Windows ships with built-in operations to generate a battery report, a detailed status report highlighting useful information about the battery and its usage history.

If you run the Windows operating system on a battery powered device, you are probably keeping an eye on the battery status regularly to make sure the system won't just shut down at one point in time due to a lack of power.

Windows informs you if power runs low, about the current battery status, and as we have shown recently, provides you with options to analyze and reduce power usage.

Battery Report in Windows

The Windows operating system ships with built-in options to generate battery reports. Unfortunately, these reports are generated from the command line which is probably the core reason why they are only used by admins and power users, and not regular users.

Note: Battery Report has been added to Windows 8 and is not available in older versions of the operating system.

Please note that you need to go through a couple of power cycles before you start generating the report as it won't reveal much if you don't. If you start it right after setup for instance, it won't show any history as the data is not there yet.

Two things come together here: first, the generation of the power report using the command line, and second, analyzing the data that it provides.

Generating the report

generate battery report command prompt

The following steps are required to generate the report. Please note that you can generate the report on Windows 10 and previous versions of Windows, it is not a Windows 10-only feature.

  1. Tap on the Windows-key, type cmd.exe.
  2. Right-click on the Command Prompt result that appears, and select "run as administrator" from the context menu that opens.
  3. Confirm the UAC prompt that appears afterwards.

Now that the command prompt window with elevated rights is open, run the following command:

powercfg /batteryreport /output "c:\battery_report.html"

Alternative: run powercfg /batteryreport instead. This saves the report to the user folder under the name battery-report.html.

You can change the output path to another location on your system but need to make sure that the directory you want it created in exists before you run the command.

You may also want to run the following command to create an Energy Report as well.

powercfg /energy /output "c:\energy_report.html"

Powercfg Notes

Powercfg is a mighty tool that supports lots of command line options that you can play around with. Some commands that you may find useful are:

  1. powercfg /a lists all sleep and standby states that the device supports.
  2. powercfg /list lists all power schemes in the current environment.
  3. powercfg /hibernate on|off turns hibernation on or off.
  4. powercfg /lastwake reveals which event woke up the computer most recently.
  5. powercfg /energy creates a Power Efficiency Diagnostics Report.
  6. powercfg /batteryreport creates the Battery Report.
  7. powercfg /sleepstudy shows which device drivers and applications are waking up the computer in Connected Standby mode.

The Battery Report

Now that the report has been generated by Windows, it is time to open it. Since it is saved as a HTML file, it can be opened in any web browser available on the system.

Open Windows Explorer and navigate to the folder that the generated report was saved in. Double-click on it to open it in the default web browser, or pick one of the available programs from a list.

The report itself can be divided into several parts.

The Overview

battery report windows

Displays information about the computer system, BIOS, build, as well as installed batteries, capacity and even the serial number of the battery.

Recent Usage

recent usage

Highlights the power states of the last three days. This includes the state (connected standby, active, suspended), the source (battery or AC), and the capacity remaining in percent and mWh.

Battery Usage

battery usage

Battery Usage highlights the battery drain of the last three days. It is very similar to recent usage, but shows you the energy drain at a specific time of day instead.

Usage history

usage history

The Usage History displays when the system has been used, and divides the time between battery and AC.

Stats for the last seven days are shown individually, while previous periods are shown as weekly reports instead.

Battery Capacity History

battery capacitor history

The battery capacity history highlights the charge capacity of the battery over time. If the full charge capacity and the design capacity diverge too much, it may be time for a new battery.

Battery life estimates

battery life estimates

Last but not least, the battery usage reports displays battery life estimates based on the monitored power drain. This is again useful in determining the effectiveness of the battery but can be affected by how the computer is used and how it is configured when it is powered by battery.

If you play games, or use the device for other power-intensive activities, then you will notice a lower battery estimate than running less intensive tasks on the system.

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

    5. Rufus
    6. Ventoy

    PS. I hate reading these “SEO optimized” articles.

    1. cdr said on January 15, 2023 at 3:32 pm

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    ps…. time travelling?

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

  5. basingstoke said on January 16, 2023 at 11:18 am

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

    1. Heinz Strunk said on September 19, 2023 at 3:57 pm

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    Microsoft has removed KB5029351 update

    1. EP said on August 24, 2023 at 9:21 pm

      only from windows update though
      KB5029351 is still available from the ms update catalog site

  7. Anonymous said on August 24, 2023 at 11:05 pm

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

  8. john said on August 24, 2023 at 11:17 pm

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

    1. John G. said on August 25, 2023 at 12:08 pm

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
