Seven good reasons to keep your screen awake

Screens go to sleep because the system assumes nobody is using them. Sometimes that assumption is wrong. Someone is following a process, but not touching the keyboard or screen. These are the situations where preventing sleep makes a real difference, and what to watch for in each.

1. Following a recipe

Hands covered in dough do not want to unlock a phone every 30 seconds. Propping a phone or tablet on the counter with the screen kept awake makes a recipe usable. Set a timer for the length of the cook, and lower brightness so the display is not blinding in a dark kitchen.

2. Presenting or teaching

A presenter who pauses to talk through a slide can find the display dimming at the worst moment. Keeping the screen awake for the length of a meeting avoids that. Pair it with a timer that matches the schedule, so the laptop returns to normal sleep behaviour afterwards.

3. Watching a dashboard

Operations teams, traders, and developers often keep a status page, build monitor, or analytics board open on a spare display. These screens need to stay readable at a glance. A browser tab with a wake lock on a second monitor is a simple way to do this without changing system-wide power settings.

4. Reading long documents

Reading a long article, paper, or e-book on a laptop or tablet means minutes pass between interactions. Most systems dim the screen after two to five minutes of no input, which is irritating when your eyes are working but your hands are not.

5. Kiosks and shared displays

A menu board, event schedule, or sign-in screen needs to stay on all day. For permanent installations, the right answer is a system-level setting or dedicated kiosk software. For a one-off event, a browser tab with a wake lock is quicker to set up and easy to undo.

6. Reference material while working

Many people keep a tutorial, spec sheet, or checklist visible on a second device while they work on the first. If the reference screen sleeps every few minutes, you lose time waking it. Keeping it awake in a small window is a sensible fix.

7. Testing displays

When checking a new monitor for dead or stuck pixels, you need to cycle through solid colours and look carefully, which takes longer than the usual timeout. The colour test in Screen Awake fills the page with a single colour and keeps the display awake while you inspect it.

When not to keep the screen awake

• When the device is on battery and you are not looking at it.
• On OLED displays showing a static image for many hours, because of burn-in risk.
• On shared or public computers, where leaving a screen unlocked is a security risk.
• When you are away from the device. Always turn the feature off before you leave.

A simple rule

Keep the screen awake for as long as a person is actively using what is on it, and not a minute longer. A timer is the easiest way to enforce that rule.
