This might be strange, but have you ever listened to the sound of your phone's original power adapter? Mine has a faint sound when plugged in, is it normal?

adapter doesnt make a sound.

Obviously it does. If you listen closely to your power brick, you will get sound like you did.

Even i using a Oppo Power Brick, same sound.

Eventually when you disconnect the phone from charging, it stops from fainting sound.
