Hello fredfrommccormick,

Welcome to Apple Support Communities. It sounds like you're having trouble with your iPhone making sounds while charging. I'd be happy to share information that may help.

Is the sound you're hearing the same sound you hear when you connect your iPhone to the charger? If so, try using a different Lightning cable or wall adapter. You may also want to check for any debris in the charging port. You can find more details here: If your iPhone, iPad, or iPod touch won't charge

When you charge wirelessly, try removing the case to see if that makes any difference: How to wirelessly charge your iPhone.

Another step to take is to restart your iPhone: Restart your iPhone.

Take care.
