Does the Xbox controller + USB-C Cable emit radio frequency radiations when connected via...

Hi there Giallo, my name is Gerardo, and I'm an Xbox player, just like you. I'll be happy to assist you with any questions or concerns you may have.

When an Xbox controller is connected to a PC via a USB-C cable, it operates in wired mode, meaning it relies solely on the physical connection through the USB cable for data transmission and power supply. In this mode, the wireless module is generally deactivated, as the controller prioritizes the wired connection, meaning no wireless signals are transmitted or received.

Please keep in mind that in this public forum, we are just fellow players like you, trying to help other players with our best intentions.

I hope this helps and if you have further questions please let me know.

Kind regards,
Gerardo.

Hello JackTDS

Fears surrounding Wi-Fi signal start when you mention the word radiation. While it’s true Wi-Fi does emit radiation, it’s within the radio-frequency (RF) band – a low-energy, non-ionising, non-harmful type.

So no, it's not harmful and you're free to enjoy Xbox and all the amazing benefits it offers!

Hi, it may be that you have some trouble field? Something that also radiates frequencies. You can connect and disconnect your controller briefly via USB to the console, then it is wirelessly connected again

Xbox controllers can buzz using the xbox accesories app on xbox. The controllers can emit radio frequency on the xbox radio line but Im not sure how you can execute that idea. Best thing to do is to buzz it and look around the house!

You should use the following troubleshooting steps to check if the radio in the controller is faulty, or if it's an issue with the batteries in the controller.

So you already say that the controller works, when you connect it directly to the console via USB. Check in the Xbox Accessories app on the console, that the controller has the most up to date firmware.

As Flymonkey102 already said, the controller will turn off it's radio and use the USB cable to send control input to the console instead of the wireless connection.

If the controller is up to date, connect your controller to an USB charger or power bank (take out the batteries first). This will force the controller to use it's wireless radio to send controller input, but lets you power the controller reliably via USB.

If the controller does NOT work when connected to the USB charger, then the controller's radio is defective and you need to send it in for repair via
https://devicesupport.microsoft.com (you need to register your console first if not already done so, then choose that you have an issue with an accessory with that console. Then you can choose the controller).

If the controller is working properly with the USB charger, make sure that your batteries are freshly charged or new. Also keep in mind, that older rechargeable batteries can't get to their full power anymore, even if they were just charged. And since rechargeable
batteries only provide 1.2V instead of 1.5V, it might be that the older rechargeable batteries aren't providing enough power.
