How To Fix Laptop Showing Wrong Battery Percentage on Windows 11

Fed up with your laptop showing wrong the battery percentage on Windows 11?

Laptops display an estimated battery time that’s determined by your computer usage. And for those who aren’t aware, there are a lot of factors to why your laptop’s battery drains faster than normal. Good example of this is setting the screen to full brightness, as well as video streaming, and playing video games for long periods of time.

But if you tend to use programs like Word, Mail, etc., your computer’s battery life should also increase. However, if that is not the case, you could be facing serious issues with your laptop’s battery. And we will be addressing the solutions to this problem below.

So, what’s the delay for? Let’s jump right in!

1. Perform a Power Cycle.

We’ll start by power cycling your laptop to resolve its battery-related issues. By doing this, you clear out your laptop’s internal memory, as well as remove the residual charge from the battery’s capacitor. With it, you even get rid of the potential bugs or glitches from the system.

Here’s what you’ll need to do:

1. First, press the Power button to power off your computer.
2. Then, remove all peripherals.
3. After that, take out your laptop’s battery.
4. Next, press and hold down the Power button for around 30 seconds.
5. After some time, put the battery back in its place.
6. Then, turn on your computer.

Now, check to see if the correct battery percentage is showing or not.

2. Run the Power Troubleshooter.

If this issue is really caused by battery-issues in your computer’s system, then this method will definitely prove useful. The built-in troubleshooter helps diagnose the problematic area and resolves this problem.

Use the steps below:

1. Go to the Search icon from the taskbar.
2. Type Troubleshoot settings in the search bar.
3. Then, click on Open from the right pane.
4. Select the Other troubleshooters option.
5. Next, scroll down and locate Power. Then, click on Run next to it.

Once you’ve run the troubleshooter, check the battery percentage again if it’s accurate.

3. Calibrate Your Laptop Battery.

Calibrating your computer’s battery is another option to rectify incorrect battery estimate. This is where you charge the battery to its full capacity, then run it down to zero and back to 100% again.

But before that, you’ll need to head over to the battery management options and ensure that the power plan doesn’t interfere with the calibration process. Follow the steps below to do so:

1. Press the Windows + R keys to launch the Run dialog box.
2. Then, type powercfg.cpl in the text field.
3. Click on the OK button.
4. Next, from the left pane, select the Change when the computer sleeps link.
5. Choose Never for every drop-down menu.
6. Then, click on the Change advanced power settings option.

7. Expand the Battery option, then double-click on Critical battery action.
8. Now, select Hibernate for both On battery and Plugged in options.

9. Then, double-click the Critical battery level option.
10. Next, set On battery and Plugged in to low values.

11. After that, click on the Apply button.
12. Then, click on OK to confirm the changes.

Now that you’ve done the primary steps, you may now calibrate your battery. You can do so by following these methods:

1. Fully charge your laptop and keep the charger plugged in for several hours.
2. Then, unplug the charger and use your laptop until the battery drains out. This will cause the laptop to power off.
3. Now, replug in the charger and let your laptop charge fully.

After this, your laptop should show accurate battery percentage readings.

4. Restart Battery Adapter.

The battery adapter is the bridge between your Windows and your computer’s battery. Any problem in the adapter will cause incorrect battery percentage estimates.

You can try disabling and re-enabling the battery adapter to see if that resolves the issue. Follow the steps below to do so:

1. Press the Windows + S shortcut keys to launch Windows Search.
2. Search for Device Manager and press the Enter key.
3. Now, look for the Batteries value and click on it to expand it.
4. Then, right-click your battery adapter and choose the Disable device option from the menu.

5. Right-click your battery adapter again, and this time click on Enable device.
6. Restart your computer.

Once the computer restarts, check if the battery error is now fixed.

5. Repair Battery Drivers.

If the drivers are missing or have damaged, restarting them would be useless. And to fix that, you’ll need to either update the dedicated drivers’ versions or reinstall them.

To update the drivers, here’s what you must do:

1. First, right-click on the Start menu from the taskbar.
2. Then, select Device Manager from the list of options.
3. Click on Batteries to expand it.
4. Now, right-click on your battery adapter and choose the Update driver option.

5. Then, follow the on-screen instructions to update the driver.

For corrupted drivers, you can uninstall them from your system. Afterwards, restart your computer, and the drivers will reinstall upon boot. Use the instructions below to do so:

1. Click on the Start icon from the taskbar.
2. Search for Device Manager in the search bar and click on
   Open from the right pane.
3. Now, expand Batteries by clicking on it.
4. Right-click on your battery adapter and select Uninstall device.

5. Next, restart your computer to reinstall the driver.

Now, check to see if your laptop will show an accurate battery percentage. If not, try the next method.

6. Update Windows.

Usually, the newer Windows version updates downloads and installs them independently. Although, if you’ve disabled automatic updates on your PC, you must keep your system updated.

The wrong battery percentage display could be due to an outdated Windows version. Therefore, we recommend you install any pending updates to resolve the issue. Here’s how:

1. Start by pressing the Windows + I keys to launch Settings.
2. Next, from the left pane, select Windows Update.
3. Click the Check for updates button on the right side of the screen.
4. If there is any update available, click on Download & Install.

Next, check to see if the correct battery percentage is showing or not after updating windows.

7. Get Your Battery Replaced.

In case none of the methods discussed above were successful in fixing your laptop showing the wrong battery percentage on Windows 11, the issue could be hardware-related. If that’s the case, you should contact your manufacturer and get your battery replaced.
