Battery Logger: Monitor Your Battery Health

Battery Logger is a comprehensive application designed to observe and record your device's battery health. With this app, you can easily check your daily battery status, ensuring that you stay informed about any potential issues.

The app runs a background service that continuously logs changes in your battery's charge level, temperature, voltage, and charging state. This data is stored for later review, allowing you to track patterns and identify any anomalies in your battery's performance.

You can view the recorded information in two formats: a list or a graph. The list screen displays detailed data points including the timestamp, remaining battery percentage, temperature, voltage, and charging status. For charging events, it captures the start and end times of charging sessions as well as the data at full charge. For discharging events, it records every instance where the battery level decreases. On the graph screen, you can visualize how the battery's remaining charge, temperature, charging connection status, and screen on/off state change over time using line graphs.

While the app is running, it also displays the current battery percentage in the status bar, providing quick access to important information at a glance. However, please note that certain devices may have battery optimization settings that could interfere with the app's functionality. If you encounter issues, you might need to adjust these settings to ensure the app continues to run smoothly without being stopped by the system.

By using Battery Logger, you can gain valuable insights into your battery's behavior and take proactive steps to maintain its health.
