Q: Battery life dropped considerably on Mountain Lion.

read on Conan Doyle and where he got his methods. nothing he attributed to Holmes was a Conan Doyle creation. Not even the word hypothesis. Like Peirce, Whilliam Merrel's hypotetico-deductive model (1830s) as well as inference created the very language Dole borrowed.

So I take it your answer is no, you don't have any attribution for your simple statement?

Wish Messers Holmes and Watson were here to solve "The Case of the Draining Battery" mystery.

Eliminate the impossible, then deal with the tricky bit.

Would not even try, to do so woul dimply playing your game. When it comes to math, history of math, developpment of logic, there is no argument as to the sequence. Dole does not register in the history of developmment of reasoning as he never contributed to it.  If the words he used existed before him decades earlier, .... therefore.... as per deductive reasoning... will not fill the blancs.

Lie down in a darkened room immediately, help is on the way.

why would one be blocked from reading the " branched to new discussion" link above?

easy way to tell a thread has gotten too long is when unrelated tangents start popping up left and right, but these tangents are quite funny.

my battery fixed itself (again). the variability in the lifespan is great; yesterday, i got 2.5hrs of life (with the battery icon on the menu bar reporting about the same), and today, i got 6.5hrs.  I'm doing the exact same thing i was doing all of yesterday- typing papers, listening to music, and surfing the web.  i tested this batt. life surge by opening multiple tabs, iPhoto, iTunes, Spotify, multiple word documents, notes, reminders, and a bunch of other stuff, and the time estimate wavered by 5 minutes.

i have a genius bar appt set up for tomorrow, but now i'm wondering whether, if this 6.5hr life proceeds, i should still take it in and have them run the diagnostics to tell me why my batt. life is fluctuating so. any (related) thoughts?

So after a few days of reading on Flash, and Hoock vs Adobe CEO, it was clear that Hook was blaming Flash for poor poor mobility performance. Battery drain was one. Online is also full of articles "Flash draining mobile bateries." yesterday i began a test. Unistalled Flash and see... Then this nice girl wanted to chat. And chat of course, needed Flash. Reinstalled. Finally, hours later, was able later to unistall it.

Result? Battery drain dropped. And then, I realized as well, that most pages I opened would have had Flash in some nook or corner.. What I thought photos were all flash as I now get the plugin symbol. Flash was always on. SMC is recalculated times from 4 hrs towards 8 for fulll charge. Am adding one shot to illustrate the change after some heavy usage.

I cannot explain why the other MBA did not have this problem. I do remember waiting a while before installing Flash. no clue whatsoever. It is possible that something else triggers the GPU- for example, as proved before, Preview. But no doubt, some affected units have their GPU firing up. You trigger it and you drop from 7 to4 or, 6 to 3.5.

Anyone reading this, try unistalling Flash, do the PRAM reset, SMC, and then come tell us what you noted. Do not use iPhoto nor Preview. And just wifi surfing.

next test, of course. Turn on Preview.

I wish Flash just went away as the technological bad dream it still is.

I have finally solved this issue on my rMBP by doing a clean install of 10.8 and not updating to 10.8.1.

I had been getting only 2-2.5 hours of battery life previously. I tried resetting PRAM and PMC, and removing the corrupt desktop prefs file, but none of this worked.

So I decided to try a clean install. It appeared to be much better right away with ~9 hour battery ETAs. I then used migration assistant to transfer everything back from Time Machine, so this defintely tells me the issue was 10.8.1 and likely not anything that I had installed or done. Staying on 10.8 for the time being.

Hope this helps some of you still struggling with this issue.

SJ was right about Flash...years ago.  It was only moderate garbage then, but it got progressively worse and is at end-of-life now thank goodness.  Even Adobe stopped developing it for mobile so it's only a matter of time.  I used to develop websites with it back in the Macromedia days, but there are a number of much better, considerably less buggy, more secure non-CPU hoggish alternatives so I stopped years ago.  Unfortunately many of the great unwashed dev masses still insist on using it.  [/rant]

That said, I never added Flash to my late 2010 MBA and it doesn't have a dual GPU setup (and consequently no overheating)...but of course it still incurs the severe battery drain. 

Hurry 10.8.2!!

Fresh installs have helped a few folks here.  However this all stated, at least for almost everyone here, with the initial install of 10.8 Mountain Lion (fresh and upgrade).

10.8.1 actually improved battery life slightly for some of us (me included)...but not for others.

You can have a read through the thread for the various theories as to why this is an issue.

Rumors persist that 10.8.2 will resolve things and it's due out any minute so only time will tell.

Hope your MacBook continues to enjoy the battery life and health advertised!

10.8.2 just dropped.

Installing now on my iMac.

I'm going to do another fresh install of Mountain Lion on my MacBook Air...fingers crossed!

No mention of a battery fix.

edit: wrong post

10.8.2 is 4.37GBs, so a lot of code in there.  FB, Twitter and the rest of it is fine, and Power Nap for my Late 2010 MacBook Air may be nice...but there's only one thing that I really want out of this update!

FWIW Apple released iOS 6 at the same time and downloads are s-l-o-w...slammed servers no doubt.

So far, the 10.8.2 update is only available through the Software Update feature (the App Store).

I will likely wait until the 10.8.2 Combo Updater stand-alone is available (I'm assuming that it will be after a brief delay), and I'll follow the old-fashioned "repair permissions - totally backup the Mac - install the update using the combo updater" sequence. Following that cautious scenario has kept me afloat several times when others were swamped by an unpredictable problem, and since I don't like either treading water or sinking to the bottom, I'll stick with the plan.

Bur, wow! -- I am eager to get it done, ASAP !!!  Gooooo Apple! I am highly optimistic, after reading numerous very upbeat reports from developers-testers of the "golden master" of this update.
