Sorry for yet another question on battery life, but I wasn't quite sure on how to maximize my battery life. On the one hand, it's supposed to help battery life if I keep the electrons moving. On the other hand, every time I work on battery power it will require that I eventually plug it in, thereby increasing the battery charge 'cycles'. So, I'm trying to understand what the optimal strategy would be: Is it better to run on battery all the time and plug in only to recharge? Or is it better to use the MBP plugged in and consciously run it on battery life one or two times a week?
