How the Device Vitals Board screensaver works

The saver reads real, live values your browser already exposes: battery level and charging state, network connection type, logical CPU cores, and display resolution.

Metrics update live as they genuinely change — for example, the battery percentage ticks as your real device charges or drains.

Nothing is sent anywhere — every value is read and displayed locally, entirely within your browser.

Not every browser exposes every metric; unsupported ones are clearly labeled as such, never faked.

A worked example

Plug in your charger and the real charging indicator flips live, exactly in step with your device's actual charging state.
