    Before anyone says anything or provides links I have poked around quite a bit. I'm still unsure if I have a problem warranting Apple's intervention.

    Since new, my MBA has been "leaking" about 1 to 1.5% battery per hour that it's in sleep mode. For example, I can put it to sleep with a full charge, come back twelve hours later and have 85-88%. I haven't observed enough to pinpoint exactly how much it's losing, but it's within this range.

    I've run console and there's nothing going on while it sleeps...goes to sleep when I close the lid/force it and wakes when I open/activate it. Ran terminal and there's nothing blocking sleep. I also installed "Please Sleep," which didn't seem to help.

    So am I to conclude this is within normal operating parameters or should I give Apple a call?

    It's normal that your Mac may use around 1% charge per hour of sleep. However, after the first hour, it should be going into deep sleep, which should last about 30 days on a charge. It's also possible that your MBA didn't stay in sleep mode the whole time.

    This should answer most, if not all, of your battery questions:

    I've already run console and terminal. The computer does indeed go to sleep and there're no processes interrupting it. However, it seems the machine is not going into deep sleep. It's remaining in "light sleep" and thus burning about a percent an hour.

    This may or may not prove helpful: MBA 11" won't go into standby mode
