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.
