Hi guys, I purchased the new Macbook Pro, 15" model in december last year and have been using the widget istat pro to monitor the condition of my battery. I noticed when i installed istat pro that my battery life was on 96% about a week ago. Last night I left my MBP in the dormant mode (as in just shutting the lid) and for some reason the power cable had come out. When I woke this morning I discovered that the power cable was out and subsequently plugged the charger back in. When i brought up the istat's widget I noticed something very strange, my battery health had diminished to 68% overnight from 96%. I am wondering how this is possible and if this is anything to be concerned about and if this is a problem whether it will be replaced by Apple warranty. What do you guys think?? Update: I also used another program called Battery Health Monitor with the same results, the charge cycles is 37, so the battery hasn't been used too frequently.
