On tuesday I bought a ps3 controller. I connected it by connecting it to the usb port cord charger thing to the play station. I charged it until it had three bars, then when i used it, i kept getting a pop up message in the top right corner saying the battery was low. But when i pressed the ps button it said that it was on 3 bars. This has happened many times and now I don't know what to do. How do I get rid of the annoying message or just make the controller have good battery?
