Place it at the point where the cable connects in a phone or tech edit, after any low-battery moment and before the screen lights up. Follow it with a bell ding to mark the phone as ready, then let the scene move on to the next shot.
About this sound
This is the brief electronic chime a Samsung Galaxy S25 plays when a 15W charger connects, lasting just over a second. The tone is soft and clean, giving a small sense of reassurance that power is flowing. It feels calm and familiar, like the quiet confirmation you expect when plugging a phone in at night.
