I found that my iPad might be half charged after a few hours by USB from PC... too bad I can't find the wall adapter... but when I turn it on, it says "Not charging" without saying the Percentage it already has charged up. Can it show somehow? Maybe by tapping the "Not charging" message but I don't really need to see it so many times. (but tapping doesn't work)
Does the iPad 2 also have the same issue of slow charging too?
