Why my iPhone XR randomly making buzzing sounds while charging?

One time when i was charging my iPhone (XR) via cable, it randomly stopped charging out of nowhere, I tried to replug it in, use another charger, clean the dirt inside the port and use another outlet, the accessories were fine except for my phone charging port, So I ended up using an induction charger, just 2 days of using it, My phone was making random buzzing sounds when I left it there to charge, I didn't know what was the cause or issue relating to that situation, can someone help me?
