How to Calibrate Battery in Windows 10?

Sudden shutdowns without apparent reason are often a sign that you need to calibrate the battery inside your laptop. Every computer has a built-in battery controller that estimates how much juice inside the battery is. Windows uses that controller to display the charge level in the bottom-right corner of the screen. Sometimes the controller can go wrong and start showing inaccurate values. It does not mean you need to replace a controller or battery right away. The first thing you need to do is calibrate battery in Windows 10.

Before you start, it is important to note that battery calibration in Windows 10 does not magically give you a few more hours of charge. It just forces your laptop to show more accurate values. Also, note that battery calibration does not require additional hardware, nor it harms your computer. In a nutshell, battery calibration is a natural process of fully discharging and fully charging a battery inside your PC.

Tip. Abnormal shutdowns and poor battery life may be signs of an aging and degrading battery. We recommend you create a battery report in Windows to determine whether it is time to replace a battery.

Also, replace the battery immediately if you have spotted swelling, disintegrating, or other signs of physical damage and degradation. Lithium batteries are inflammable and even explosive when damaged. In such a scenario, calibrating the battery in Windows 10 will not help. Replacing the battery is the only option.

Laptop Battery Calibration: How Often Should I Do That?

It all depends on how you use your computer. If you do not allow your battery to charge more than 90-95%, you should perform battery calibration every three to four months. In addition, you can calibrate a battery in a Windows PC every time you notice anomalies in its functioning. Again, battery calibration does not cause any harm, so it is safe to do it whenever you want.

Note that battery calibration in Windows 10 is required mostly for old laptops. Modern computers have a more sophisticated firmware that takes care of battery health. Also, Macbooks with non-removable batteries do not need calibration at all. Still, even if you use a relatively new computer, laptop battery calibration in Windows 10 is a good procedure to ensure everything works as it should.

Tip. Some manufacturers offer battery calibration tools for their laptops. We recommend checking your OEM’s official website for such a tool. Also, some manufacturers provide specific calibration procedures. Follow those instructions to get the best result.

We also recommend checking the BIOS settings or utilities for managing various power settings inside your laptop. Surface devices, for example, have a special mode inside their BIOS that helps preserve the battery when you use a computer plugged in all the time. Tools and modes for limiting the maximum charge are extremely effective ways to prolong the battery life.
