The new Xbox One controller uses a new wireless protocol that has cut the latency which has reduced the input lag by as much as 20%. In addition when you plug the controller in to the USB port, it shuts the wireless down and turns the controller into a true wired controller.
In addition Microsoft has confirmed that the new controller will last about 30 hours on a single charge and it only takes 3 hours to charge. That is about a 20% increase over the performance of the Xbox One wireless controller.
Should users choose to use the AA batteries rather than purchase the rechargeable Play & Charge Kit, the disposal AA battery performance should be able to extend the life beyond the 30 hours of play time depending on the AA batteries used.
