1] Run the Power Troubleshooter

The Windows Power troubleshooter can identify and resolve issues with power settings, increase battery life, etc., and it has helped many users fix the issue of their laptops displaying the wrong battery percentage. Your laptop’s power management settings will be optimized, and any necessary adjustments will be made. So, this is how you go about it:

  • On your Windows laptop, open Settings and click on the System option on the left pane. Scroll down and click on the Troubleshoot option on the right.

From Windows Settings Choose Troubleshoot

  • From the Troubleshoot page, click on Other troubleshooters.
  • On the next page, scroll down and locate Power troubleshooter. Click on the Run button next to it.

Run the Power Troubleshooter

The troubleshooter will now look for several problems with the power plan, display brightness setting, minimum processor state, wireless adapter setting optimized for power saving, etc.; if problems are detected, it will automatically repair them.

You can close the windows and check whether the battery percentage is displayed correctly or not.

2] Perform a Power Cycle to Clear Residual Charge

A power cycle will clear any remaining charge from the laptop’s capacitor and fix any associated issues. This should solve the problem and save you a lot of time if the inaccurate battery percentage on Windows is an occasional or one-off glitch. Let us see how to perform a power cycle:

  • Start by pressing your laptop’s power button to shut down your laptop and unplug any external devices connected to it.
  • Take the laptop’s battery out. Then, hold down the power button firmly for 15 to 20 seconds. It will drain any remaining charge from the internals of your laptop.
  • After a minute, reinstall the battery and turn on your laptop. Check to see if Windows shows the correct battery percentage after that.

3] Calibrate Your Laptop Battery

Another solution to fix incorrect battery readings on your laptop is to calibrate the battery. You must first modify the power management settings, so they do not obstruct the battery calibration procedure before that. So, this is how you go about it:

  • Press the Windows key + R to open the Run dialog box. Type powercfg.cpl and press OK.

Open Power Options Through Run Prompt

Choose Change When The Computer Sleeps Option

  • Click on all four drop-down menus and choose the option Never. Next, click the Change advanced power settings option on the same page.

Change Sleepand Display Settings To Never and Change Sdvanced Power Settings

  • Scroll down, locate the Battery option, expand it, and double-click on Critical battery action. Click on the drop-down boxes next to the On battery and Plugged in options and choose the Hibernate option for both.

Change Critical Battery Action To Hibernate

  • Next, scroll down and double-click on the Critical battery level option and use the drop-downs to set the values to as low as 5 percent. Press Apply and then OK to save the changes.

Change Critical Battery Level To The Lowest

  • The next step is to calibrate your laptop battery by following the instructions below after configuring the power management settings given above. This is how you go about it:
  • Charge your laptop battery fully (100 %) and leave the charger plugged in for a few hours.
  • Start using your laptop after unplugging it. Allow your laptop to run out of charge and shut down independently entirely.
  • After your laptop shuts down, plug in the charger and allow it to get charged to 100 % again.

Your Windows laptop should then display the correct battery readings.

4] Enable Battery Adapter via Device Manager

Your computer’s battery adapter serves as a communication link between Windows and the battery in your laptop. If there are problems with this adapter, Windows might be unable to gather the necessary information and display the wrong battery level. Here is how to fix it.

  • Open Device Manager and expand the Batteries option. Right-click on the Microsoft AC Adapter option and click on the Disable Device option from the context menu.

Disable Battery Adapter From Disk Manager

  • Right-click on the battery adapter again and click on the Enable Device option.

Enable Battery Adapter From Disk Manager

  • After you are done, restart your device to apply the changes and check whether the battery percentage displays correctly.

If none of these methods helped you resolve the issue, there might be a problem with your laptop’s battery.
