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.


Vastly prefer my DualSense with built-in rechargeable that lasts multiple days unplugged over my Xbox Series pad that eats AAs. Just make the replacement simple and affordable, which it appears they will.
I have the exact opposite experience: the NiMH rechargeables in my Xbox Series controller lasted ages (before I replaced them with a play-and-charge pack that uses the controller’s port to charge and also lasts forever), while the DualSense dies in like 10 hours of play.
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.
