Hi folks!


I noticed that even though my battery is fully charged it only gives me about 4 hours of battery life sometimes. I have a MacBook Pro early 2011 i3 13". Some days I'm able to go up to 6 hours but  sometimes it goes down to 4.5 hours even withou any applications running. I occasionally calibrate my battery as well but I'm wondering why. I remember the power disconnecting for a second before this happened. So maybe if I run the battery down fully and charge it again it should give a the proper readings again or a recalibration is necessary? Btw, my battery have just about 150 cycles on it..

Logic Pro, Mac OS X (10.6.8)
