    Heres my problem, My power brick that plugs into the outlet cracked out, I might have dropped it, but I don't remember but It screwed up my battery pretty badly ( Was turning off randomly at 30% and was working fine at 0% ). I went to apple store and they replaced the battery and charger for me.

    I got home and plugged the battery into charge, checked the life and it said 100% on istat and coconut battery. When I woke up the next morning I checked istat and it said battery life 90%???? I restarted the computer checked coconut and it said 92% life. Weird, for a new battery. I went to the apple store again today and showed them that the new battery was 92% life and they replaced it again.

    It was showing 100% life all day, I get home today...92% again. Is this a new battery thing or is something wrong with my computer?? This battery thing is starting to piss me off? Anyone have any insight on this matter???

    I don't know if this applies for a brand new battery, but have you calibrated it yet? I know with my MBP, my battery health will drop randomly from time to time, yet a calibration seems to make istat/coconut battery happy in terms of my battery health
