Microsoft has explained its decision to once again use AA batteries to power the Xbox Series X controller, saying it provides "flexibility" for players. According to Microsoft's Jason Ronald (via Eurogamer), both fan and internal feedback was split on the issue, with half preferring AAs and half preferring a rechargeable internal battery, like those found in Sony's DualShock controllers. Ronald says the decision to stick with AAs as the default power supply ultimately provides players "flexibility," as they can use those or purchase a rechargeable battery pack.
