About this tool
Launches a full-page overlay styled after the low-battery alert phones show, with a dimmed backdrop, a battery icon at your chosen percentage, and two buttons that just dismiss it — nothing actually changes your device's power state. Works on any screen, not just your own — a fun one to leave running on a friend's laptop.
