    Mine had 91% when it was first opened.

    When should I do the first recharge? 10%? 0%? or any time?

    You should let it drain to 0% first, then charge it up.

    Charge it up to 100% first at its current state, then let it drain all the way through continuous use. (Can leave your display always on)

    Ummmm, just use it until whenever, and plug it in when it gets low or you go to bed...

    It is not a NiCd or NiMH battery, both of which had memory problems and responded better to those type of treatments. Just charge it whenever you are ready. My ipad1 is 2 years old, I have always charged the battery whenever I wanted to, and it still has 7 hours of battery life.

    You battery will still be going strong when you are ready to buy the iPad5.

    The only caveat to all that is that the battery management software on the iPad needs a complete discharge cycle periodically to calibrate the "percentage discharge" numbers. Lack of calibration will not affect how long the battery lasts, but either the device may shut down above 2% at some point, or will say you are at 2% when there is plenty of time left on your battery. The iPad shutdown is triggered by low battery voltage rather the calculated "percent discharged".

    this is a lithium polymer battery. you dont need to drain it to keep a charge anymore. That was the ni-cd that needed that

    "For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down)."

    From apple's page linked above.

    Use it thru out the day.

    Then plug it in to charge before you go to sleep tonight.

    Really people, it's not Rocket Science.
