Horrible battery life after 10.8.4 update?

Computer: 2010 MacBook Pro 15"

OSx version: 10.8.4

I updated my computer yesterday to OSx 10.8.4.

While I was on 10.8.3 after a startup with nothing running my mac showed 5-7 hours or so of battery life.

With 10.8.4 it now shows 2-3 hours if im lucky after a startup with nothing running.

As I post this I started at 100%, I have been using my computer for not even 20 min now and its down to 80%

The computer shows the battery condition is normal, and my energy saver settings are optimized with graphic swithcing, hard disk sleep, etc..

Any help will be GREATLY appreciated. Thanks!

MacBook Pro, OS X Mountain Lion (10.8.4)

I have the same battery issue as everyone else after the 10.8.4 update..

I have already reinstalled ML and made no difference. My energy settings are where they should be.

Has anyone tried to restore their computer back to an older backup?

I'm about to do that tonight but wanted to find out if that has worked or not.

i downgraded from 10.8 back to 10.7, the battery life has gotten better but i swear it was still not as good as before i upgraded to 10.8

i got about 7+ hr using 10.7.4 before upgraded to 10.8. now i get about 5-6+ after i downgraded from 10.8 to 10.7.5

i think 10.8 somehow trashed something which does not make any sense to me. i am curious if others experience the same after downgrading back to 10.7.x

Just did a fresh install of mountain lion 10.8.5, that seems to have sorted out my battery issues which included lifespan shortening at an alarming rate and very short run time.

Has anyone seen better battery life after yesterday's SMC update? I haven't had a chance to do a full test, but I'll have some results in a few days.

Apple released MacBook Air SMC update 1.9, along with MacBook Pro SMC Firmware update 1.8 and Retina MacBook Pro SMC update 1.1. to address an issue that causes the battery to unexpectedly stop functioning.

Sorry for the late post.

In my tests I've only seen a small improvement of about a half hour. That has been while running 7 programs (iTunes, iMessage, Email, Safari, Google Chrome, uTorrent, Twitter). Otherwise, pretty much the same terrible battery life.

I'm hoping that Mavericks will help correct this. If anyone sees a big change with the new OS please post. I feel as if we are alone on this.
