Android Battery Saver System

An Android battery saver that monitors app and device behaviour and reduces unnecessary power drain.

An Android battery saver that monitors app and device behaviour and reduces unnecessary power drain. As a reference project it shows how a system like this is put together in practice, which parts matter and how they are tested, so that a developer can learn from it and build on it.

It suits learners building mobile skills: screens and navigation, local and cloud data, notifications, and publishing a working app.

The main parts are secure sign-in, clean screens for the main user journeys, cloud data with offline-friendly handling, and notifications for important events. The reference build uses Kotlin, Android SDK, Firebase, and REST API, with a clear project structure, setup instructions and sample data so that it can be run and extended.
