The new feature, called Adaptive Energy Saver, could make a significant difference for anyone who depends on their laptop to stay productive throughout the day.
Right now, Windows only activates its energy-saving mode once your battery hits a low percentage (which you can customize). But Adaptive Energy Saver takes a far more intelligent approach. Instead of waiting for your battery to drop, your laptop observes what you’re doing. If you’re performing light tasks—checking email, browsing the web, working on documents—it automatically switches on energy saver behind the scenes.
And here’s the best part: Microsoft says this won’t constantly dim or brighten your screen. Nobody wants the distraction of shifting brightness levels. Instead, the feature focuses on reducing power usage from components like your CPU and graphics chip when they’re not under heavy load. Since these two components consume the most energy, easing off them can dramatically help extend the life of your laptop battery over time.
