Hi everyone. I've had my MacBook since late May and calibrated it twice (using the steps on apple's site). It seems like after each calibration, the battery "health" gets slightly worse. According to coconut battery and iStat pro, after the first callibration the overall capacity dropped from 5059 mAh to 5004 mAh (99%). Then it rose a little to 5013 mAh over time, and eventually rose again to 5026, then dropped back to 99%. Now, after the second calibration it's dropped to 98% at 4968 mAh. Sorry if that didn't make sense . The point is that the battery was at 100% until after first calibration when it dropped to 99%, now after the second it's dropped to 98%. I know 2% isn't much to fuss about, but will it keep dropping after each calibration, even though the point is to extend battery life? In 4 or 5 months I've only gone through 5 battery cycles (including two calibrations). I leave it plugged in most of the time, perhaps running on battery power until it's at about 80% and then plugging back in. Is there something I should do, or keep using it as normal? It's still kind of new, so I don't want the battery to die suddenly. Thanks (also, while on the subject of batteries, my iPod's having issues. I'd appreciate someone taking a look at http://discussions.apple.com/thread.jspa?threadID=1591184&tstart=0 ).
