Windows 10 allows the user to create a special report which shows battery usage in detail. It can be done without third-party tools. The only application you need is the built-in console tool "powercfg".
To create the mentioned report, the powercfg app is using the System Resource Usage Monitor (SRUM). The data obtained from SRUM can be saved in a CSV file. Alternatively, you can save it as an XML file.
Powercfg supports a special command line argument, /srumutil, which generates the battery energy estimation report in Windows 10. Run the command powercfg /srumutil /? to learn more details of this feature.
Let's see how to create a new report.
- Open an elevated command prompt.
- Type or paste the following command to create a new report as a .csv file:
powercfg /srumutil /output %USERPROFILE%\Desktop\srumutil.csv
To create an .xml file, type or paste the following command:
powercfg /srumutil /output %USERPROFILE%\Desktop\srumutil.xml /XML
Now, you can open your CSV and XML files in an appropriate app to read the report.
Alternatively, you can get detailed information about battery usage using Settings and its Battery Saver page. It contains less technical details, however, it is more user friendly.
- Open the Settings app.
- Go to System - Battery:
- On the right, click the link "Battery usage by app". The following page will be displayed:
