When I connect the Xbox controller via bluetooth it has a short connection but then switches off after switching it on again and it does not establish a connection anymore!
Battery empty?
No, 3 different pairs were used that were in the packaging are just 2 days old.
Then unfortunately I can't help, the information is not that extensive… Sorry😢
So maybe the battery is empty, if net you must have dropped it or it got too strong a shock, for example a Knoll. If not look for someone who is familiar with it who will be able to help you
Look there picture what i have inserted
Connect new batteries or cables…
It's a day old… And it works fine with cables
Wait, I've only just read your comment when they're only two days old, you can bring them back, do you have a guarantee?
At ms only the controller was bought new / sealed on ebay
Then you really have to go to someone or, as I said, bring them back and ask
Don't help me do it again… I don't know either… Guarantee? Do you have to send it back!
Ah ok then I really don't know what to do next, sorry if I find something I'll let you know
