Android 4.0 Ice Cream Sandwich and the following Jelly Bean updates used this chime as the stock low battery warning on many devices, including Google Nexus models and ZTE phones running near-stock software. As those handsets aged out of daily use, the sound was preserved in recordings, ringtones and soundboard libraries alongside other system alerts like the Discord notification and a simple ding sound effect. It stays in use because modern alerts sound different, so this older tone instantly marks a dying phone and sparks recognition among former owners.
About this sound
The classic Android 4.0 low battery alert from Nexus and ZTE phones, a short two tone warning chime used in tech videos and phone prank edits.
This is the low battery warning chime from Android 4.0 to 4.1.2 as heard on Nexus and ZTE phones. It is a brief, soft two-note electronic alert that repeats the familiar system tone without being harsh or startling. At just over a second long, it instantly signals that a device is about to die. Viewers recognise it immediately from the early smartphone era, so it creates instant tension, nostalgia, or comedy when a character, streamer, or edit pretends a phone is running out of power at the worst possible moment.
