Hey guys, I just calibrated my battery for the first time yesterday (first time since I bought the laptop in August) and the first thing I noticed was a significant drop in battery life. Normally on a full charge I would get around 5 hours of use and after calibration I was only getting 4 hours so I didn't worry about it. Except today I have had to charge my MBP 3 times and now after a full charge it says I will only get 3:30 hours of charge. That seems like a big drop in one day. Whats going on here?
