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?
