Frequently Asked Questions

How does Screen Awake keep my screen on?

It uses the Web Wake Lock API, a browser standard that prevents your device from sleeping. On older browsers, it falls back to playing an invisible silent video, which also prevents sleep.

Does it drain my battery faster?

Keeping the screen on will use more battery than letting it sleep, similar to watching a video. Use the brightness slider to reduce power consumption. The Wake Lock API itself uses minimal resources.

Does it work on iPhone and iPad?

Yes! Safari on iOS supports the Wake Lock API. The video fallback also works on older iOS versions. Make sure the browser tab stays in the foreground.

Is it really free?

Yes, completely free, with no registration. Everything runs in your browser.

Can I set it to run for days or weeks?

Absolutely! You can set any custom duration — minutes, hours, or days. Or choose "Forever" to keep the screen on indefinitely until you manually turn it off.

Will it work if I switch to another app?

The Wake Lock API requires the browser tab to be visible. If you switch to another app, the screen lock may re-engage. Keep the browser tab open and visible for best results.

What are the sound pulse options for?

Optional quiet audio pulses help keep the audio session alive on mobile devices. They can also serve as a gentle ambient sound. You can keep them off if you prefer silence.

Why do I need this tool?

It is useful for reading long articles, following recipes while cooking, giving presentations, monitoring dashboards, keeping maps visible while driving, or any situation where you need your screen to stay on.
