The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries in older Apple notebooks.Thanks for your help, I am trying a calibration
Resetting the SMC can address some issues, but it does not increase battery life.Someone on Experts Exchange suggested I try a " System Mangement Controller reset", is this sound advice for increasing battery life?
I really encourage you to read the Apple Notebook Battery FAQ.
