Android 4.4, codenamed KitKat, was released by Google in 2013 as a major update designed to run smoothly on entry level phones. Its system sounds, including the low battery alert, became familiar to millions of users worldwide during the mid 2010s. As newer Android versions changed the interface, this specific chime was preserved online by soundboard users and editors who associate it with that era of smartphones. It remains popular for retro tech edits, nostalgia posts, and realistic phone scenes.
