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.


So… is it an obsession to want to be at least <100? Asking for myself. Send help :D
I get consistently better results on steamdeck vs PC due to lower controller latency.
I haven’t tested my controller but I’m pretty sure it’s under 100.
If you want to remove most latency I think the best option is still wired, just get a long cord that reaches easily.
