Reports of XBox One hardware issues

How are folks battery life doing (those using AA)? I'm on my second pair and the first only lasted about 20 hours or so (this is about the same as the 360). I was under the impression the X1 controllers lasted much longer due to Kinect turning them off in a more timely manner when not actively in use.

Yeah, I just had to replace mine this weekend for the first time. Definitely getting pretty solid battery life from them, though I kind of wish there was an indicator since I think stuff like rumble triggers just stops working when the batteries are low.
