Need i disconnect the power when play? What is the best practice?
No, you will not hurt it. You can have it plugged in and use it at the same time. Be aware that, if you are using a very graphics intensive game, the iPad probably won't charge. I've got my iPad sitting next to me on my desk, plugged in and streaming music over BT speakers. Best thing ever!
Best practice with a lithium ion battery is to charge it when you need to and, once a month, let it run down until it turns itself off and then charge it completely. This calibrates the battery sensor. If you don't do it, it won't hurt the battery.
