First off, I'm running an original MBP 15" 2.16 Ghz core duo. It's about a year old this month. The issue I'm having is that my battery life is only keeping a charge for roughly 1 hour or less, istat is showing my battery health ranging from 30%-40% with 133 cycles. Just last week I was getting a good 2 and a half hours. I calibrated my battery last night and it is showing me 1hr of battery life still. i just want to know if people with the same computer are seeing the same battery life span or are they getting better. Also, are there any suggestions on what I can do to get back my juice??
