This has probably been asked before. But I got my new MBP today, and I was wondering - whats the best way to care for the battery? Should I let it drain out, and then plug it back up to fully charge? Or have it plugged in when available and only let it run off the battery power when I have to (ie. When I'm away from home)? I had a minor problem with my first MacBook - and that was the life of the battery. I've got around 900 cycles on it now, and that was in the timespan of a couple of years. So, the battery life on my first MB has decreased significantly, which is why I upgraded to the MBP. I'd like to avoid that this time around, if possible? Less cycles = keeping it plugged in more than not. Would that be worse for it?
