Use-Case Guide
Presentations are one of the clearest reasons to use a wake-lock tool, but a smooth demo still depends on preparation. This guide focuses on the practical details that help you avoid awkward screen sleep during live sessions.
Presentation sessions usually happen in a single visible tab or window, and the presenter often knows the rough length of the meeting. That makes them a strong match for a timer-based wake-lock tool. Instead of changing a device's global sleep settings, the presenter can start a session only when it is needed.
Screen sharing itself does not guarantee wake lock. If the browser tab that requested wake lock is hidden or backgrounded in a way the browser dislikes, the session can still be released. The best habit is to keep the wake-lock page accessible and avoid bouncing between many windows during a critical demo.
If you are running an unusually long booth display, conference kiosk, or unattended meeting room setup, changing the device's managed display settings may be more reliable than depending on a browser tab. NoSleepScreen is most useful for short to medium-length sessions where a user remains nearby.
Use NoSleepScreen as one layer of preparation, not the only one. Start the timer before your session, keep the page visible, and do a short live test. That small rehearsal catches most problems before your audience sees them.
