Are you looking for a laptop with all-day power? Check out the laptops with the best battery life.
Get the Most Battery Life for Your Buck
How long a laptop lasts on its internal battery is one of the most important considerations for PC shoppers. Business travelers and students are often at the mercy of their computer's remaining juice, since so many conference rooms, airplanes, and classrooms are woefully short on accessible power outlets. Just a few years ago, it was necessary to buy and charge an external battery pack to get long battery life, or to insist on a machine with a removable, swappable battery. But today, even many thin ultraportables with sealed-shut chassis show impressive endurance away from an AC outlet.
These recent improvements in laptop battery life are thanks to CPUs and other components that are more power-efficient than ever. (It's not just new battery technology that deserves the credit.) That's especially true of Intel's eighth-generation Core processors, the company's newest mobile chips at this writing. One of them powers the longest-lasting model currently on our list, the Lenovo Yoga 920.
A laptop that can last for more than eight hours without a trip to a power plug should be enough to get you through a day's work, but that's not good enough to make it to the upper echelons today. Each of the laptops and 2-in-1s we've selected lasted for more than 13 hours on our tests, which means that they can survive a full day at the office and still offer plenty of juice for your commute or for watching videos on the couch. (Maybe both.)
In addition to being a critical specification, battery life is one of the toughest to measure. If you're watching movies all day long, you'll get far more unplugged time than someone who's editing images nonstop in Photoshop. We test battery life based on a very specific scenario: watching movies stored locally at 50 percent screen brightness and with airplane mode turned on. If you're frequently performing more CPU-intensive or graphics-hammering tasks, you'll want to shave an hour or two off of our results.
Know Your Form Factor
Our top 10 list is stacked with traditional laptops and convertible designs with 360-degree display hinges. Detachable Windows tablets are underrepresented, and for good reason: There's simply no room for a large battery in such a small enclosure. One notable exception is the Microsoft Surface Book 2, which includes two separate batteries, one in the tablet and one in the keyboard base. Together, they eked out an impressive 17 hours of battery life in our testing, but you'll get far less than that if you're using the tablet by itself.
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.
Want the Best Battery Life? Consider a Mac
Apple's MacBook and MacBook Pro lineups have a reputation for excellent battery endurance, and Cupertino's current offerings are no exception. All of the portable Macs we tested can manage more than 15 hours away from an outlet, from the 15-inch MacBook Pro to the aging-but-still-popular 2017 MacBook Air. Which one you should choose depends on your budget, your portability needs, and your usage patterns, but you can't go wrong on the battery-life front with any Apple ultraportable. (And remember, Macs can run Windows, too.)
Other manufacturers are more hit-and-miss. While the top battery-life honors of the moment go to the Yoga 920, Lenovo also sells several less-expensive models that run down much quicker.
If you have a long plane flight, a conference, or a final-exam period ahead of you, or if you're just too busy to linger around a power outlet for long enough, any of these laptops will keep you productive throughout the day and into the evening.
