Settings > Sound > Advanced > Charging Sounds
If I uncheck ‘Enable’, it’ll re-enable itself as soon as I leave that screen and go back into it.
Under ‘Notification Sounds’ is ‘Wired Charging’… if I change ‘ChargingStarted’ to ‘None’, it’ll reset to ‘ChargingStarted’ as soon as I leave that screen and go back into it.
