Frequently Asked Questions
Everything you need to know about NoSleepScreen and browser-based wake lock.
Does NoSleepScreen work on all devices?
NoSleepScreen uses the Screen Wake Lock API where available. It works best in modern Chromium browsers and on secure pages such as localhost or HTTPS.
Is NoSleepScreen safe to use?
Yes. The tool runs in your browser and does not install software. It only requests a wake lock while the page is open and visible.
Does it consume more battery?
Keeping a screen awake can use more battery, especially on mobile devices. Use shorter timers whenever you only need a temporary session.
What happens when the timer ends?
The app releases the wake lock, resets the controls, and lets your device return to its normal sleep behavior.
Do I need to keep this page open?
Yes. Browsers usually release wake lock when the tab is hidden, minimized, or closed. That is why NoSleepScreen uses a visible timer-based workflow.
