iPhone 12 Pro Static Noises

Alright guys, these forums have always been so helpful for me but today I created an account because I am extremely creeped out by my device. When charging the phone has a static sound coming from it as well as beeping. VERY VERY faint but my hearing sensitive and I could’ve sworn I accidentally left music playing. Anyone else having this issue?? Already erased and set up as new! Still happening. Old device does not do this. Very creeped out.
