You plug it in when you aren't using it
And what happens when the controller dies? That requires:
- Having a cable nearby
- Being tethered to said cable for an hour.
I don't have a charging station in my couch.
I guarantee you the time spent swapping AAs every few days will far outweigh the time you spend using a screw driver to replace this battery at the frequency it requires.
I guarantee you it doesn't. Not to mention those screws would become stripped in a matter of weeks.
