About the Screen Wake Lock Test
The Screen Wake Lock Test holds your screen awake using the Wake Lock API, for checking kiosk displays, recipe pages and dashboards. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Testing a kiosk or dashboard that must not dim.
- Checking wake lock support before relying on it.
Frequently asked questions
The lock keeps releasing itself.
That is by design. Switching tabs, minimising the window or locking the device all release the lock automatically, and the browser refuses new locks when the battery is very low.
Is there a limit on how often I can use the Screen Wake Lock Test?
It is free, with no account, no trial and no daily cap. Every device tests tool on inputtesthub.com works the same way: open the page and use it.
Does anything I enter leave my computer?
No. The Screen Wake Lock Test runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
Who is the Screen Wake Lock Test for?
The most common reasons people reach for it: testing a kiosk or dashboard that must not dim. Checking wake lock support before relying on it. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Does the Screen Wake Lock Test need an app or a driver?
No installation, no extension and no driver. The Screen Wake Lock Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
