I have been using the Stadia controller plugged into my PC. Since I will always have it plugged in, I removed the battery from the controller so it will not be constantly charging, essentially making it a wired controller. The only problem is, when I turn on the controller without the battery, it works perfectly fine for about 10 seconds, then turns off. Windows 11 instantly recognizes the controller and it seems to retain all functionality, even the rumble. I cannot get the controller to stay on, even with constant controller input. Has anyone ever tried this, or figured out how to make it work?
I would advise to not disassemble the controller to remove the battery, even if everything seems to be working the battery removal may affect some core functionality of the controller (and the controller not staying active may indicate some malfunctioning due to the missing battery)
Hey,
I guess I have to say nice work for removing the battery from the controller. It might have been hard unsoldering the wires without damaging other parts ![]()
May the controller software check battery levels during boot and if no battery is found, it powers off? Maybe attributing the correct voltage levels on battery wires would trick the boot checkup?
Another way would be to monitor the USB power level as laptops may not provide enough power at startup (if power stabilization is reached using a trade off between the battery and USB power).
And last thing I could think of is hacking the controller software but it might be "Mission Impossible" ![]()

I still don't see why you want to remove your battery from your controller except getting it lighter... Nowadays, battery management are quite good in hardware and long term use will not lower your battery capacity as much as it did before!
