The duration a device’s display remains active before automatically dimming and turning off is a user-configurable setting. Adjusting this setting allows users to control power consumption and maintain visibility of information for preferred periods. For example, someone frequently referencing instructions may prefer a longer duration than someone primarily using the device for quick notifications.
Extending the display’s active time can enhance productivity by minimizing interruptions caused by frequent screen lockouts. This can be particularly beneficial during tasks requiring constant monitoring or input. However, increasing the duration can also impact battery life, as the display consumes significant power. Historically, default timeout values were shorter to preserve battery, but modern devices offer greater user control to balance usability and power efficiency.
