i have a 15" macbook pro that's just about to have its first birthday. over the past month or two i have noticed the battery life rapidly dwindling. when it was new it could go well over 2 hours on stand alone battery power, that slowly dipped down to between an hour to an hour and a half. but recently (in the past week or so) it drains almost immediately. i will charge it fully and as soon as i disconnect the power it says i have abour 15 minutes of battery power, which usually ends up being about 5-10. when i plug the power back in it says i'm at 70-80% charge. i have heard of some other people with a similar problem, although not this severe. anyone have any info? i'm really hoping this is a problem that at worst would be fixed by replacing the battery.
