What Compatibility Means

NoSleepScreen depends on the browser's screen wake lock feature. A supported browser can request that the display stay awake while the tab is open and visible. An unsupported browser still loads the page, but it may not be able to prevent screen sleep through the web API.

Why Wake Lock Can Stop

Browsers may release a wake lock when the tab is hidden, the device enters battery saver mode, the screen is manually locked, or an organization policy blocks the request. NoSleepScreen watches for these changes and shows status updates so users know what happened.

Best Browser Choice

For the most reliable keep-screen-awake experience, use a current version of Chrome or Edge on desktop, or a modern Chromium browser on Android. If Safari does not keep the screen awake for your device, try Chrome or Edge and keep the NoSleepScreen tab visible.
