On our iPad it doesn't matter the method that you connect it, it still fails to actually charge (still shows charging). Only way we have gotten ours to charge to 100% is to plug it into a charger and turn it off. After about 10-15hrs the iPad can be turned on again and you are greeted with 100% battery life. Any sooner than that and it will show less than 100%.
