing processing noise like you would hear on some power adaptors. It is not loud but still not comfortable while using in a quiet room etc. I am sure I did not have this issue with the SL OSX. Did anyone notice same thing or is it just me?
ps. Could this noise be related to power management? I had similar issue with Vaio and I was told that I should disable C3/C6 support in BIOS. it did help a little bit with the noise but battery life went down.

Noticably reduced battery life on mid-2010 13" MBP.
Resetting SMC added but a few minutes.
According to Activity Monitor, no errant process.
Also, running a bit warmer than before.

I have a dozen or more problems with Lion on my MacBook Pro - one I haven't mentioned elsewhere so far is that I left my MBP on but asleep when I went out last night after a full charge. When I came home about three hours later the battery was at 18%.

Hmm...I've been scouring the web about this issue as I just noticed today that my battery life was cut in half it seems.
Googling, I found a little something about Flash Player going crazy process-wise in the background...so I uninstalled it. (I had 3 instances in my App folder? Not running...just 3 different Flash players in my Flash application folder. *.exe files and all?)
I could literally watch the percentage tick away on my battery meter before I uninstalled Flash. Now my battery seemingly operates as it did with Snow Leopard.
I'm very curious if anyone else will experience the same...

I am also having the same issue. Like Matt said I have to clean up some extra applications from Mission Control to get a decent amount of battery life (80% of Snow Leopard's battery life ) . In general I have 5-6 hrs battery life with Snow Leopard but now I have 3 hrs with Lion. Hope to get the long battery life back.

I too am having the same problem on a early 2011 i5 Macbook Pro. I've tried resetting the SMC and if anything its a bit worse. I've been sat waiting to see what happened, it was at 75% registering 5:56hrs which I thought was alright. I loaded up a different website it it dropped to 72% and 3hrs 20 minutes, which is a big drop.
Hopefully Apple will sort it.

Could it be that the original battery life estimates--y'know, the advertisied numbers that helped sway us to purchase our machines, perhaps they were in error and it's the new calculations that are correct. Ugh!

No, it wasn't an error. I used to use my fully charged MBP on battery and it used to last me the whole day with my level of use. Mainly browsing on wifi with intermittent sleep.
now with the same level o fuse I find myself charging the battery again by 5 in the evening it's totally **** off!! Apple could at least come up with a comfort message: "WE'RE AWARE OF THE FLAWS AND WE'LL FIX IT!!!"
