On iOS devices, the feature that prevents the display from dimming or turning off automatically is a user-configurable setting. This function keeps the screen illuminated continuously until manually deactivated or the device battery is depleted. A common instance of its application involves following recipes while cooking, where the user needs uninterrupted visibility of instructions without touching the screen.
Maintaining the screen’s illumination offers several advantages, particularly for tasks demanding constant monitoring of information. This includes navigation, presentation of dashboards, or accessibility needs where repeated screen activation is undesirable. Historically, operating systems have included power-saving mechanisms, and this particular setting provides a temporary override of those systems for specific use cases. Disabling automatic screen lock enhances immediate usability at the cost of increased energy consumption.
