I bought a ~~Dualshock~~ Dualsense because of the trackpad, didn't realize it didn't have replaceable batteries.
Battery life is bad and it really annoys me.
I think I'll try again to fix the stick drift on my Xbox controller...

Batteries and lack of audio are my only gripes with the steam controller. I still think it's better than every other controller, but I wish it had those. At least though, valve said it will be easy to disassemble with a screwdriver, so we will have a way to replace the battery with an after market one when it dies.

I'm not aware of any controller that can charge NiMH batteries tho. I think the hardware for that would weight as much as the entire controller. Also NiMH batteries don't do well with continuous charging via dock, unlike lithium batteries.

It is a weird flip. My current steam controllers take AA batteries, but my current VR controllers are rechargeable lithium.

Yep. This is why I still only use XBOX controllers.

Big fan of controllers that get all their power from cables. Fuck Batteries! Though I can see how that's quite inconvenient when you're playing on a couch instead of in front of a desk like me.

All my Xbox360 controllers still work fine, but none of my PS3’ Dualshock 3s

Batteries for PS3 Dualshock are still available on ebay in my country. You just unplug a cable and remove a couple of screws. AA are not worth it.

AA should only used for flashlights (emergency), kids toys (safety) or when you are far away from an electricity network for much time (days, weeks).
