The ferrite choke, er, chokes, some types of interference from being transmitted on the cable it is on.
Thus if you've a junky 3rd party power supply it could well be spewing all kinds of noise on the line. Then a choke can help. However if the em noise is coming from within the handset then no, the choke will have no effect.
My advice would be to use the proper charger, from the OEM, and seeing if that makes a difference. If that corrects the problem you'll not only be able to power 'n play but also extend the life of the battery by charging it as it was intended.
