Querying Android Device Battery Status via ADB Shell Commands

30 November 2024 Stephan Petzl Leave a comment Tech-Help

Understanding the current status of an Android device can be crucial for developers and testers. One of the most common inquiries is about the device’s battery status. This article will guide you through the process of querying battery information using ADB (Android Debug Bridge) shell commands.

Using ADB to Retrieve Battery Information

ADB provides a powerful way to communicate with an Android device. You can easily retrieve detailed information about the device’s battery status without needing root access. Here’s how:

Basic Command for Battery Information

To get a comprehensive overview of the battery status, you can use the following command:

adb shell dumpsys battery

This command outputs various details such as the battery level, health, voltage, and more.

Advanced Options for Battery Information

If you require more specific information or want to customize the output, consider using the cmd utility:

Command for Detailed Battery Attributes


adb shell cmd battery get level
adb shell cmd battery get status
      

These commands allow you to query specific attributes like the battery level or current status.

Customizing Output

For a tailored output, you can use shell scripting to format the data:


batstats="ac usb wireless status level temp present counter invalid"
for batstat in $batstats; do
  value=$(adb shell cmd battery get "$batstat")
  printf "%-8s: %s\n" "$batstat" "$value"
done
      

This script will display a formatted list of battery statistics.

Practical Application in Testing

Having the ability to query battery information is particularly useful in automated testing scenarios. For example, you might want to ensure that your app behaves correctly under different battery conditions.

Our product, Repeato, a no-code test automation tool, can seamlessly integrate these ADB commands into your testing workflow. Repeato allows you to run and maintain automated tests for your apps efficiently. With built-in support for ADB commands, you can easily execute commands like dumpsys battery within your test scripts to verify app behavior under various battery states.
