Okay, Apple says the batteries in their late 2008 notebooks should hold at least 80% of a charge until it reaches 400 charge cycles. Unless I read that wrong, my battery should be good for another year at least. I got this notebook in February 13th of 2009 and it used to get 4:30 hours a few months ago (with 85/86% health) and for some reason it is now dropping into the mid 60s and shutting down when it shows 29/39 minutes left in the battery. When I plug in the power and turn the computer back in, it still shows 68% left. And yes, I have discharged and recharged this thing at least 5 times in the last week to see if it would help. Sometimes it will go back up to 80 something % health but then after a day of using it plugged in or using just 30 minutes on the battery the thing dives back into either 73% or 60 something. I tried resetting the SMC but it didn't help. School will be VERY difficult if these battery issues keep up. It makes me want to kick Sony in the nads.
