In previous threads, we've established that there's no harm in leaving a MacBook Pro plugged in all the time. But now I'm wondering whether it's actually BETTER to do so. My reasoning is that Apple claims the battery to be good for 1,000 cycles. If I'm leaving my MBP plugged in all the time, I'm not using the battery, therefore I'm not using up a charging cycle; whereas if I use the battery to say 75%, charge it back to 100%, using it back down to 75% again, etc.. I'm slowly using up charging cycles. Thoughts?
