Microsoft has released new firmware updates for the Surface Pro 11 and Surface Laptop 7 with Snapdragon processors that introduces a new feature that was previously only available on the Intel models and new Surface Pro 12-inch and Surface Laptop 13-inch — the ability to customize the battery charge limit feature directly from inside the Surface app.
Up until now, the Surface Pro 11 and Surface Laptop 7 with Snapdragon have included a feature called smart charging, which would dynamically enable a battery charge limit based on how often your device was plugged in. Unfortunately, it was not possible to override this from within Windows. The UEFI did have an option to enable and disable a 50% charge limit.
