There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.Still very annoyed that my 2011 13" MBA with ML battery drains so unbelievable fast.
I was seriously at 70% about 15min ago just browsing the forums and i'm already at 63%

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
I challenge that. Your battery life dropped because there was an increase in power demands. You simply need to isolate the source of the higher power demand. I've seen too many of these baseless claims that battery life suddenly dropped significantly doing the same thing. Such claims are absolutely false.My battery life went from a 7 hour battery life doing the normal things I do to a 2.5 hour battery life doing the same things.

Wow you sure are quick GGJ!
OP, as GGJ pointed out, there are many factors that influence the battery life of the MBA. I also have a 13in MBA and have no problems getting ~7.5hrs on a charge.
Some factors to think about:
-Do you have bluetooth on?
-Do you have screen set to max brightness?
-Do you have a strong wifi signal or does your computer have to search for a stronger signal?
-Do you frequent websites with a lot of flash?
-Do you download a lot of files while surfing?
There are many factors that go into how long your battery will last.

Bingo. Had a similar issue, ended up being a printer software eating CPU cycles like a MoFo.
Exactly. It's not the OS itself. It's most likely an app or process that is consuming system resources and drawing more power. You just need to troubleshoot to find what it is.MBA 13" 2011. Bluetooth off, located about 5 feet from the router, no downloading while surfing. I do have the screen set to max brightness.
I got 6-7 hours when I first bought it. Now I'm lucky to get 3 hours with ML. The battery itself seems to be in good shape. Coconut Battery says 43 cycles and 93% capacity remaining. Sure looks software related to me.
No, I'm not implying that. There have been cases of defective batteries, although such cases represent a very small fraction of Mac notebooks. It's also not the user's fault. It's a matter that something is drawing more power, causing shorter battery life. Rather than blame the OS, it takes a bit of troubleshooting to isolate the issue, which is almost always a case of settings or apps running that the user wasn't aware of. Blindly accusing or defending Apple or the OS isn't going to solve the problem. Launching Activity Monitor and gathering facts is a more prudent approach.Are you implying that no matter what,Apple can make no mistake(Bad battery, software glitch..) and it's *always* the user's fault? How about giving someone the benefit of doubt?
This is a good example of what I'm talking about. There was a specific process that was running amok. Once that is identified and corrected, battery life should return to normal.There's a Mountain Lion bug that has Dock running at over 100% cpu. When I hear or see the fans running up I check activity monitor. That seems to be the culprit for me.

Is Coconut battery correct? When did you buy it? It just seems odd that a year old computer only went through 43 cycles.
It's plugged in most of the time.

OP - There is no "issue" for Apple to "fix." It is entirely dependent on you and your usage of your machine.
How exactly did you verify that you're running the exact same tasks?So when I get 5 hours battery life on average, then update to Mountain Lion and now get 3 hours doing the exact same tasks, it's MY fault?
