    How to Generate Battery Usage Report in Windows 10


    information   Information
    A battery usage report will help you know more about the usage, health, and life estimates characteristics of your PC's battery over the lifetime of the system.

    This tutorial will show you how to generate a detailed battery usage report for your Windows 10 PC (ex: laptop, Surface, or tablet) that runs on a battery.




    Here's How:

    1. Open a command prompt.

    2. Type the command below to have the battery report as a .html (recommended) or .xml file, and press Enter. (see screenshot below)

    (For .html file.)
    powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.html /Duration days

    OR

    (For .xml file)
    powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.xml /XML /Duration days

    Note   Note
    Substitute days in the commands above with a number 1 to 14 to specify the number of days you want to analyze for the report.

    3. Double click/tap on the say battery_report.html file on your desktop to open and see your battery usage report in your default web browser (ex: Internet Explorer).

    4. This is a copy of my laptop's battery usage report from a battery_report.html file viewed in Internet Explorer as an example of what is reported. (see screenshots below)


    The top of the battery usage report will give you general information about your PC as well as if your PC supports connected standby or not.

    The Installed batteries section below gives you detailed information about the battery including the name, serial number, and manufacturer.
    • Chemistry = Usually will be LION for Lithium-ion battery.
    • Design Capacity = The amount of charge that the battery was designed to hold in mWh (milliwatt hours).
    • Full Charge Capacity = The amount of charge that the battery will actually hold.
    • Cycle Count = The number of times that the battery has used up 100% of its charge and then recharged, or the result of discharging to 50%, charging to full, then discharging to 50% again. Batteries have a limited amount of cycles to work through before they are considered consumed.

    The Recent usage section below lists the power states (active or suspended) that your system has gone through over the last specified days (ex: 3 days). You will also see if the power "source" was AC or battery, and the remaining capacity shown as a percentage and mWh.

    The Battery life estimates section below will help indicate how long you can expect the battery to last at a "full charge capacity" and at "design capacity" based on the observed drains.

    A cool "hidden" tool. I just tried it on my laptop using powercfg /batteryreport. My laptop is plugged in 24/7(used to be a desktop replacement, now just a backup/test machine) for the last 5 years. I just generated a report out of curiosity:

    People who do use the battery though, should do a report more often than once in 5 years

    Is there a way to reset this report?

    The reason why I ask, is lately my report is off, like way off. When it used to give me realistic battery life results it was around 10 to 11 hours. Now it's showing 149000 hours!?!?

    Any suggestions or recommendations would be appreciated.

    Cheers!

    Hello radar,

    That's some great battery life you have there.

    The report is a newly generated report each time it's ran, so there's no need to try and reset it.

    If able, you could see if removing the battery, and pressing the power button while also unplugged from AC to discharge may help the next time you run the report.

    You might also double check to make sure that you have all of the latest drivers installed for your PC and devices to see if that may help.

Windows 10 resource usage in Installation and Upgrade
One of the good things is the small footprint of Windows 10. In my installation it uses only 8.5GB on the C partition and less than 500MB of RAM. I am sure that willl grow somewhat with the RTM edition, but it is a good start. 72517252
