Device Health Services is a system application that comes installed by default on most of the modern Android devices. This application collects data and uses it to customize the user's experience and optimize resource usage by managing the device's sensors. With Device Health Services, users can for example gain insights into battery usage, predict how long the battery will last based on current usage patterns, and receive tips to extend battery life.
