Seems to me your phone is picking up noise from the power supply, any power supply should eliminate noise via components built in to it so it is possible that there is a failure of noise suppression capacitors.
If you have access to another power supply you can prove beyond doubt where the noise is coming from, if it is still there with a different supply then it is a problem with your phone.
