A screen that dims mid-recipe or disappears during a presentation can break your rhythm. A short wake-lock session is useful when you need a reference to remain in view.
Try matching your awake timer to a focused work session. A 30-minute timer gives you a clear stopping point without leaving your display running all day.
Keeping a display on uses more energy. Choose only the time you need, reduce brightness when comfortable, and stop the session when you finish.
