Calibrateing iPad battery

[tazz3]

I read on a few ipad forums that the battery should be calibrated once a month.
or every other month. i have not done this yet. my battery is about 22 percent how low should i let it go before i recharge it to 10 percent or under 10 percent or is this calibrating bull.
thanks all

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).
