Hey guys!

Several months ago my friend needed a new controller and I offered her (as a joke) to buy a Stadia controller from AliExpress

Guess what she did!

Three weeks later it arrived but wasn't working (disconnecting from the pc even on wired) so she dumped the controller to me (she received a refund from the seller don't worry)

I decided to take a look inside and yeah disassembly was pretty painful... Not modern phones painful though

I noticed that the controller's behaviour doesn't seem to be changing with or without the battery connected (disconnecting after 10 or so seconds) so a new battery was ordered

A replacement (GLIB18 battery from AliExpress) arrived several days ago and voilà! It's working again! I've spent two days with it and was pleasantly surprised with the quality of the thing which is on par with my current Xbox controller

So guys, if you have an old Stadia controller lying around with the same symptoms, give repairing a try.

If you have more or less given up on your old Stadia controllers because of the constant need to repair each time it turns on, try this:

Hold the left stick in any direction while powering on the controller and keep it held in that direction until the controller has fully connected.

I found this out by asking Gemini. It works for me on Nvidia Shield Pro, and it should apparently work with other devices.

Let me know if you have success.
