Place it at the start of a power-up sequence, after a low-battery warning and before the device comes alive on screen. Follow it with a bell ding when the battery icon fills, or pair it with a classic error sound first when the charger fails to connect.
Über diesen Sound
This is a very short electronic chime from a Samsung Galaxy phone, lasting under a second, that signals a charger has been recognised. It feels clean, quick and reassuring, with a small sense of relief as power returns. It comes from the TouchWiz interface used on older Galaxy smartphones and tablets, so for longtime users it also carries a quiet nostalgia for that earlier Samsung design.
