CD MBP, 2.16 GHz, 2GB RAM, very early build. Installed Leopard and am (mostly) loving it -- while connected to AC power. When I unplugged, I suddenly noticed I had less than an hour of battery life. A check in System Profiler showed my battery as having 2607 mAh full charge capacity -- before I installed Leopard, it had ~5100 mAh. This is a relatively new battery with 65 cycles on it. The battery works fine -- no sudden shutdown or anything -- but this suddenly lower capacity is very strange. I tried an SMC reset with no effect. Next I'll try calibration. Has anyone experienced this? Causes?
