hi fellas, i need help , did anyone else encounter this issue. the thing is when i plug the pro controller in the wii u usb port to charge it the charging led is Red and Not Orangeish .. and i've left it 30 minutes charging and it was still red and syncing works and everything on the controller works only when connected to the console cause as soon as i remove the USB the controller turns itself off.. is this a battery issue ? (btw. sidenote i got this controller from a friend and he hasn't used it for quite a long time) should i open it up and remove battery and place it back in or something? basically it looks new and all the buttons work, everything of it works while connected to wii u, but as soon as i remove the controller it turns itself off, should i maybe put it to charge for 5h or so?
