Pro Tips & Recommendations
Get the most out of your screen awake sessions.
Keep the Tab Visible
Most modern mobile and desktop operating systems pause wake lock if a browser window is completely minimized or backgrounded.
Dim Screen for Extended Battery
If using on battery power for long reading sessions, reduce your device brightness to conserve power while keeping the display on.
Use Timer for Overnight Tasks
Set a 1h or 2h duration when running lengthy file downloads or render tasks so your screen automatically sleeps after completion.
Keep Your Screen On on Any Device
One click works the same across every phone, tablet, and laptop.
A wake lock behaves slightly differently on each platform, but the result is always the same: your display stays awake for as long as you need it. Here is what to expect on the devices you use most.
iPhone and iPad
Open the page in Safari on iOS 16.4 or later, tap the button once, and leave the tab in the foreground. For the most reliable result, turn off Low Power Mode, which can override the wake lock and let the display dim earlier than expected.
Android phones and tablets
Works in Chrome and Samsung Internet on devices from Samsung, Xiaomi, OPPO, Huawei, and others. There is no app, APK, or Play Store download - just open the page and tap the button, then keep the browser tab visible for continuous wake.
Windows laptops and desktops
Use Chrome or Edge on Windows 10 and Windows 11. The tool asks the operating system not to dim the display, so you never have to change your Power & Sleep settings or request admin rights from IT.
Mac laptops and desktops
Works in Chrome, Safari, and Edge on macOS. If the screen still dims, open System Settings → Displays → Advanced and make sure "Prevent automatic sleeping on power adapter" is not blocking the browser wake lock.
Samsung Galaxy
Open it in Samsung Internet or Chrome on any Galaxy phone or tablet. It is a fast, task-specific alternative to Smart Stay and the system screen-timeout setting, and it also works in Samsung DeX mode.
No matter which device you use, the flow is identical: open this page, tap the power button, and let the display stay awake for exactly as long as you need. When you are done, one more tap releases the lock and your device returns to its normal timeout behavior.
