I know how to screenshot, I just didn't want my document or other open windows to show.
this is what i am getting too just surfing web

@Appledreamer & the OP:
100 % charge means that the OS cannot estimate the remaining running time. Try the same with a 80 % or 50 % charge.
The new MBA should last 12 hours under "normal" use, whatever Apple defines as normal. If you do everything possible to save energy (lowest screen brightness, WiFi off, Bluetooth off, no apps wasting energy, nothing reading/writing SSD), you should get more than that. If you are typing a document, and spend twenty seconds thinking about what to type next, that kind of number shouldn't be unusual. (Just checked: The battery time changes very slowly, so not typing for 20 seconds won't make a difference, but doing very little for 20 minutes will).
Interesting results. Thanks Neeyul & Appledreamer. So 12 h should be no problem for light office work.
Impressive!
Guys, we need more information for battery tests. What's your screen brightness setting at? I see WiFi is on and bluetooth is off. Anything else to note?
screen is 6 clicks off the highest, key board light on two clicks from lowest, blue tooth off, wifi on, 2 tabs open in safari, mail open, i message open, few other small apps.
90% battery

Mine was about half brightness and about the same key backlight, though now I've reduced the backlight to about three notches above off for daytime work. 2-3 Chrome tabs up, iTunes going, Mail app open, MS Word open.
12h for this kind of light use is no problem for these!

I think people are getting OCD over battery life. We are at the point where battery life outlasts most humans for a full day of use (unless that particular human has no life at all outside of the internet). Stop fretting and just enjoy the thing.
It reminds me when I bought my first Prius in 2006. Instead of just enjoying the fact that 75% of their fuel bill evaporated... new Prius owners were driving around barefoot to feel the accelerator better... and improve their milage by 0.1%.

Jim, did you get a new MBA yet? I know you have an 11" but have you purchased the new 2013 model? if yes..what config?
How are you getting that much life out of a machine that's supposed to have around 7 hours? Just wondering
----------
Just to add, imagine how long the 2013 MBAs will run with Mavericks installed! My Air gained a lot of battery life when I installed Mavericks.
If that does not show the inefficiency of the previous (Mac) OS X generations...
indeed

I use CoolBook and keep brightness down to 3rd bar. Note, this shot was taken coming out of standby, so I'm joking around a little bit. But this machine will actually get over 10+ hours, as verified by Anand.
My battery is at 78% showing 18+ hours of life left just reading the forums and chatting with a friend via google talk.. Base model 13" on the original charge straight out of the box.. I don't expect that to be of any accuracy but pretty neat to see it "thinks" it can go that long with this kind of usage. Haswell, then Broadwell is going to turn the tables on computer battery life.. It's about time laptops can compete and out-last tablets these days.

I thought Coolbook didn't support the newest Intel CPUs and Lion and onwards.
