The sound comes from Huawei phones and tablets released from 2021 onward, where it serves as the system low battery warning under HarmonyOS. The same alert is also heard on some non-Huawei devices running HarmonyOS, which helped the tone spread beyond a single brand of handset. As short phone sounds became popular clips for edits and soundboards, this chime was shared for its clear meaning, anyone hearing it understands a device is about to shut down without needing any on-screen explanation or dialogue.
About this sound
The short low battery chime from Huawei phones running HarmonyOS since 2021, played when power is running out and often used in tech edits and phone memes.
This is the brief alert tone Huawei devices play when the battery drops to a low level. Lasting just over half a second, it is a clean, descending electronic chime that feels urgent without being harsh. The tone is instantly recognisable to HarmonyOS users because it cuts through other notifications and signals that charging is needed soon. In videos, that same urgency reads as a small moment of panic or failure, making the clip useful for punctuating a device dying, a plan running out of energy, or a character giving up at the worst possible time.
