Laptops with the Longest Battery Life

No matter how stacked its specs are, a laptop is useless if it can’t hold a charge. Fortunately, there are plenty of notebooks that go the distance. Using our Laptop Mag Battery Test, which involves continuous Web surfing over Wi-Fi at 100 nits of brightness, we’ve identified the longest-lasting notebooks on the market. We’re talking more than 10 hours of endurance, which should more than suffice for that cross-country fight, a long day of meetings or multiple, back-to-back classes.

Lenovo ThinkPad T470 (17:25)

If you want a truly fantastic keyboard, durable chassis and strong performance, look no further than the ThinkPad T470. The T470 makes room for an optional extended battery that gives this 14-inch laptop over 17 hours of endurance (with its non-touch display). You can charge the laptop over a proprietary ThinkPad connector or via its Thunderbolt 3 port, which allows you to juice the laptop and output to multiple monitors over a single wire. A durable, MIL-SPEC-tested chassis helps this long-lasting business notebook stand up to the rigors of all-day business travel.

Apple MacBook Air 13-inch (14:00)

Having debuted in 2015, the 13-inch MacBook Air may be a bit out of date, but it’s still for sale and now an even better value at $899. With a 14-hour runtime, the current Air lasts nearly 2 hours longer than its predecessor and is nearly double the ultraportable category average.

Microsoft Surface Book (12:29)

When coupled with its keyboard dock, Microsoft’s first notebook will last up to 12.5 hours. But this “ultimate laptop” also comes with a clever fulcrum hinge, 13.5-inch, 3000 x 2000-pixel display, and a magnetically attached stylus. All this in a minimalist magnesium chassis that will probably end up in MoMA.

Dell Latitude 7280 (12:29)

With its extended battery on board, the Dell Latitude 7280 lasts for 12 hours and 29 minutes on a charge. This 12-inch laptop has a really light starting weight of 2.8 pounds and a durable MIL-SPEC-tested chassis that can survive drops from up to 30 inches, along with extreme temperatures and pressure.

A luxurious soft-touch deck and deep key travel provide an excellent typing experience while an optional infrared camera lets you log into Windows 10 using facial recognition.

Lenovo Miix 310 (12:24)

Available for under $300, the Lenovo Miix 310 is one of the least expensive detachable 2-in-1s you can buy, but it doesn’t skimp on battery life. This 2.4-pound hybrid lasts a strong 12 hours and 24 minutes on a charge while delivering a colorful screen and relatively snappy performance, given its low-power, Intel Atom processor.

Dell Latitude 5280 (12:21)

Made for serious productivity, the 12-inch Latitude 5280 features a snappy keyboard, durable chassis and plenty of ports, including an old-fashioned VGA connector and a modern USB Type-C port. Best of all, with its extended battery, the Latitude 5280 lasts over 12 hours on a charge.

Lenovo ThinkPad X1 Carbon (12:21)

The 2017 (aka 5th Generation) model of the ThinkPad X1 Carbon is the longest-lasting unit yet, enduring for a full 12 hours and 21 minutes on the Laptop Mag Battery Test. Even better, the X1 Carbon slimmed down to a feather-light, 2.49 pounds while adding an Intel 7th Gen Core Series processor, a soft-touch chassis and a Thunderbolt 3 port for charging and data.

Dell XPS 13 (11:54)

Not only did Dell manage to fit a 13-inch display into an 11-inch, 2.6-pound chassis, but it also squeezed in enough juice to last nearly 12 hours. (The touch version, which has a quad HD display, made it 7.5 hours). Add to that a Core i5 processor, 128GB SSD and 8GB of RAM, a backlit keyboard and a smooth touchpad, and you’ve got one of the best ultraportables around.

Dell Latitude 5480 (11:37)

Dell’s 14-inch business laptop lasts over 11 and a half hours on a charge, while offering a comfortable typing experience and a durable design. The optional 1080p screen is colorful, but we wish it were a little brighter.

Dell Inspiron 15 7000 Gaming (11:23)

The Inspiron 15 7000 lasts 11 hours and 23 minutes on a charge, much longer than any other gaming rig we’ve ever tested. Starting at $799, this affordable 15-inch laptop features a speedy quad core processor with an Nvidia 1050 or 1050 Ti graphics card that’s good enough to play high-end games at medium settings. The black and red chassis has a unique and compelling look.

Acer Chromebook R 13 (11:00)

This Chromebook 2-in-1 features a sharp, 1080p display and a premium aluminum design. The bendback chassis and touch screen make it ideal for running Android apps on top of Google’s browser-centric OS. You’ll also have 11 hours to enjoy the Acer R 13 between charges.

Lenovo Yoga 910 (10:36)

This attractive, 13.9-inch 2-in-1 has a nearly bezel-free screen in its brushed metal, 3-pound chassis. Lenovo’s sleek watchband hinge keeps the Yoga 910’s lid stable as you bend it back into laptop, tent, stand or tablet modes.

A vibrant display panel, which reproduces 101 percent of the sRGB color gamut, a speedy SSD and a powerful 7th Gen Core Series CPU  round out this attractive package. Better still, with over 10 hours and 36 minutes of endurance, the Yoga 910 also lasts long enough on a charge to take you through a full day of work or school.

Apple MacBook Pro 15-inch (10:32)

Apple’s high-end laptop packs a speedy, quad-core processor, discrete AMD Radeon graphics and a sharp, 2800×1800 display. Even better, while you’re enjoying all that power and functionality, you can stay unplugged for 10 hours and 32 minutes.

Asus Zenbook UX330UA (10:17)

Asus’s 13-inch ZenBook UX330UA offers great battery life and an even better value. For $699, this lightweight laptop features an aluminum lid, a 1080p screen, a 7th Gen Core i5 CPU and a 256GB SSD. With the UX330UA’s 10 hours and 17 minutes of endurance, you can leave the power plug at home.

HP Spectre x360, 13-inch (10:06)

One of our favorite consumer 2-in-1s is also one of the longest lasting. The 13-inch Spectre x360 lasts a full 10 hours and 6 minutes on a charge while providing a speedy PCIe SSD, premium aluminum design and snappy keyboard. A vibrant display shows 102 percent of the sRGB color gamut while a combination of USB Type-C and Type-A ports provides a lot of flexibility.
