I recently purchased the new 13" Macbook Pro on Tuesday. I have been using it a lot but I still feel that the battery is draining way too quickly. I've already calibrated the battery as well as charged twice more since first buying it. I downloaded Coconut Battery and my current battery capacity is 5326 out of 5450 (actually, since I've typed this it went down to 5297). I charged it a few hours ago and it's at 51% at the moment but going down pretty quickly. I may just be a paranoid Mac user since it's my first ever Mac and I've been pretty anal when it comes to Mac. Is it normal? Any suggestions?
