A typical laptop battery becomes weakened over time. This is especially common to laptops that are used rigorously on a daily basis. One key indicator of a weakening laptop battery is the discrepancy between battery life readings and actual battery life.
To correct this discrepancy and prolong the lifespan of your battery, the simple solution is battery calibration. And we’ll be showing you how to calibrate laptop battery in this article.
However, a weakened laptop battery (that has not been calibrated) could cause serious confusion. For instance, on a typical laptop, the remaining battery life could read 2 hours, which, in actual sense, is only 30 minutes or thereabout.
Hence, while your laptop battery is showing you “2 hours remaining”, you get stunned after only 30 minutes – when your battery suddenly drops to 10%, and eventually powers off.
To avoid such confusion and ensure accurate readings of battery life (on a laptop), the ultimate solution is to calibrate your laptop battery.
Follow this article, as Windows Report team provides you with tips, tricks and software solutions, which can be employed to calibrate Windows 10 laptop battery.
Steps to calibrate Windows 10 laptop battery
Some high-performance laptops come with built-in battery calibration tool, which can easily be used to calibrate laptop battery. However, a number (in fact majority) of laptop brands are not equipped with this calibration tool.
Nevertheless, there is no cause for worry, as there is a simple trick you can adopt to manually calibrate your laptop battery, and boost its lifespan.
How can I calibrate my laptop battery? There are three solutions that you can use to calibrate your laptop battery: manually, using BIOS or using third-party software.
For convenience, we’ll be showing you how to execute this manual calibration, in the next section of this article.
Calibrate Laptop Battery Manually
Note: This guide is exclusively meant for Windows laptops.
Modify Your Power Settings
To manually calibrate a laptop battery, the first line of action entails changing the laptop‘s power settings. At this point, you would be required to change the power settings; to prevent your laptop from automatically going into sleep/hibernation/power saving mode, after few minutes of inactivity.
To change the power settings on Windows 10 laptop, follow the steps below:
- Navigate to the taskbar on your screen display, and right-click on “Battery”
- Select “Power Options”
- Under “Power Options”, select “Change when the computer sleeps”
- Click on the “Turn off the display” drop-down and select “Never”
- Click on the “Put the computer to sleep” drop-down menu
- Select “Never”
- Punch the “Change Advanced power setting” key
- Click on the “+” (expand) symbol beside “Battery”
- Click on the “+” (expand) icon beside “Critical battery action”.
- Select “Hibernate”
- Select the “+” icon (expand) beside “Critical battery level”
- Under “On Battery”, select “Percentage”
- Set the percentage to a low value: 1% to 5%.
- Click “Apply” at the lower right-hand corner of your screen
- Select “OK” > “Save Changes”
Once you’ve changed the power settings as appropriate, move to the next stage.
Connect Your Charger
Connect your charger, and juice-up the battery until it’s fully charged. Leave the charger plugged in (after the battery is fully charged) for a few minutes or hours (to enable it cool down).
Disconnect Your Charger
Remove the charger from your laptop and allow the battery to drain down (discharge). Once the battery is completely drained, your laptop will go into hibernation or completely power off.
Reconnect Your Charger
Reconnect your charger, and charge up the battery up to 100% again.
Note: You can use your computer during the recharge process, but it is better you leave it undisturbed
Once your laptop becomes fully charged, the manual calibration process is complete. Your laptop should now show normal battery life readings.
After the whole process, you can reset your laptop‘s power settings (back to the original settings), or if you like, you can leave it as it is.
Calibrate Laptop Battery Using BIOS
Some Windows laptops come with pre-installed battery calibration program, which is embedded in their BIOS. However, a number of laptop brands are not equipped with such program.
So, if your laptop has a built-in Battery Calibration program (in its BIOS), follow the guidelines below to calibrate your battery:
- Power off your laptop and power it on again.
- Enter the BIOS by pressing the “F2” key at the boot menu.
- Using the keyboard cursor keys, select the “Power” menu.
- Navigate to “Start Battery Calibration” and click on the “Enter” key (this action will change your screen background to blue).
- Follow the on-screen command and plug in your laptop charger.
- Once your laptop‘s fully charged (100%), disconnect the charger.
- Allow the battery to drain (discharge) from 100% to 0%; until it automatically powers off.
- Reconnect the charger (do not boot your system while it is charging).
- Once it’s fully charged, the calibration process is complete.
- You can then unplug the charger and reboot your system.
Calibrate Laptop Battery Using Third-party Software
There are special software solutions, exclusively designed for calibrating laptop batteries. In this section of the article, we will be looking at two prominent battery calibration software that are compatible with Windows 10 laptops.
- Smarter Battery
Smarter Battery is a popular battery utility solution for Windows laptops. It hosts a set of energy/power management features, aimed at improving the overall performance and lifespan of laptop batteries. This utility tool is one of the most used third party solutions for calibrating laptop battery.
Some of its key features include Battery Calibration, Alarms, Battery Capacity (remaining battery) display, Discharge (cycle) Count, Green Mode functions, Fast Discharge and more. The battery calibration feature is specially optimized (in the latest update) to perform better on Windows 10 laptops.

Smarter Battery is available at a starting price of $14. However, you can use it on free trial for 10 days.
BatteryCare is another popular battery calibration software for Windows laptops. It can be employed to speed up the discharge process of a laptop battery, so as to facilitate its calibration. This software is compatible with, not only Windows 10, but also Windows 8/1/8/7/Vista/XP.
Also, BatteryCare is very easy to set-up; once you’ve downloaded and installed the program on your laptop, you can easily run it to calibrate the laptop battery.
Aside battery calibration. BatteryCare provides up-to-date information about battery performance. As such, you are always in the know about the condition of your laptop battery.
BatteryCare is a freeware, which means it is offered at absolutely no cost.
No matter how strong your laptop battery is, it will eventually become weakened, with time. The battery weakening process is gradual, such that you’ll hardly notice. At this point, battery life readings suddenly become inaccurate, throwing you into a state of confusion.
To prevent/avoid such situation, you have to calibrate your laptop battery, preferably once in every 2/3 months. And we have described, comprehensively, how to calibrate laptop battery in this article.
