I have a 17in 1 GHz PB running 10.3.2 with the battery update. I calibrated the battery and it does charge up to 100%. However, over the course of 3-4 days the percentage slowly drops 1% per day even though I'm running off the AC adapter.
Eventually, the battery reaches 96% and starts charging back up to 100%.
Is this a design feature or something I can fix?
