There is a lot going on in the background after you do the upgrade. Spotlight also needs to pretty much re-index your entire drive. Give it a day or two. You can also just leave it sitting on for a while so it can do its thing.

I really want to believe that, but i didn't have very much information on my hard drive to begin with, less than 400 photos, less than 50 documents and just over 2000 songs, i find it hard to beleive that there is that much information to process. I will give it a day to see how it works, but i'm very nervous about this battery having issues when i start college this fall.

I think this issue is coming up enough people need to keep posting so Apple sees it all to address it. And post on websites dealing with Lion reviews/news and issues so everyone knows this is an issue occurring for more than a few.

Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
If you have a TimeMachine drive, update it and disconnect for the duration of this restore time. It will be your second backup system and will have to be wiped and setup again after successfully going back to Snow Leopard if it was connected to the OS X 10.7 boot drive. If it wasn't, then leave it disconnected without updating to Lion. (note: I'm not a TimeMachine user, so I don't know how to restore 10.6 from this medium)
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same name as before, and click Erase...
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly receommended.
A lot of people use a Carbon Copy Clone of their boot drive to a HFS+Journaled external drive as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

I just called Apple support and they talked me through resetting the power manager, the battery now seems to be fine. I can give you the steps the gentleman over the phone gave me, it might just help.
1. Turn off the computer.
2. Hold down Ctrl+Option+shift
3. While holding down these button, press and hold the power button as well.
4. Hold all buttons for at least ten seconds.
5. power back on the computer.
For me that worked, i don't know how it will work for everyone else but immediately my power estimation jumped up to around 9:30 and 10 hours. Which is two hours more than i started with.

Thank you for the info. I tried this and when I turned the MBP back on the time read 7+ hrs, then in less than 3 minutes it read 5+ hrs, the a few minutes it read 9+hrs then 8 then 9 then 10 all within less than 5 minutes. WOW

I've noticed that the battery life estimate dips if it refreshes while i post things on the internet or while mail is loading and then jumps back up, i'm assming it's just calculating in the high wireless usage at that moment. as long as it reads within an hour (or significantly higher) of what you were getting before on a full charge 80% of the time, i wouldn't be too concerned.

Same problem here with MacBook Pro 13 i5 4gb RAM. This is one of the reasons I bought a mac - battery. Incredible really. Probably I'll switch back to Snow Leopard. At least that one seem to work fine for all my needs. Didn't think about this problem before.
8h of battery turned now into 2.

Thanks Phangirloftheopera, that fixed it!

Thanks! This seems to be the thing that worked for me also.

Sadly this works for the first 2 minutes. After that the time is cut in half (and I didn't do anything else other than watching the estimation). Hope they will fix it.

Yep same here. Worked for about 2 minutes. Battery life was up over 5 hours at 100% charge. Then I clicked around on a few pages in Chrome and it went straight down to 2:18 hours. What's odd is when I opened a page with a youtube embedded player thats when the battery life dropped lol.

when you hold on and Hold down Ctrl+Option+shift+power button during 10 secs, what happens on the screen ? or a noise ?

The computer should be shut down when you hold down the buttons, and it should not appear to do anything. When you power it back on the issue should be fixed.
Yesterday my estimated time was jumping around like crazy but i actually let it run out of battery and it did last about seven hours.
