Hey all, So, my MBP was charged this morning, and, AFAIK, had its usual 96%-97% battery health. I used it during one class, while plugged in, and then opened it twice on battery power (once to see if I could connect to the wireless network on campus for about 3 minutes, and once to try and send something on a computer-to-computer network; that time I didn't even enter my password into the "wake from sleep" password dialogue before I closed my MBP). Looking at it (it is now charging up from its roughly 1-2% battery loss from those times and from being asleep for a few hours), the battery health is now 88% (4863 mAh of 5500 mAh, according to both Coconut Battery and Apple System Profiler). I've had it fluctuate before, down to about 92%, when I was using it on battery power a lot and recharging it frequently, but it always bounced back up after a night of being plugged in; as of this morning, I hadn't used it on battery power for about 5 days, and doing so in the past has never caused a problem. I'm going to let it charge and everything overnight, hopefully that'll bring the health back up. Your thoughts?
