Screen Wake Lock API
Checking compatibility...
Prevent devices from dimming or locking the screen when an application needs to keep running. Perfect for reading, presentations, or applications that don't require user interaction.
The Screen Wake Lock API may not be supported in all browsers and may require a secure context (HTTPS). Some devices may override wake lock requests based on system settings or battery state.
