Sure, I was actually referring to the whole "calibrate" process. My point was simply that I don't even like to risk the idea of running out of battery.
I'm a polite dude haha. I don't cause scenes. I have no sense of entitlement other than believing that if part of the computer is deemed defective, and I have apple care, it should be replaced. Of course, anyone is entitled to what they paid for with an extended warranty.
Btw, the store ran the battery diagnostic and the battery indeed came back as defective. They have to submit the report to Apple, who then reviews it and decides if they will mail a new battery. They mentioned something like batteries only being covered for a year, even under Apple Care, which I haven't heard before. In which case I would have to buy the battery, but "labor" of installation would be covered by Apple Care. I'm guessing Apple will send a new battery, but we'll find out soon!
