Windows 10 Powercfg Energy Report Can Be Used To Analyze Battery And Fix Battery Health [Learn How To]
Windows 10 is an amazing operating system, and it does a great job of ensuring that you get stable battery life. However, some Windows 10 laptop users complain that the battery life drains very quickly sometimes. This can be due to multiple factors, and you can check for these factors and fix these problems very easily. Windows 10 powercfg battery report and Windows 10 powercfg energy report can help you identify these issues and fix them.
Windows 10 Powercfg Energy Report - Step-by-Step Tutorial
The powercfg battery report is essentially a battery health check. The powercfg energy report tests battery life factors and reports any errors in your hardware or software that may harm your battery life. This tutorial will show you step-by-step how to check Windows 10 laptop battery life with the powercfg energy report.
Create Report With Command Prompt
Step-1: To ensure that you get the best results, first close down all other running applications.
Step-2: Go to the Start Menu and type cmd in the search bar. Click on Run as administrator.
Step-3: Once you do, you will get a message asking, ‘Do you want to allow this app to make changes to your device?’ Click Yes.
Step-4: Type powercfg/energy and click Enter.
This command runs a scan for 60 seconds and identifies issues, if any. If there are issues, you will be told that Energy efficiency problems are found. Some would be errors, some earnings, and some informational. There is also the possibility that no issues will be found, and the problem lies with your battery itself. This is what the command prompt will look like in case of issues:
If you are not satisfied with the report, you can run the energy scan for a little longer.
Step-5 (optional step): Type the command powercfg /energy /duration 120 and press Enter.
[Keep in mind: The way to correctly enter the command is to copy-paste the command I gave above, or if you type manually, ensure that the spaces are in the correct places. There is a space after you type powercfg, after energy, and after duration.]
The 120 represents the number of seconds the scan will run. You can increase or reduce this number. But if you run the scan for a very long period of time, it is possible that the scan will give you a lower and lower number of issues and won’t benefit you.
Review Energy Report
The energy report is a little technical, and some information may be a little hard to decipher. No need to worry because I will show you what you should be looking for to ensure a healthy laptop battery life.
Step-1: When you ran the command, you may have noticed that the command prompt also gives you the location of the energy report. The location is the same for you and me. You can copy that location and post it in your browser, or you can copy the command below as well. I repeat, the location will be the same.
Step-2: The first part of the report shows your laptop name, scan time duration, manufacturer details, BIOS version, OS build, etc. You can check if your BIOS is up to date or not by checking it against the manufacturer’s site. You can also update your Windows version if you see that it isn't up to date.
Step-3: The first section of the analysis part of the report is about any Errors found. You should be on the lookout for three things:
a) Device Drivers
b) CPU Utilization
c) Applications that are stopping the computer from sleeping
[As you can see in the snippet below, I do not have driver issues and applications that are stopping my computer from sleeping]
You will have to address each issue individually. If your drivers are not up to date, you may have to update them. Some drivers may need reconfiguration.
With CPU utilization, you will have to check for startup apps, background apps, and other services that may be draining your battery life.
Step-4: The next section is the Warnings section. The section points towards the features that are not using the recommended Windows 10 battery settings. If you followed my recommendation and closed all the applications before running the energy scan but you still an application is running and consuming power, there is a possibility that you may have a virus or malware. Run a malware scan immediately. [I did not close my applications before running the scan; hence, I have a lot of warnings]
Step-5: The last section is the Information section. As the name suggests, this section gives you a lot of detail about your battery brand, capacity, power settings, policies, etc.
It has a lot of detail, so I will tell you, one by one, what the section entails.
a) The Power Policy section lists your settings when you are plugged into power and using battery power. You can adjust the settings as you see fit.
b) After this, you will see the battery information section, which shows you what capacity your battery is. It also shows you what capacity it had when you last charged it. If these two numbers are different, you may want to run a battery health report.
c) Another section that you should look at is the Platform Power Management Capabilities. This section shows you what your system is doing to ensure that you have optimal battery life.
Other things mentioned in this section are the sleep states supported by your device and connected standby support.
You can run the report and look throw all the errors, warnings, and information to get a cursory idea about your battery life. If you don’t like your present settings, you can change them. If you find drivers missing, you can install them, and you close down the background apps and services that are draining your battery life. This report will help you fix problems you may not know your Windows 10 laptop battery had. So, use it well.
