Navigator: wakeLock property
Baseline 2025
Newly available
Since March 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The wakeLock read-only property of the Navigator interface returns a WakeLock interface that allows a document to acquire a screen wake lock.
While a screen wake lock is active, the user agent will try to prevent the device from dimming the screen, turning it off completely, or showing a screensaver.
