Notebooks with the Longest Battery Life

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.

Having debuted in 2015, the 13-inch MacBook Air may be a bit out of date, but it’s still for sale and now an even better value at $899.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.

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.

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.

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.

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 Dell latitude d830 laptop battery , the Latitude 5280 lasts over 12 hours on a charge.

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.

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’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.

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.

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.

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’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’s 13-inch ZenBook UX330UA offers great Asus a32-f3 notebook 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.

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.
