adb shell dumpsys batterystats

The adb shell dumpsys batterystats command is used to gather information about battery usage statistics on an Android device. This command provides detailed statistics related to how the device’s battery is being used by various apps and system components.

Here’s an example of how you can use it:

$ adb shell dumpsys batterystats

The output will include information about various aspects of battery usage, including usage details for individual apps, wake locks, and other components.

If you want to focus on specific information or reset the battery statistics, you can use additional options. For example, to reset the battery statistics, you can use:

$ adb shell dumpsys batterystats --reset

To get battery usage statistics for a specific package (app), you can include the package name as an argument:

$ adb shell dumpsys batterystats com.example.myapp

Replace com.example.myapp with the package name of the specific app you are interested in.

As with other dumpsys commands, you can redirect the output to a file for easier analysis:

$ adb shell dumpsys batterystats > batterystats_dump.txt

This will save the output to a file named batterystats_dump.txt in the current directory.

Battery statistics can be useful for developers and system administrators to understand how the device’s battery is being used over time and to identify any applications or services that may be consuming a significant amount of power.
