Xbox Series X controller not able to turn use bluetooth despite new batteries

Hi ViperMagma, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regards to your concern.

The Xbox Wireless Controller that comes with Xbox Series X|S includes a feature that allows for quickly switching between a paired Bluetooth device and an Xbox console. If the controller is connected to a Bluetooth device, double-press the Pair button, and the controller will immediately switch its connection to the last Xbox console it was paired to. Then, to switch back to the paired Bluetooth device, press and hold the Pair button to start pairing mode. The controller will automatically connect to the Bluetooth device you were just using while it also searches for new devices – just in case you want to connect a different Bluetooth device or Xbox. If it doesn’t find a new device nearby in pairing mode, it will remain connected to the previous Bluetooth device.

As of the moment, the said feature is not yet available on Xbox Elite Series 2. But what I always do is make sure that when you turn on your devices such as PC or Laptop, the Bluetooth is turned off then turn the controller on first before turning on the Bluetooth for it to automatically reconnect.

it uses wifi that the xbox has a receiver and sender for, similar to the microsoft pc wireless adapter but obviously built into the console.

no bluetooth at all. there is not a single bluetooth chip in the console, the modern xbox controller connect via wifi to the console or bluetooth to phones and pc if not using the adapter for pc. only the controller has bluetooth and this is basic at best.

Does the Xbox Series X or Series S support Bluetooth? | Windows Central

No Bluetooth for Xbox Series X

The Xbox Series X doesn't have Bluetooth, similarly to the Xbox One, Xbox One S, and Xbox One X. The reason is simple; the Bluetooth signal isn't strong enough to meet Microsoft's specifications for latency. Microsoft uses its proprietary signal, dubbed Xbox Wireless, for connecting controllers and other accessories, like the Turtle Beach Stealth 600 and the SteelSeries 9X wireless headsets.

Microsoft's signal is far stronger than Bluetooth. Since many people typically game while sitting far away from their consoles in the living room or so on, Bluetooth's susceptibility to interference increases exponentially at longer ranges. If you were hoping you could use a USB Bluetooth adapter, it wouldn't work either, as the Xbox Series X and other Xbox One consoles don't have the drivers necessary to power them.

No one knows if the battery will fit the new controller. I would have thought it would. After all, you can play the new controller on the Xbox One and the Series X/S, as you can with the old controller too. So it would be daft not to use the battery from
the old Xbox One controller.

The Series X controllers available now uses the same official battery packs as the Xbox One and Series S controllers.

I am not entirely sure about charging battery, but it will take AA batteries like the current controllers.
