Xbox controller cable?

If I don't want to constantly change the batteries, can I simply use the controller via a cable? Or is the cable only there for data transmission?

Yes you can play with the cables connected.

I also recommend the Play and Charge Kit from Microsoft. Is more ecological and economical than constantly using new batteries.

Thanks, the only question was whether I never have to change batteries when I'm just playing over the cable. So similar to headphones that only work with the power of the cell phone. I phrased it a bit clumsily

Of course, the controller only works with a cable.
