The battery life of a laptop is a vital component, but not one that many people take the time to keep in good condition. Laptop batteries are designed to last between 3-5 hours in normal usage, but if your battery is running low, it’s essential to calibrate the battery to ensure it’s working at its full capacity.
Technically, there are two ways of calibrating a laptop battery for use with Windows 10: using the built-in tools in Windows 10, or using the included Windows 10 Power Profile app. The Power Profile app, as you might expect, displays the battery’s capacities as a percentage, which is great for users who don’t need to be precise. However, if you need to check the exact capacity of the battery, then you will be happy to know that there is an alternative solution: the battery calibration tool in Windows 10.

A normal laptop battery gets weaker over time. This is especially true for laptops, which are used intensively on a daily basis.
One of the main signs of a weakened laptop battery is the difference between the advertised and actual battery life.
A simple solution to overcome this problem and prolong the life of the battery is to calibrate it. In this article, you will learn how to calibrate your laptop’s battery.
However, a weakened laptop battery (that has not been calibrated) can cause serious malfunctions.
For example, on a typical laptop, the remaining battery life may be 2 hours, which in reality is only about 30 minutes.
So if your laptop’s battery says 2 hours left, you’ll be surprised after only 30 minutes when the battery charge suddenly drops to 10% and eventually shuts down.
To avoid this confusion and ensure an accurate reading of the battery life (of your laptop), the ultimate solution is to calibrate your laptop battery.
Follow this article and the Windows Report team will give you tips, recommendations and software solutions for calibrating your Windows 10 laptop’s battery.
Some powerful laptops have a built-in battery calibration tool that allows you to easily calibrate your laptop’s battery.
However, a number (in fact, most) of laptop brands do not come with this calibration tool.
However, you don’t have to worry because there is a simple trick that you can use to manually calibrate your laptop’s battery and extend its life.
There are three ways to calibrate a laptop’s battery: manually, through the BIOS, or with third-party software.
To keep it simple, we will show you how to perform this manual calibration in the next part of this article.
How can I calibrate the battery of my Windows 10 laptop?
1. Manually calibrating the notebook battery
1.1. Changing power settings
- Navigate to the on-screen taskbar and right-click on Battery.
- Select Power Options.
- Under Power Options, select Change the computer’s standby time.
- Click the Disable display drop-down menu and select Never.
- Select the Computer Hibernate drop-down menu and select Never.
- Click the Change advanced power settings button.
- In the battery compartment, press the + icon (magnify).
- Select the + (unfold) icon under the Critical Battery action and select Hibernate.
- Press the + icon (enlarge) under Critical Battery Level.
- Under Battery, select Percentage.
- Set the percentage to a low value: 1% to 5%.
- Click Apply in the lower right corner of the screen.
- Choose OK and save the changes.
To manually calibrate the laptop battery, you must first change the laptop’s power settings.
At this point, you need to change the power settings to prevent the laptop from automatically going into sleep or power saving mode after a few minutes of inactivity.
After changing the power settings as desired, proceed to the next step.
1.2. Connect the charger
Plug in the charger and power the battery until it is fully charged. After the battery is fully charged, leave the charger plugged in for a few minutes or hours (to allow it to cool down).
If you’re looking for a Windows 10 laptop with the best battery on the market, check out our top options.
1.3. Disconnect charger
Remove the charger from the laptop and allow the battery to discharge. When the battery is completely exhausted, the notebook computer goes into sleep mode or shuts down completely.
1.4. Reconnect the charger
Reconnect the charger and recharge the battery to 100%.
Message: You can use the computer while it is charging, but it is best to leave it on.
1.5. Battery calibration
Once the laptop is fully charged, the manual calibration process is complete. Your laptop should now have normal battery life.
After the whole process, you can reset your laptop’s power settings (return to the original settings) or, if you prefer, leave everything as it was.
2. Calibrating the notebook battery via BIOS
- Turn the laptop off and on.
- Enter the BIOS by pressing F2 in the boot menu.
- Use the cursor keys on the keyboard to select the Power menu.
- Go to Start battery calibration and press Enter (the background of the screen turns blue).
- Follow the on-screen instructions to connect the charger to the laptop.
- When the laptop is fully charged (100%), disconnect the charger.
- Allow the battery to discharge from 100% to 0% before turning it off automatically.
- Reconnect the charger (do not start the system while it is charging).
- When fully charged, the calibration process is complete.
- You can then disconnect the charger and restart the system.
Some Windows laptops come pre-installed with a battery calibration program built into the BIOS. However, a number of laptop brands do not have such programs.
So, if your laptop has a built-in battery calibration program (in the BIOS), follow the tips above to calibrate the battery.
Even if you find that the battery level is damaged, you should quickly fix the problem by following our step-by-step guide.
3. Calibrate the notebook battery with a third-party program
There are special software solutions designed exclusively for laptop battery calibration. In this part of the article, we’ll look at two popular battery calibration programs that are compatible with Windows 10 laptops.

No matter how strong your laptop’s battery is, it will weaken over time.
The battery drains gradually, so you hardly notice it. At this point, the battery life display suddenly becomes inaccurate and you become confused.
To avoid this situation, you should calibrate the laptop battery, preferably every 2/3 months. In this article we have described in detail how to calibrate your laptop battery.
We hope these methods for calibrating your Windows 10 laptop battery were helpful. If you have any other suggestions or questions, feel free to ask them in the comments section below.
