new macbook owner here.. love it! what is a battery cycle? if i charge up the macbook all the way, unplug it, use 15% of the battery life and plug it back in. would this be considered a battery cycle? or do i have to reach a certain/different percentage level? i hope i've been searching in the right area. i'm finding things on calibrating your battery, but nothing that really tells me what apple considers a battery cycle. coconut battery users: why does coconut say that my macbook is 123 months old? a flaw in the software, maybe?
