Assume that your Surface device has to be plugged in for extended periods of time. For example, you are using a Surface Kiosk. In this scenario, it is important to adjust the battery charging for optimal performance.
To support Kiosk scenarios, the Surface firmware is getting updated to add a Kiosk mode. This mode allows configuration of battery limits through a Battery Limit setting.
Support for this feature is in the Unified Extensible Firmware Interface (UEFI) settings. You can enable Battery Limit through UEFI or through Microsoft Surface Enterprise Management Mode (SEMM).
The following bullets list the devices and firmware versions (some with needed updates) that support this feature:
- Surface Pro 3 - September 10, 2018 update. UEFI version: 3.11.2550.0, EC version: 22.214.171.124 and later versions.
