Gone are the days where you have to open up a menu on screen to then having to press a tiny red button on the controller to sync them with the console. The back of the packaging for the Nintendo Switch Pro Controller shows that by plugging it into the Nintendo Switch console via USB, the controller will automatically sync. Pressing the sync button on the controller will also do the trick but it’s good to know that this isn’t the only option.
It’s also worth noting that the packaging also states that the lithium battery can last up to 40 hours off a single charge.
