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.
I’d rather have screws than those clip-in covers that break or having to pry the device open like some brands of devices, ie most of the tech industry. Somewhere in the middle. Quickly being able to replace a battery easily a plus don’t get me wrong, but I don’t want it getting torn up in the process one either extreme. I am ok with it may take several minutes, but not with “can I buff this out” or “where is the tape/glue”.
How about clip in covers that don’t break? I’ve been using my XBone controller for like 7 years, swapping batteries out every week or so, and it still works fine. Running in and out screws definitely will not be nearly as durable, especially if they’re anything like the Steam Deck’s screws.
