Every time you charge the battery, it counts as a load cycle, right? 1. If i'm charging my battery at home, and it's not fully charged, and then replug it in once I'm in class, did that just count as two load cycles? 2. If the battery is fully charged; should you unplug the charger, or let it continue to charge while at home, so as not to run down the battery and then waste another cycle. 3. If applecare only replaces batteries up to 300 cycles, that means that my battery is irreplaceable in less than a year? wtf? 4. how do you guys usually charge your batteries to get the best life out of it? I've calibrated it, and have noticed that the battery life got worse??? A note: the charger is plugged in right now, and it's fully charged, but the battery is only at 99%... So i've already lost 1% of my battery life after 2 charges?
