Ok I have my whole Unibody macbook replaced last week and I noticed a significant drop in battery life ( I assumed as I hadn't run it in yet). Charging time was 2 hours which was way shorter than normal. However, the battery stats (on power profiler) seem fine. However now my charge is showing 0. Under system profiler maH shows 0 and yet the machine is still on and has been on for last ten mins. In fact it has only just gone off! Is this a duff battery and time to go to apple store?
