Hello! I got my iPad Mini as a gift for Christmas. So, I didn't heard the instructions about the initial charge. My friends say I should drain it, turn it off and then charge it until it's full. (That would be my "initial charge") but I didn't know that before, so what I did, I charged it when my bat was in 4% didn't shut it down and waited until it's 100% is it okay? Do we really need to do that "initial charge" anymore? Because I feel like My battery is not at its best because I haven't done it the first time. Although I did it for my second time charging. Any advices you could give me? Or experiences to share? Anything would be greatly appreciated. Thank you!!
