Ps4 controller lies easily with Mcpe?

I've been playing with Controller Mcpe for 2 days, but I have the problem that it was easy.

May be due to your feelings, the distance between the controller and the console / PC, other devices in the area that emit radio signals in the same frequency range, or in general the electronics between the controller and the receiver… Can be anything.

In this case, one can only say with certainty what is definitely not the cause: namely the weather and the time.
