How to create a battery report in Windows 11

We always want to make sure we have enough energy to get through the day or through a certain part of the time when we can’t get to our chargers. Image

Monitoring battery levels on our devices is something that many of us do instinctively

But if you’ve tried to look at the battery indicator on your laptop, you may have noticed that the estimated remaining time rarely matches what you’re actually getting. Fortunately, if you want a clearer picture, you can create a battery report in Windows 11 (and earlier versions) to find out everything you need to know about it. As for the battery indicator on the taskbar, it usually only gives you an estimated battery life based on what you’re doing at the time, plus it may not take into account how much battery is used if you’ve had a laptop for a long time. However, if you want a more detailed picture of what to expect from your laptop’s battery, Windows 11 continues to make it easier to create and read a battery report. The Battery Report will contain all the information you might want about your laptop battery, including who made it, capacity, previous usage data, and battery estimates.

Create a battery report on Windows 11

While it may sound a bit technical, creating a battery report is actually very simple and risk-free. Here’s how it goes:

  • Right-click the Start icon on the taskbar (or press Windows + X), and then select Admin from the list of options. If you uninstalled the Windows terminal from your computer, this option will read Windows PowerShell (Admin).
  • Accept the User Account Control (UAC) request, which will require administrator privileges.
  • Copy the following text, then paste it into the Windows Terminal / PowerShell window: powercfg /batteryreport /output “C:\battery_report.html”
  • This will report the battery report as an HTML file at the root of your C: drive. You can export the file to any folder by changing the path specified at the end of the command.
  • Press Enter and a report will be generated.

That’s all you need to know about creating a battery report, but there’s a question of reading and understanding what it says.

What’s in the battery report

There is a lot of information in the battery report for Windows 11, so we will try to help you understand everything that appears here. The top of the report includes some general information about your laptop, including the version of Windows you’re using, as well as your firmware. This should not be the most interesting part of the report, but what follows is a little more interesting. The first section is called Installed batteries and summarizes the battery information in your laptop. This includes the manufacturer, the chemical – which will almost certainly be lithium-ion (LIon) – the projected capacity and the full filling capacity. There may be a small deviation between these two capacity values, and what will be most important is the full charging capacity, because that is how much power the battery can actually withstand.

Next, you will see recent information on battery usage. The first table includes a list of recent changes in power status in the last three days, as well as battery status at that time. Every time you turn off the laptop, put it in sleep mode and so on, it is recorded here. Below is a graph that specifically shows the laptop’s power consumption in the last three days. Of course, this will include any information only if you have used a battery-powered laptop. This allows you to see how quickly the battery discharged while you were unplugged, so you can get an idea of ​​how long the battery lasts. The following two tables have even more historical data.

The information in this chart will include information on battery usage since the last time you performed a clean installation of Windows or since you purchased it. The first table includes a summary of the time your laptop was used each week. This combines active use and standby time for connection, both while on battery and while plugged in. The following table includes information about your laptop’s battery capacity over time, so you can see how much it may have used up. Finally, there is the section that might interest you the most, estimates of battery life.

The data in this table is also based on all of your historical battery usage data, so you can see estimates of how long the battery can last based on your usage and battery capacity, both for active use and associated standby. For older dates, this information is aggregated by week, but the last seven days are displayed individually. At the very end, you can also see a general estimate based on all battery discharge cycles since you installed the operating system. With all of this, you should be able to estimate exactly how long your laptop’s battery should last when fully charged. This is the best way to learn everything you need to know about your laptop battery and can help you determine if you need to replace it.
