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.
Disagree. I bought the rechargeable replacement for all my xbox controllers. When those wore out, after years, I just replaced them with another rechargeable. Too Easy. I think you are making a mountain out of a mole hill.
Yes but you could easily replace the battery. Going by the description, it sounds like the battery is going to be internal. Now of course video game controllers have been historically easy to open, but it’s not going to be as easy as simply popping out the battery and popping in a new one like the XBOX.
