I purchased a Rev B rMBP in April, and the battery life was stellar at first; lately, I've noticed that the battery life has plummeted to get about 3 hours of use (the time remaining prediction given when clicking the battery icon is incredibly wrong), and I am not running any intensive apps to try and alleviate the situation (Chrome is probably the most CPU-intensive app I am using at this point). It is really starting to impede my use of the machine, so I need to do something. I've been thinking about doing a fresh install of ML, as I have already tried doing an SMC/PRAM reset (to no avail). Coconut battery says I have only gone through about 130 battery cycles and I still have 97% battery capacity, so going to the Genius Bar would not help. Any thoughts or helpful tips would be welcome.
