Users of the Microsoft Surface Pro 11 have reported a significant reduction in battery endurance, with some devices now achieving only half their expected runtime. The issue raises from the disappearance of the Battery Limit setting in the UEFI firmware.
Advertisеment
The Battery Limit feature, previously accessible in the UEFI settings, allowed users to cap charge levels at 50%. This option was designed for devices that remain plugged in for extended periods, helping to preserve long-term battery health. Its removal has led to devices charging fully and operating without a charge threshold.
One user noted that the toggle is no longer visible in the UEFI interface. They observed that the device now charges to 100% automatically, even when not connected to power, suggesting an unintended system behavior. This change appears to follow a recent firmware update released last week.
Other users have confirmed similar experiences, including reduced battery longevity and inconsistent charge states. Microsoft has acknowledged the reports and is currently investigating the underlying cause. The issue may stem from a malfunction in the Battery Limit functionality, which affects devices using the Snapdragon X processor.
This feature was available on several Surface models, including the Surface Go (all generations), Surface Pro 7 and later, Surface Laptop 3 and later, Surface Book 3, Surface Laptop Studio (all generations), Surface Laptop Go (all generations), and Surface Laptop SE.
Prior to this issue, the Surface Pro 11 demonstrated strong performance, with tests showing over 10 hours of active use on a single charge. Standby drain was minimal, with less than 2% loss overnight. The current problem is not yet confirmed to affect all units, but ongoing reports indicate it may be widespread.
Microsoft has not provided a timeline for a fix. The company is investigating the issue.
