Battery Health Checker App for Android

About this project

Battery Health Checker is a modern Android app built with Kotlin and Jetpack Compose that shows your battery’s real-time temperature, charge level, voltage, charging status, and health. It listens to Android’s system battery broadcasts, so the values update live. The interface uses glassmorphism cards, an animated circular temperature gauge, and a dark mode-friendly Material 3 design.

Objectives
