    The battery level is suppose to discharge to 95 percent if you're continuously connected to power but I don't think it's ever suppose to drop to 40 percent if you're still connected to power. You should try to calibrate the battery and start using your battery more. 8 cycles in 3 months isn't really good for you battery and if you keep the same habit of keeping it connected to power, you'll kill your battery much quicker.

    instructions on how to calibrate your battery can be found directly on the apple website. Just search it and you'll find it. And yes, using your battery more can definitely be beneficial to your battery's health

    Just now. LOL. These days, I find the Battery FAQ gets posted by others in lots of threads I don't see. As long as the information gets out there, it doesn't matter who does it! :)
