The new Xbox Series X controller, like its predecessors, will use AA batteries instead of a rechargeable battery that is found in PlayStation’s DualShock controllers.
Xbox partner director Jason Ronald told Eurogamer that the Xbox audience is split nearly evenly when it comes their preference between AA batteries versus a built-in rechargeable battery. Sticking with AA batteries for Xbox Series X is an effort to please both camps, as people can still buy a rechargeable battery pack for the controller, Microsoft said.
"What it comes down to is when actually talking to gamers, it’s kind of polarizing and there is a strong camp that really want AAs," Ronald said. "So just giving flexibility is the way to please both [sets of] people… You can use a rechargeable battery pack and it works just like it does on the Elite, [but] it is a separate thing."
