What kind of rechargeable AA batteries do you use? I've tried a lot over the years for wiimotes/other controllers, but the battery life is kinda terrible.
The new steam controller is supposed to have 35 hours of battery life, I seem to remember my rechargeable AA powered controllers only getting like 2-4 hours per charge. They might have gotten 4-6 hours when they were new, but it wasn't much better. Seems like even if the steam controller battery deteriorates to 50% capacity (17.5 hours) that would still be far better than my results with rechargeable AA batteries.
