This alert came from generic and budget smartphones built on Mediatek chipsets that shipped with Android versions 2.3 through 4.4, covering the Gingerbread to KitKat era. Unlike branded ringtones, this default warning was shared across many unbranded devices, so millions heard the same beep. Clips of it later circulated on soundboards alongside other system tones like a discord notification or a ding sound effect. It remains popular because it instantly communicates low power without explanation, and for many users it recalls their first smartphone.
