Ps4 controller Wackelkontakt and charging with cable not possible?

I bought a new controller and had it for two days without problems play, and during the week I have him on the PS4 charged until then constantly the wobble contact occurs and I have not seen the loading bar, which was always on a bar or no more. I bought a new Ps4 controller today and it went without problems. Then I got my cable for the PS4 charging station earlier from the buddy, since I had forgotten it. And then I load the new controller and the something broken, and suddenly it has recharged, not on the side where the USB plug comes in but he loads where the headset comes in next to it. Because he does load now but on USB cable, it can't be loaded. Why is it?

Sorry, but your German is so bad… You understand nothing…

Can you read, then read a little slower. Has done anyway now, since he has recharged the night and he works again thanks to the charging station
