Here is an example of the health status of my one-year-old Surface Pro 4 battery. Let’s now take a look at two real-life examples of bad and good batteries. To do so, we will need to take a number of the last full charge value, divide it by the number representing the design capacity, and then multiply the result by 100 to convert it to the percentage value. Using these two numbers we will be able to determine the battery health status. One particular part of this report we are mostly interested in would be “Battery Information” – specifically design capacity and last full charge values. You can then review and correct detected system errors or warnings. Here you will find your system analysis and power efficiency diagnostics report. If they don’t open up in a web browser by default, right-click on the file name and select “Open with” option and choose your preferred web browser from the list. Both reports should appear at the top of the list. This folder has a lot of content, and to quickly find the energy reports you can start typing “energy…” or simply sort the content of the folder by date, newest to oldest. Next, navigate to the System32 folder and review the reports we just generated. You can find this report in the same location on your C: drive. We are done with the command prompt, so you can close it now. This command will generate another report in HTML format called “battery-report.html”. You can open it using any web browser.īefore we look at the energy report, let’s run another command called “powercfg /batteryreport”. The complete energy report will be saved to C:\WINDOWS\system32\energy-report.html location in HTML format.
