Smarter Battery Life for Windows 11 Laptops

Nov 2025

When was the last time you wrapped up a busy day and still had plenty of battery left on your laptop? For most people, that’s unusual.

Microsoft is working to change that with a new Windows 11 feature designed to make your laptop battery last longer.

It’s called adaptive energy saver, and it could be a real game-changer for business users.

Until now, Windows has only switched on energy saver mode when your battery level dropped to a certain percentage. You could set that threshold yourself, but the system was still reactive rather than proactive.

Adaptive energy saver works differently. Instead of waiting for your battery to run low, it constantly monitors how you’re using your device. If you’re carrying out lighter tasks such as browsing the web, replying to emails, or writing in Word, Windows automatically enables energy saver quietly in the background.

Unlike older power-saving modes, this feature doesn’t dim your display. Instead, it focuses on reducing the workload of major power-hungry components like your processor and graphics chip when they’re not needed. By easing the strain on these parts, your laptop could run for much longer before you need to reach for a charger.

For now, adaptive energy saver won’t be switched on automatically. You’ll need to activate it manually in your system settings.

It’s still being tested in Microsoft’s Canary channel, where experimental features are trialled before being released to all users. There’s no guarantee it will make it to the final version of Windows 11, but the potential benefits make it worth watching closely.

For businesses, the benefits go beyond convenience. Longer battery life means employees can work uninterrupted, whether they’re in client meetings, travelling between sites, or working remotely from another location.

Fewer interruptions lead to smoother workflows and less stress. Over time, greater battery efficiency can even help extend the overall lifespan of your laptops by reducing how often they’re fully discharged and recharged.

At Affinity, we’re always looking for technology updates that make a genuine difference to day-to-day productivity. Adaptive energy saver feels like one of those improvements that delivers exactly that.

It’s still early days, but if Microsoft rolls this out more widely, many Windows 11 laptops could feel like they’ve had a major upgrade, without the need to buy new devices.
