I've had my MBP 15 since March, when the Penryns first came out. I used to get 4 hours or so unplugged, but now only get 2 hrs, running the same applications, with wireless on. This seems like a very fast drop. I downloaded Coconut Battery and it says I'm at 98% charge (when the power meter says full), with 95% capacity left, after 51 load cycles. surely 95% capacity should yield a lot more than 2 hrs? As for the 98%, is that the maximum it will charge to? Also, how do some people increase their capacity over time, as well as have a computer for several months with only single digit battery load cycles? Finally, for calibration, the macrumors guide says to wait till the battery is fully charged before draining it. Does that mean when the battery meter says "fully charged" or does it mean when it's at 100%... because right now it's "fully charged" but at 98%. Thanks!
