Power settings are configurations on electronic devices that manage how they use energy. These settings can help extend battery life, reduce energy consumption, or optimize performance. Common options include sleep mode, screen brightness, and power-saving features, which adjust the device's functionality based on user preferences or activity. Users can typically access power settings through the device's control panel or settings menu. Adjusting these settings allows individuals to customize their experience, whether they are using a laptop, smartphone, or desktop computer. Proper management of power settings can lead to improved efficiency and longer device lifespan.
