Purchased roughly 2-3 weeks ago. According to CocunotBattery i've had 9 cycles, and current battery capacity is 5029 mAh, original capacity = 5020 mAh. Right now its at 80% (4052 mAh) and it's telling me I have 2.04 hours of battery left. Thats nowhere near the 4.5 hours I'm expected, and I've noticed its running way too hot. CPU A is running at 66 and the Airport Card is at 69, and its been idle for 20 minutes.. btw I bought 3 year AppleCare but I haven't registered it yet... My brightness is on 20-30%, bluetooth off, wifi on.
