Unlike Nintendo and PlayStation, Microsoft is committed to backward compatibility. It's gone so far as to make older games for the Xbox playable on modern consoles like the Xbox One and Xbox Series S/X. However, it appears that Microsoft's goal of updating legacy software has extended to hardware as well.
In a recent announcement, Microsoft confirmed that it is giving Xbox One controllers an update so that they will have features that were previously exclusive to Xbox Series S/X controllers.
How do you update your Xbox One controller?
The coming update will allow Xbox One controllers to "remember one Bluetooth host (e.g., smartphone) and one Xbox Wireless host (eg., Xbox console). This way, you don't have to manually switch between two paired devices. All you need to do is to double-tap the pair button of your Xbox One controller and that's it.
