I have had my macbook pro since the last week in june and, using coconutbattery, i found out that its already down to 93% of its original capacity. This seemed like a pretty fast drop in battery charge. Unfortunatly i think it might be my fault. I keep my mbp in my room and tend to keep it plugged in for about 6 hours a day, but then i usually run it on battery for about 2. I am getting 2:45 min of bat life with airport on, better energy savings selected, and screen brightness at a low level that i can still read. Is this normal? What can i do to keep my bat healthy?
