Battery report in Windows 10 and Windows 8

Windows 10 and Windows 8 have a nice feature to build a battery report. Using the data provided in that report, you can get a lot of useful information about your battery, including how its capacity has decreased over time and battery usage statistics.


This is possible thanks to the built-in tool powercfg. Since Windows 8, it is able to generate a detailed report in HTML format about your battery. You can create it as follows.
  1. Open an elevated command prompt.
  2. Type the following command:
    powercfg /batteryreport

    The output will be as follows:batteryreport

  3. Now, open the file created by powercfg in your favorite web browser.

The report generated by powercfg includes a lot of information which is grouped into logical sections. It starts with general information about your device, including its manufacturer and the model name.general info

The Installed batteries section comes with detailed info about its name, serial number, and battery chemistry type. It also includes the design capacity, charge cycle count and full charge capacity. The last parameter, when compared with the design capacity value, shows how much the battery has degraded over time. The charge cycle count shows how many times the battery was charged.installed batteries

In the Recent usage section, you will find power statistics for the last 3 days. It shows when the device was in use, suspended, charged and how much battery capacity remained for each event.recent usage

The section Battery usage contains a graph which shows how your battery discharged over the last 3 days. Under the graph, you will find a table which contains the same data in detail.battery usage
