Generate a Battery Report in Windows

If you are a laptop or Surface user then you might be interested in looking through a report on your battery and you can do this by running a very simple command within Windows. All you need to do is to open a Command Prompt by right clicking on your Windows 10 Start button and selecting “Command Prompt”: When the Command Prompt appears then type in the following command:

powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.html

This will now generate a battery report to your computer’s Desktop for you to view and analyse! You can change the output path if you want to save it somewhere else, for example to your Documents folder or a network share.

How to Read Your Battery Report

Once the HTML file opens, there are a few sections worth paying attention to:

• Design capacity vs. full charge capacity – this shows how much your battery has degraded compared to when it was new. A big gap between the two usually means the battery is on its way out.
• Battery life estimates – near the bottom of the report, this table compares your battery’s runtime when new against its current runtime, based on recent usage.
• Usage history – shows charge/discharge cycles over the last few days, useful for spotting apps or background processes that are draining the battery faster than expected.
