Power Saving Mode is a feature found in many electronic devices, such as smartphones, laptops, and tablets. It helps extend battery life by reducing the device's performance and limiting background activities. When activated, this mode may dim the screen, turn off non-essential apps, and decrease processing power to conserve energy. This mode is particularly useful when the battery is low and charging is not immediately available. Users can enable Power Saving Mode through the device's settings, allowing them to continue using their device for essential tasks without worrying about running out of battery too quickly.
