Keep Your Screen Awake Without Installing Anything

This page asks your browser for a screen wake lock. Nothing is installed and no system setting is changed for good: you press one button, the display stops dimming, and you press it again or close the tab to hand control back to the operating system.

A worked example. Say you are following a recipe on an Android tablet and the screen goes dark every 30 seconds. Open this page in Chrome, tap the wake lock button, and the status shows the lock is active. Your hands stay covered in flour and the display stays lit. Switch to another app and the browser drops the lock to save battery. Come back to the tab and the tool tries to take it again on its own.

Which browsers support it. Chrome, Edge, and other Chromium browsers on desktop and Android support the Screen Wake Lock API. Safari does not, so on an iPhone or iPad you need the manual route: open Settings, go to Display and Brightness, then Auto-Lock, and choose Never. Guided Access is the better pick when only one app needs to stay awake on a supervised device. Both fallbacks are written up in stopping Meet and Teams from sleeping your screen.

If the button seems to do nothing.

1. Bring the tab to the front. A hidden tab cannot hold a lock.
2. Check the battery. A low charge can make the browser refuse.
3. On iOS, stop looking at the page. The platform has no wake lock, so use Auto-Lock or Guided Access.

Before you leave it on. The lock holds only while the tab is visible, so minimizing the window or switching tabs can end it. A lit screen also drains the battery faster, which matters on a laptop that is not plugged in. The countdown timer sits well beside it, and this overview for remote work covers longer sessions.

Keeping a Tablet Screen On for a Long Recipe or Workout

Open the page, press the start button, and the display stops dimming until you press stop or close the tab. The status area reports whether the lock is active, and the session timer starts from the moment the lock is granted rather than from the moment you clicked. A two-hour cooking session therefore reads 120:00, and the timer continues past an hour rather than rolling over, so a long session never displays as a small number.

The lock lives and dies with the tab. Switching to another app or another tab hides this page, and the browser releases the lock at that point to save battery. Come back and the tool asks for the lock again on its own, so the display stays awake for the rest of the session without a second click. Closing the tab releases the lock as well, which matters when the device is shared and you do not want to leave the screen on for whoever picks it up next.

When the Start Button Is Disabled or Does Nothing

If the browser has no wake lock API, the button is disabled from the first load and the page shows fallback instructions instead of letting you press something that cannot work. Support covers Chrome, Edge, and other Chromium browsers on desktop and Android; Safari has no wake lock support on iOS, so the manual route there is Settings, then Display and Brightness, then Auto-Lock, then Never. On a supervised device, Guided Access keeps one app awake without unlocking the whole device.

Two other conditions can stop a request that would otherwise succeed. The page has to be served over HTTPS, and the tab has to be visible at the moment of the request. Chrome may also decline the request on a device with a low battery, in which case the page reports the failure and the start button becomes available again. If the status does not switch to active, bring the tab to the front, check the charge, and try once more.

Battery and the Rest of the Session

A lit display is the largest single power draw on a laptop, so leaving the lock on after the demo or the video finishes costs measurable battery. The session timer is the reminder to turn it off, since it keeps counting for as long as the lock is held. Plugging in is the simple answer for a long session, and the manual routes for meeting software are in stopping Meet and Teams from sleeping your screen. For work sessions with a stop point, the countdown timer pairs well with it, and this overview for remote work covers longer stretches at the desk.
