I actually regret creating this thread as the Full Charge Capacity seems meaningless. The thing is, why do they even include the reading if it's inaccurate?
It's a way of getting a general idea of your battery's health, but it shouldn't be taken too literally. If the percentage is somewhere in the 80s, that battery is less healthy than one in the 90s. But you shouldn't be concerned about fluctuations or specific percentages, as they are only estimates. The only thing to watch is if it drops below 80% before 1000 cycles. If that happens, take it to Apple to have them check the battery to see if it's defective.
 
Full Charge Capacity

MBA Mid-2102 13" 1.8 4GB
Full Charge Capacity (mAh): 5867
344 cycles

I am only getting about 2 hours for a full charge. :mad:
 
Mid 2012 MBA
Original = 6700
Current = 5457
Health = 81%
Cycles = 265

I get about 5-6 hours of web browsing or 4 hours of movie watching.
 
Late 2012 13" MBA
Health: 81%
Cycles: 126

The health fluctuates but usually around 81-84%. Pretty terrible, I think it's because I didn't take it off the charger for like 2 months straight last year.

Web-Browsing+Word Processing will still get me 6:30-7 hours of use

With lots of video watching around 4:30 hours

I am in the same boat.

MBA 13'' 2012

Full charge capacity: 5493

That means battery is at 81,9%

Computer is out of warranty, does anybody know if Apple would do something about it? (for free ;))

I'm not sure what you guys are concerned about. This computer is now over a year old. Mine fluctuates between 82%-86%. I'm at 287 cycles on my battery.

I usually get about 6.5-7 hours of usage. I usually have, Safari, Evernote, DropBox (app), Messages, Reminders, Mail, Calendar, SystemPal and some other small utility apps open for extended functionality. Then sometimes I have Xcode, Eclipse or Coda open for development.

I really don't think you guys have any concern. I was at 5663 mAh yesterday and this morning I'm at 5512 mAh but I expect it to climb again when I go to class for the day.
