This sound is commonly identified online as the iOS 5 charging chime, a short device notification tied to older mobile software from the early smartphone era. It spread through meme pages, ringtone uploads, and short-form video edits because many listeners instantly associate it with plugging in a phone. Creators still use it as a quick audio cue for charging, power returning, or retro tech nostalgia. Its staying power comes from how brief, recognizable, and easy to sync it is in visual jokes.
