Xbox One consoles typically charge in three colors: green, blue, and red. This is because the Xbox One uses a standard power outlet and the three colors correspond to the different types of plugs that it accepts. The Xbox One’s charging process starts by connecting to your power outlet and then turning on your console. Once your console is turned on, it will start to charge. The charging process will take about an hour and a half. If you notice that your Xbox One is not charging, make sure that you have plugged it in correctly and that there are no obstructions in between the outlet and the console. If you still cannot charge your Xbox One, please contact Microsoft for assistance.
