“Battery Limit” removed from UEFI, but now only charges up to 50%

“Battery Limit” mode has been removed from the UEFI on my Surface Pro (11th edition) and it still only charges up to 50 %. It seems last week there was an update (firmware update?) and the system still seems to be enforcing the 50 % limit automatically based on firmware behavior—even without a visible toggle.

I downloaded the firmeware, but this did not help: Download Surface Pro 11th Edition Drivers and Firmware from Official Microsoft Download Center

Can anyone help?

    Can you all check https://support.microsoft.com/en-us/surface/surface-laptop-7th-edition-update-history-fdadc3d1-87d4-4a58-bc2e-ec9d7e3af16e#cw

    check Windows Update, is new firmware available? report back on status. If there is new firmware install it. Restart. Check the Microsoft Store for a new version of the Surface App. Do you see the new feature ? If you do, can you use the Surface app to change it to 100 % and does that get you out of stuck at 50?

    Thank you for reporting this issue. A software fix that restores the Battery Limit setting to the UEFI is available for Surface Pro (11th Edition) and Surface Laptop (7th Edition) through Windows Update. For more information about how to get updates for your Surface through Windows Update, go to Surface Pro (11th Edition) update history or Surface Laptop (7th Edition).

    Learn more about the Battery Limit setting.

    Smart charging is also available to manage battery life on devices that do not need to use the Battery Limit feature.

    I have exactly the same issue as well, 50% uefi limit was on, now the toggle is gone and I cannot get the device to charge past 50%.

    I have raised something in feedback hub:

    This is a serious problem introduced by MS, and renders our laptops near un-usable on the go, which is the whole reason for getting them in the first place! MS has been very slow in fixing this, pretty unacceptable.

    I’d like to add my experience to this thread regarding the removal of the 50% "Battery Limit" toggle on the Surface Laptop 7th Edition.

    Yesterday, I spoke with Microsoft’s support team to escalate the issue. I explained that the “Battery Limit” toggle had disappeared from the UEFI following a recent firmware update, and despite multiple troubleshooting steps, the device remains capped at 50% charge. The support agent confirmed that this behavior is now firmware-enforced and acknowledged the toggle's removal, but they were unable to offer a workaround or timeline for resolution. They simply stated that they are working to resolve the issue.

    I will submit a Feedback Hub report and encourage others to do the same. Microsoft needs to hear from more affected users to prioritise a fix. If anyone has received different guidance or found a workaround, please share.

    Frankly, I’m surprised by the lack of urgency around what feels like a glaring and crippling technical misstep.

    This behavior on the Surface Pro (11th edition) is actually expected after recent firmware changes. Microsoft removed the manual Battery Limit toggle from UEFI, but the feature itself hasn’t disappeared—it is now managed automatically by firmware and Windows based on usage patterns.

    A few things you can try:

    Check Surface App (Windows Store)

    Open the Surface app and go to Device Information → Battery Settings.

      On newer models, the 50% charge cap is shown there as *“Battery Smart Charging”*. You should be able to turn it off manually.

  
  **Turn off Smart Charging**

  
     If the Surface app shows *“Battery Smart Charging”*, disable it.

     
        Sometimes you may need to plug in the device, leave it idle, and then toggle the setting for it to take effect.

        
        **Update Windows & Surface drivers**

        
           Ensure you’ve installed all updates via **Windows Update** (not just the firmware package from Microsoft’s site).

           
              Often, driver + firmware + OS updates must match to expose the correct UI options.

              
              **Reset Embedded Controller (EC)**

              
                 Shut down your Surface completely.

                 
                    Hold **Volume Up + Power** for about 15 seconds until the UEFI menu opens.

                    
                       Exit without changing anything. This forces the EC to reset and can clear odd charging limits.

                       
                       **If nothing helps**

                       
                          Unfortunately, if the firmware is enforcing the 50% cap, and the Surface app doesn’t let you toggle it, this may be by design in the latest update (to extend battery health). In that case, you may need to wait for a Microsoft patch or contact Surface Support.
