I'll create a comprehensive demo to showcase the Screen Wake Lock API, with special attention to mobile browser compatibility and user experience.

I've created a comprehensive Screen Wake Lock API demo that showcases all the key features and considerations for mobile browsers. The demo includes:

Key Features:

• Real-time status tracking - Shows whether wake lock is active or inactive
• Browser compatibility detection - Automatically detects and displays browser type and API support
• Activity logging - Real-time log of all wake lock events and interactions
• Mobile-optimized UI - Responsive design that works great on phones and tablets
• Error handling - Graceful handling of unsupported browsers or API failures

Mobile-Specific Considerations:

• iOS Safari compatibility - Detects iOS devices and shows appropriate messaging
• Page visibility handling - Automatically detects when the page becomes hidden (common on mobile)
• Touch-friendly controls - Large buttons optimized for mobile interaction
• Clear status indicators - Visual badges showing current state

Testing Instructions: The demo provides specific testing steps for both mobile and desktop, helping users understand how the API behaves in different scenarios like tab switching, app switching, and screen timeout periods.

This demo will help you understand exactly how the Screen Wake Lock API works across different mobile browsers and provides a solid foundation for implementing it in your own applications!

Let me first read the current implementation to understand how to add auto-start functionality.

Perfect! I've updated the wake lock demo to automatically start when the page loads. The key changes include automatically requesting the wake lock when the API is detected as supported, auto-restarting the wake lock when users return to the tab after it was hidden, and updating the UI descriptions to reflect the new auto-start behavior. Now users will immediately see the wake lock in action without needing to manually click the button first!
