No secret tuning guys. I'm not that advanced.

I went through weeks with it between 97% and 100% but I figured if I kept charging it to 100%, leaving it plugged in for a while then using it on battery till it completely turned off then going through that process a few times a week hoping it would get better. I've not seen many macbook pros at 100% when they ship and are charged but my friends blacbook is always 100%. Now I can say mine is too. Care to share your battery stats with us? I advise you both to do what I've done for a few weeks and see if you notice an improvement if you don't already do that, that is. Note that I've never interrupted a charge, the MBP is either charging to 100% before I take the power out or it's being used down from 100% on battery. I'm very pertinacity and precise on the use of it since it's first charge.
There is no reason why your MBP's can't be 100% health and excellent battery life since it's all about the care you take of them since they're naturally good quality batteries.
