New Air. Closed the lid last night with 72% battery, opened it this morning with 33%.

The battery life when I first purchased was not as good as after approx. 1 week. After reading many threads about battery life I have come to the belief that the computer is doing what it does and that takes about a week. Yesterday was the first time I really had an opportunity to test battery % while unplugged, on and closed for an extended period of time. I unplugged about 9am and reopened approx. 9pm. The computer, to the best of my knowledge, was never opened. It was in my back pack then seat pocket then hotel room. When I reopened it read 100%. My daughters 2010, formally mine, was also still at 100% under identical conditions.
I would give at least 7 days before I would consider returning it for another. Possibly longer if you have a lot of files.

& another complexity you can add to that is if you are downloading a lot of torrent files, loading applications etc, all that stuff consumes power and then there's many things that runs in the background and for a new mac user, the whole new environment does become overwhelming at times as there's a learning curve involved in here (especially if you are going to use all the worth paid for cool applications) & it has been repeatedly proven that nETFLIX is a battery killer..INSTANT bad effects (silverlight sucks)..I am on my 16th cycle now, passed my 14 day window and still trying to squeeze out the best bang for the buck...but with the video watching it's hard to measure...
Could you explain exactly what it is that you find 'overwhelming'?
And no offense, but why would you care about what OSX runs in the background and why are you surprised downloading files chews up the battery?
Well, there's a lot of learning curve involved in here in terms of learning some new applications i.e. the overwhelming piece (for example: explain the difference between xtrafinder and totalfinder and why would u use both?), The programs that OSX runs in background determines the battery consumption. I am not talking about the standard background programs but specific programs that i have installed: for example: Little Snitch !
Downloading files from internet, well i thought that it should be a normal procedure in which SSD is getting filled up with information and wi-fi is getting extensively used along with info pull from the network, so we have a battery impact

You're joking, right?
It takes power to write to the SSD and to pull information from the network. Where else would it come from but the battery?
def something not right. i was on 89% charge, closed lid, went to spain for 8 days came home and it was on 74%, i got home monday and this is tuesday and i still havent charged it. 27% been using it all last night and tonight.

Similar thing happened to me
Was moving some files to my external HD last night from my 2013 Air (11" i5 8GB 256GB). I remember being impressed that the battery was 98% after doing a fair amount of transferring.
When I woke up this morning, my battery was at 63% when I opened the lid. I did leave the external HD plugged in, but the drive turned off when I closed the lid. Power nap is disabled and the computer was not connected to the internet.
It seems that the external HD has to be the culprit, but that seems odd to me considering it wasn't receiving power (well, at least the power light wasn't on). Just submitting my own experience to empathize with OP.

This seems to have resolved itself, or at the very least it hasn't happened like this again. I'm still only getting about 8 hours of battery life when using mostly safari (no flash install) and mail, but considering that's leaps and bounds better than what I was getting before, I'm sort of fine with that. Hopefully it will also resolve itself soon.
