How the Low Battery Warning screensaver works
The saver renders a familiar critical-battery warning layout with a slowly draining battery icon.
The percentage ticks down convincingly, with an urgent red glow for extra effect.
Your real device battery is never read or affected — it is a purely visual screensaver.
Press any key or move the mouse to exit, like any other screensaver.
