Is OS X Mountain Lion Crippling Laptop Battery Life?
Shortly after OS X Mountain Lion was released, a number of users began posting on Apple Support Communities that their laptops had started experiencing inexplicable battery life issues. Specifically, battery life is being drained exponentially faster with Mountain Lion.
Given the millions of new Lion tamers out there (my pet name for the bazillion people that nabbed Mountain Lion immediately upon its release), the criticisms are loud and growing louder with each passing day.
Most of those reporting the issue say that battery life has dropped by one or two hours. Other cases are more severe, with claims of laptops dying after just two hours of operation with OS X Mountain Lion installed. Making matters worse, hotter machines have even been reported.
Apple is now aware of the issue and is believed to be investigating the matter in hopes of quickly locating and resolving the offending culprit.

I'm having heat and battery problems with my 2011 13-inch MacBook Pro ever since I downloaded and updated. I really hope they fix this in 10.8.1

Well, I installed it on my 27" iMac I noticed a huge difference in temperature. Back with Lion my machine ran hot, even on cold days. Now it runs cool and smooth. I obviously can't report on battery life since it doesn't have one, but I'm pretty happy with Mountain Lion so far.
My guess is that all the iCloud-based apps and push notifications are draining battery in the background.

I've been using 10.8 since the GM release on my Mid 2010 MBP (Upgraded with a Samsung 830 SSD) and haven't had any issues. In fact, I believe the estimated time remaining has become more accurate as it'll say I'm going to have 5 hours of life with Safari/Mail/Messages/Adium/Steam/iTunes and a few other apps open… and Steam isn't particularly friendly on the battery life, I've found.
Closing Steam, it estimates about 6 hours battery life on 97%. Lion wasn't that good, in comparison.

No problem on an early 11 MBP 13"
I did a fresh install thou and its very cool, been using it now for 3hours and still 62% left (4 hours)
I got rid of the default battery indicator and choose to use iStatMenu for battery which shows the remaining time.
