This is way more power-efficient than the Surface Pro 9 WiFi, especially in the normal web surfing test. But against the Surface Pro 11, it's still not as power-efficient. Moreover, despite almost identical battery capacity as the Surface Pro 11 X Plus, it couldn't manage longer web surfing. Perhaps the recently launched Intel Core Ultra 200V series could show the power consumption of the Snapdragon X Plus/Elite level, but only time will tell. For now, the Surface Pro 11 is still my choice.
