Battery Monitor1.7.3

Battery Monitor shows your device’s battery level, health, temperature, voltage, and other status details in real time, helping you spot changes before they become a problem. It suits people who want closer visibility into battery condition, charging behavior, and unexpected drain during everyday phone use. A persistent notification can display the current level and status, with optional additional battery details selected by the user.

On Android 16 and newer, that notification can appear as a Live Update showing the battery level or temperature. Configurable alarms can signal a full charge, low battery, chosen charge thresholds, temperature conditions, or changes in battery health. Home screen widgets keep selected battery information visible without opening the app.

The app records battery events over time, allowing its history to be filtered and exported as a CSV file for analysis in another program. On devices and configurations that support them, root access or Shizuku can reveal advanced battery information, while Battery Monitor does not collect, store, or transmit personal data.

Battery Monitor is an open-source Android System Tools app with a Universal architecture; version 1.7.3 requires Android 8.0 or later. This release improves the reliability of voltage readings and corrects notifications that previously opened Alarms instead of Current State.
