Adaptive Battery is a feature designed to extend the battery life of devices by learning how users interact with their apps. It prioritizes power for frequently used applications while limiting resources for those that are rarely accessed. This helps to conserve energy and improve overall device performance. The technology works by analyzing usage patterns over time, allowing the system to make intelligent decisions about which apps to keep active and which to restrict. As a result, users can enjoy longer battery life without needing to manually manage their app settings.
