What You Need

  • Access to Windows Terminal as an Administrator on Windows 11

Windows makes that easy. You'll just need to generate a battery health report by using Windows Terminal or Windows PowerShell, and then find the report in your system files. You also can download an app from the Microsoft Store that will visualize battery health data for you in a more friendly way.

How to check your battery health using Windows Terminal

The suggested way to see battery health percentages in Windows 11 is by generating a battery health report. This is done by using Windows Terminal. This method is a bit more technical, but it also is one of the most reliable because it is pulling raw data from your system. Here's how to get started with generating one.

Step 1: Right-click on the Start Button and choose Terminal (Admin)

Step 2: Press Yes to any security prompts. Type the following code, and press Enter:

powercfg /batteryreport /output "C:\battery-report.html"

Step 3: Open File Explorer. Click This PC in the sidebar. Choose Local Disk C. You'll see a battery-report.html file waiting for you.

Step 4: Once you double-click to launch the file, you'll see a few things. The top of the report shows information about your PC. The Installed Batteries section will show you information about the battery and how many times it's been charged. Note down the Cycle Count, which is how many times the battery has gone from 100%-0% and charged fully again. Too many cycles indicates a unhealthy battery.

You'll also want to pay attention to the Design Capacity and the Full Charge Capacity. Design Capacity is the full capacity of your battery. In our case, 56,310 mWh. Full Charge Capacity is the current count of how much charge your battery can currently hold. It degrades overtime. In our case, it has gone down to 47,240 mWh. A significant degradation in capacity means the battery could be getting unhealthy.

Step 5: If you look under Recent Usage, you'll see how your laptop was using battery power up until the report was generated. You'll see the time for each drain. A graph is also available below, to show you how the power has been used over time. Usage History under this same area will show how the system used the battery over time.

Step 6: There's also the battery capacity history, which shows how the capacity itself has changed. This could point to moments where something you did on your laptop affected its battery health.

Step 7: Finally, there's Battery life estimates. Based on all the factors we mentioned so far, this is how long your laptop's battery will last. You get a full-charge estimate based on the current capacity, and a full-charge estimate based on the designed capacity, as your laptop first shipped.

How to check battery health using Windows Powershell on Windows 10

If you're still running Windows 10, the process of generating a battery report is the same as Windows 11. However, you'll be using Windows PowerShell instead.

Step 1: Right-click on the Start Menu and choose PowerShell (Admin).
