Your phone’s battery can drain quickly while gaming, especially with all the graphics processing, networking, and audio involved. That’s why we’ve designed a pass-through charging port on our Backbone controllers that lets you charge your phone while playing. This way, you can play longer sessions without worrying about getting that "Low Battery" notification. With your charging cable connected to a power source, just plug the other end into the port on the bottom of the controller and you're all set!
