Hey folks, Just got the 13" base model yesterday and it suites my needs very well. I did read about the battery cycles and calibrating the battery, but I still didn't get a clear answer as to when to charge it. Usage: I'll be using this MBP at home most of the time say 8 to 10 hours a day, and might carry it to college occasionally. So these are my questions. 1. Should I keep the power adapter plugged in even if it is fully charged? 2. Or should I charge it fully, then let it completely drain, then charge it again? 3. Will keeping it connected to power all the time save the battery life(cycles)? Thanks in advance. I never really bothered about the battery life much, but on MBP I thought I'll do what is right.
