So ever since I've got my uMBP at the beginning of June, I have been using coconutBattery to check my battery life and what not. Recently it has dipped below the 5450 mAh under a month. I take it out occasionally and when I do take it out it's to my girlfriend's house to watch some videos that I have on my HD. As it stands my coconutBattery is reading 4912 mAh. This is worrysome and considerably lower for a uMBP that's barely 2 months old. I've calibrated the battery twice. Once when I first got it and once yesterday before I slept. I'm thinking of bringing it to Apple, but I bought my uMBP at FS. I know that I still have my AppleCare does this cover it? I mean I feel as though as it should considering the fact that it's clearly not the user's fault? Any advice is appreciated as I'm planning to have this issue resolved by tonight. Oh another thing, if it is a defective battery will they be opening my baby up? I have babied my laptop since day 1 and don't want it to be opened up already. I mean It's not the same! Will they provide a new uMBP or will they just change the battery? I'm really concerned considering the fact I haven't even started school and I will be lugging my uMBP around campus when my project is not to be done in the Labs for HW. (I'm taking a New Media and Web Development Course) Thanks!
