I picked up an Xbox One the other week and I'm having trouble getting the controller to work with rechargeable AA batteries. These are the same batteries I've used in my Xbox 360 and I've tested it with about 8 different batteries. 4 of which have been on the charger at least a week.
When I put the batteries in and hold the xbox button it lights up, blinks once or twice, then goes blank.
It is nice that there is a Power Statistics gui to indicate battery power of devices now, so I can tell when batteries in my wireless mouse are getting low and it is not a complete surprise when they run down.
