Our top-laptops list is stacked with traditional laptops and convertible designs with 360-degree display hinges. Detachable Windows tablets tend to be underrepresented, and for good reason: There's simply no room for a large battery in such a small enclosure. The best of these, like Microsoft's Intel-based Surface Pro 9, tend to run around 12 hours. "Traditional laptops" doesn't always mean big laptops, though: You will find plenty of these laptop and convertible picks to be relatively thin and light. Advancements in chassis design, Windows settings, and processor architecture allow for thin-and-light laptops to squeeze more life out of their batteries than ever. A long-lasting battery absolutely doesn't have to mean a big laptop. Of course, no matter what kind of laptop you're in the market for, you can always add a few minutes or a few hours to your unplugged time by changing your computing habits. It's a bit like driving more conservatively to save gas. For some ideas, take a look at our tips for improving your laptop's battery life.
