Apple has kept its default iOS charging chime virtually untouchable within standard device settings. While users can freely assign custom ringtones, text tones, and calendar alerts, the system audio tied to power delivery remains locked behind Apple's system partition. The workaround bypasses system audio menus entirely by leaning on background event listeners.
The method relies on the Apple Shortcuts app, specifically its background workflow engine known as Personal Automation. Apple introduced automated event triggers with iOS 14, granting the operating system permission to execute programmatic actions whenever specific hardware states occur. The Connect to power trigger acts as an instant listener. When current enters the lightning or USB-C port, iOS queries the Shortcuts engine, which immediately executes an action pipeline.
Instead of overwriting Apple's internal system files, the automation superimposes audio over the default hardware chime. With the introduction of the Run Without Asking toggle in subsequent iOS updates, Apple removed the requirement for user confirmation before executing background tasks. That single change turned an awkward manual prompt into an instantaneous acoustic gag.
