OS X 10.8.1 May Address Mountain Lion Battery Life Issues

The thing I really don't get with battery issues and Apple is that they know their own hardware. It's not like they're programming for thousands of variations of laptops. They have their current lineup and the last say 4 years of hardware variations. THat's substantially smaller than the PC market has to offer. So why would there be any issues to begin with. I know not every piece of application is bullet proof but if you're developing the OS and managing the specific hardware, the chance of stuff like this would be slim to none.
If you live in an area without a bloody Mcdonalds with a hotspot, chances are you also live in an area without 4G LTE
Its not a hardware error, there are so many threads about the issue at Apple Support Communities.
My new MacBook (13 inch) came with ML installed, and battery life shows 9.5 hours.. and runs, not only not hot, not warm, but COOL to the touch
I ordered it built with SSD

It's a joke which implies the only "fix" Apple would implement is to display double the actual battery level.
I have almost exactly the same MBP's early 2011 13''. On the first one is SL and on the other is ML. When SL is corporate laptop and ML is home laptop. When I boot up SL it runs with 50 processes and around 200 threads. when i boot up ML it uses twice as much resources - almost 100 process and 400 threads. I would say that iCloud and all other features added in Lion and Mountain Lion are making hard to imagine 7+ hour battery life like we enjoyed in Snow Leopard. I would really like to see more optimizations and better battery life but i don't think that we'll see that. I'm trying to stay positive and hope that battery life would get better like we got in Snow Leopard.

Good. I've been finding that I need to charge my computer (see signature) sometimes more than once each day.
Maybe you shouldn't update the day it's released...
iOS 5 released... filled with glitches
iOS Lion released... filled with glitches
Any new release... filled with glitches
Patience. Wait a month. Problem resolved.

rMBP, sitting on the train using free wifi right now and i have 3:46 with 94% battery, brightness down to %50 and all i'm doing is browsing macrumors

I also have a 2011 MBP13 and am experiencing the same battery/heat/fan issues when booting up (90 - 95 degrees). I was previously running snow leopard and skipped Lion altogether. As far as a I can tell, our current specs are on par with the entry level macbook pros and airs.
I don't think it's the dynamic video switching, because it happens on my 13" mid-2012 MBP which only has the integrated HD4000, so I'm stuck with this freezing.
I started a discussion over a month ago. Evidence suggests an issue with the HD4000 itself, or the current drivers.

Maybe the freeze happens because the HD4000 starts sending the system corrupt data after it, or the surrounding parts, gets too hot (it has run for short periods above 105C). I have TemperatureMonitor installed, any time the GPU gets above 80°C it's almost guaranteed to freeze. I can't even finish an initial Time Machine backup; the progress window seems to stress the GPU enough to push it above 80°C.
Extremely frustrating, I can't do *anything* on it right now that I couldn't already do on my 2006 Macbook. One less, actually--my old MB might encode video much slower, but it can actually finish the job.
The battery life on my Retina Macbook Pro is great. No issues for me. We have a bunch in the labs at work and they don't show any issues either. I don't doubt there are issues. But, for the amount of machines I have, I'm surprised I'm not seeing it at all.
What version of Flash do you have installed? the latest is 11.4.402.265. Was it a clean install or an upgrade? have you installed all the latest firmware upgrades? what model Mac do you have? the reason why I ask is that (the hardware specifications are in my signature) these problems haven't appeared on either my iMac or MacBook Pro but I have noticed some artifacts when it comes to websites using CSS and other hardware accelerated things that Safari now does - those problems don't occur in non-hardware accelerated browsers such as Firefox.
As for my battery life - I haven't had any problems but I wonder whether it has to do with the drivers and whether they're aggressively scaling the clock speed down enough? It would be interesting to see whether it is a nvidia driver related problem or something shared thus something that is lower level that both drivers share.

My rMBP barely lasts an hour and half
Got 11 hours on mine yesterday... Get gfxcardstatus and set it to use integrated graphics only.

It's a common 100% CPU use from a bad process. Hope they fix it with this update. The process monitor can identify the process and terminate it to get your 5 hours back.
