Ok, just curious, does anyone else's MBP's battery slowly lose charge over time even though it's plugged in? I've got a 2010 MBP 13". Mine only is ever at 100% right after I have used the battery and just recharged it. then it will slowly lose that charge over time until I unplug it, use the battery enough for it to actually charge the battery when I plug it in. (Oh, and coconut battery has never said it ever had 100% full original battery capacity, best it ever said was 97%).
