Battery health is an important metric that can help you know how long the battery in your device will last before it needs replacing. Apple devices like Macbooks, iPads, and iPhones usually have built-in battery health tools that can help you check the battery health quite easily. Unfortunately, if you are a Windows user, you won't find such tools baked into the OS. However, you can still find out the battery health of your Windows laptop in a few ways.

Method 1: Generate a battery report using Command Prompt

Windows 11 lets you generate a comprehensive battery report using Command Prompt, which can provide you with information regarding the battery health of your machine.

  1. Open the Start menu, type cmd, and click on 'Run as administrator'.
  1. When the Command Prompt window opens, type powercfg /batteryreport, and hit Enter.
  1. Your battery life report will be generated and saved to the following path: C:\Windows\System32\battery-report.html.
  1. You can navigate to the System32 folder in your C Drive and open the report using a PDF reader or web browser. The report provides detailed information related to the battery of your Windows machine, such as the battery manufacturer, connected standby, etc.
  1. Scroll down to the 'Installed batteries' section, and you will see the 'Design Capacity' and 'Full Charge Capacity'.
  1. You can calculate the battery health of your device using the following formula:

Battery Health(%)=(Full Charge Capacity/Design Capacity​)×100

By using the above formula, we get: Battery health = (33,242/41,998) x 100 = 79%.

Note: You can also use the same command in Windows PowerShell to generate a battery report in the same manner. In this case, the report will be saved in C:/Users/YourUsername. You can then calculate the battery health as explained above.

Method 2: Use manufacturer-provided tools

Manufacturers like Dell, HP, and Lenovo often provide tools that can help you check the battery health of your Windows 11 laptop. On Dell laptops, you get the Dell Power Manager tool, which lets you know the condition of your battery.

  1. If you don't already have Dell Power Manager installed on your Dell laptop, you can get it from Dell's official website.
  2. Once it is downloaded, install Dell Power Manager and open it from the Start menu.
  1. When the Power Manager opens, move your cursor to the heart icon at the top right. The program will let you know about your battery health and will also inform you if you need to get the battery of your laptop replaced.
Note: Dell also offers other tools like Dell Optimizer and On-Board Diagnostics that can help you check the battery health of your laptop. However, not all tools are present on all laptops from the brand.
  1. You can find similar battery health tools on laptops from brands like Lenovo and HP. If you have an HP laptop, you can visit this page and use the Battery Check utility to get details about the battery health of your Windows machine.
  2. Similarly, Lenovo users can use the Lenovo Vantage application to check the battery health of their Windows machines.

Method 3: Check the battery health from the BIOS/UEFI

On certain laptop models from some brands, you can also check the battery health of your laptop from the BIOS/UEFI.

  1. Restart your laptop and press the F2 key multiple times to enter the BIOS/UEFI.
  2. Go to the 'General' or 'Overview' section and look for the battery health option. Here, you can check the health status of the battery and find out if it needs replacing.

Method 4: Use BatteryInfoView to check the battery health

Third-party tools like BatteryInfoView can provide information regarding the battery health of your laptop.

  1. Visit this website and download the 32-bit or 64-bit version of BatteryInfoView, depending on your system.
  1. Once the .zip file is downloaded, extract it and run BatteryInfoView.exe.
  1. You should see the battery health mentioned along with other battery-related information in the program.
