My aimcontroller for the ps4 automatically disconnects what should I do?

Since last night my controller has been going crazy no matter what I do, he logs in briefly and a few seconds later he simply disconnects even though his battery is full and the ps4 has not forgotten him either, so what should I do?

Stop hitting on it

I never hit the controller because it cost just under 400 euro

Then please be ashamed to spend 400 euro for a controller for the price you would have got 8 pieces for the price of 50 euro!

You probably don't even know what an aim controller is

Could it be that the PS button is stuck? Because if the ps button is pressed for 10 seconds, the controller logs off again.
