The following two use cases are now possible.

  • Seamless presentations: The API prevents screens dimming in web-based presentation or slideshow apps, so presenters can now deliver a polished and professional experience.
  • Recipe sites: The API can keep the screen on, so users don't need to worry about the screen turning off while their hands are full of dough when following a baking recipe.

For full details about using the API, check out Stay awake with the Screen Wake Lock API. The following code snippet shows the most common interactions.

// The wake lock sentinel.
let wakeLock = null;

// Function that attempts to request a screen wake lock.
const requestWakeLock = async () => {
  try {
    wakeLock = await navigator.wakeLock.request();
    wakeLock.addEventListener('release', () => {
      console.log('Screen Wake Lock released:', wakeLock.released);
    console.log('Screen Wake Lock released:', wakeLock.released);
  } catch (err) {
    console.error(`${}, ${err.message}`);

// Request a screen wake lock…
await requestWakeLock();
// …and release it again after 5s.
window.setTimeout(() => {
  wakeLock = null;
}, 5000);
