3 simple rules:

  • DO NOT leave your charger connected when the battery is charged, even when you go to sleep.

  • DO let it discharge completely, when using it wait till it reaches 0%, when sleeping it leave it alone, when you’ll wake up and you’ll open it, a resume from suspend to disk will greet you. OSX FTW.

  • Monitor it and show off OSX performance counters to your friends (images courtesy of CoconutBattery.app and System Profiler.app)
