To quantify the degree of wear on your device’s battery, you can check its battery cycle. Let’s see how to run a battery cycle count on your Windows laptop to keep an eye on its health.
What Is a Battery Cycle Count?
Battery cycling simply means that the battery is fully discharged, from 100% to 0%. This need not happen at the same time. For example, if your laptop battery is depleted from 100% to 50%, then you charge it to 100% and then reduce it to 50%, which counts as a cycle.
The number of battery cycles is the number of battery cycles. The lower the laptop battery cycle, the more “healthy” the battery. Compared to a heavily used battery, a healthy battery will stay near its maximum charge when it leaves the factory.
Fortunately, Windows gives you an easy way to check your laptop’s battery cycle times. Whether you want to know how long your battery has worked over the years or you want to check out a used machine before you buy it, you can run a quick command to find this information.
The number of cycles required to “drain” the battery depends on the specific battery in the laptop. Most batteries can operate for at least 500 cycles. In contrast, Apple rates its modern MacBook models as continuous 1000 cycles. After these points, the battery should still work, but it will have much less power.
How to Check the Battery Cycle Count on Windows 10
On a Windows laptop, you can check your computer’s battery cycle count using a quick Command Prompt command. To open the Command Prompt, right-click on the Start button (or press Win + X) and choose Command Prompt or Windows PowerShell from the menu that appears.
When you see the Command Prompt, type this command:
Next, head to your user folder in the File Explorer app and look for battery-report.html at this location, which will also display in the Command Prompt window:
Double-click on this file and it should open in your default browser. At the top, you’ll see some basic information like your PC name and when the report ran. Scroll down to find the Installed batteries section, and you’ll see the Design Capacity and Full Charge Capacity.
The design capacity is the initial maximum charge of the battery, and the full charge capacity is the amount of power that the laptop battery can now hold. If these two numbers are close enough, then your battery is good. However, if the total charging capacity is much smaller than the design capacity, the health of the battery has been significantly reduced.
The cycle counter shows the number of times the battery has been charged. If there are more cycles, your maximum capacity may be lower than the original level.
Below this, you will see information about recent battery usage, which can be helpful if you need to troubleshoot a specific issue. For more information, check out some Windows applications for analyzing laptop battery life.
No Cycle Count in the Windows Battery Report?
It is possible that when you generate a battery report in Windows, it does not actually include the cycle count. You can see this in the image above, it only shows a dash instead of the correct number.
If you encounter this situation, first make sure that you have updated all the drivers for your computer. This problem occurs when Windows cannot properly interact with your computer hardware, which means that the current driver is important.
Pay special attention to the battery controller and chipset controller. After installing the available updates, restart the computer and try to run the battery report again. If it fails, it is best to update your UEFI/BIOS.
If the BIOS and driver updates do not work, you should try to install the PC management software provided by the notebook manufacturer. For example, on a Lenovo machine, you can install Lenovo Vantage.
In addition to useful functions such as updating drivers, these applications can also display system information. Look for sections about system status, battery management, hardware details, or similar content. It should contain information about your battery; hopefully it will also include the correct battery cycle count.
Know Your Laptop’s Battery Cycle Count
Now you know how to check the laptop battery cycle number to see if the battery is good. Don’t worry too much about the battery cycle; Using batteries is a natural part of owning a laptop. In many cases, you can replace the battery with a reasonable charge and it will continue to work after a certain number of cycles. You just need to charge more often.
At the same time, taking basic power-saving measures, such as reducing the brightness, will help reduce the amount of power consumed by the laptop, slowing down the number of battery cycles you experience over time. It is advisable to keep the battery like this, especially if it is not removable.
