Based on the description on their site, the controller includes a built-in battery: "8.39 Wh Li-ion battery, 35+ hours of gameplay... "
That was disappointing for me. Specially condidering the Steam Frame's controllers make use of AA batteries: "One replaceable AA battery per controller, 40hr battery life"
AA Batteries might not be as convenient to use, but being able to replace them is a great advantage. All my Xbox360 controllers still work fine, but none of my PS3' Dualshock 3s.
The official docking station could be used to recharge (rechargables) AA batteries so the functionality could remain the same.
Meanwhile I’m over here bitching about how my DualSense dies after like 8 hours of gameplay while my Xbox Elite Series 2 lasts like 40.
(But both of those are built-in rechargeables.)
yeah, that's my experience. But I just plug in a remote battery and keep going. 0-100% in seconds.
I just keep them on a stand that charges them. Works for any controller with USB-C, I just plug a little dongle into each controller and rest them in the cradle when not in use.
