How to Calibrate Battery in Windows 10?

Sudden shutdowns without apparent reason are often a sign that you need laptop battery calibration. Every computer has a built-in battery controller for managing charging, calculating remaining battery level and time, preventing the battery from overheating, etc. Windows uses that controller to display the charge level in the bottom-right corner of the screen and shutdown your computer when the battery reaches critical levels. Sometimes the controller can go wrong due to a bug or aging and start reporting inaccurate values. It does not mean that you need to replace the controller or battery right away. The first thing you need to do is calibrate battery in Windows 10. This is a universal guide describing laptop battery calibration, and it works in both Windows 10 and 11.

Before you start, it is important to note that battery calibration in Windows 10 and 11 will not magically give you few more hours of charge. It just forces your laptop to show more accurate values. Battery calibration cannot fix your dying battery or reverse its aging process. 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 to bring the controller to its senses.

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

Also, replace the battery immediately if you see swelling, disintegrating, or other signs of physical damage and degradation. Lithium batteries are inflammable and even explosive when damaged and exposed to air. In such scenario, calibrating the battery in Windows 10 will not help. Replacing the battery is your only option. If you do not know how to safely replace the battery in your laptop, contact your local repair shop immediately.

Laptop Battery Calibration—How Often Should I Calibrate Battery in Windows?

It all depends on how you use your computer. If you do not allow your battery to charge more than 90-95%, perform battery calibration every three to four months. Also, you can calibrate the battery every time you notice anomalies in its behavior. Again, battery calibration does not cause any harm, so it is safe to do it whenever you want. We do not recommend doing it too often since frequent discharges to the total zero speed up battery aging.

Note that battery calibration in Windows 10 and 11 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.

Calibrate Battery on Windows 11

Calibrating laptop battery in Windows 11 works the same way as in Windows 10. The only difference is that Windows 11 has a slightly different Settings app, so here is how to access the settings you need to calibrate laptop battery in Windows 11:

  1. Charge your laptop to 100% and leave it plugged in for an hour or two. This will ensure that the battery is fully charged in case your laptop incorrectly reports the 100% level. It will also allow the battery to cooldown.
  2. Right-click the Start menu and select Power Options. battery calibration software windows 10
  3. Expand the Screen and Sleep section. laptop battery calibration software
  4. Set all four options to Never. Windows 11 will warn you that disabling sleep will increase carbon emissions. You can ignore that message, but be sure to restore the previous settings once the calibration is complete. calibrate battery laptop
