Hey guys quick question: I bought my 2011 MBA shortly after they were released, I think I got it around November. Since then I've used my MBA entirely for school, taking it with me daily and usually using it constantly, bringing it home with a charge usually in the range of 30-40%. On occasion it dips down below that and once or twice it has gone to the "reserve power" warning. My battery health (iStat Pro and Coconut Battery) show that I'm at 90% with 235 cycles. My understanding was that Apple ensures 1000 cycles before 80% health and that past 300 cycles the battery isn't covered under applecare anymore? Is that correct? Why is my health so low then? At this rate I'll reach 80% before 500 cycles... Side note: anyone know how I can get a copy of my receipt of purchase for my mba? I bought it in store and had the paper receipt when it was shipped to me but I've since lost it (moved twice since then).
