Only the laptops with best battery life can crush the most premium machines no matter how stacked their specs are, because laptops are useless if they can't hold a charge.
Fortunately, there are plenty of notebooks that go the distance. Using our Laptop Mag Battery Test 2.0, which involves continuous Web surfing over Wi-Fi at 150 nits of brightness, we've identified the laptops with best battery life on the market.

We're talking more than 10 hours of endurance, which should more than suffice for that cross-country flight, a long day of meetings or multiple, back-to-back classes. These laptops can be anything, from premium consumer laptops to business laptops to even gaming laptops, yes, gaming laptops, like the Asus ROG Zephyrus G14, which achieved more battery life than the 16-inch MacBook Pro thanks to its AMD Ryzen CPU. With AMD pushing battery life as one of its key features, Intel has a ton of work cut out for it. We recently reviewed the Lenovo ThinkPad X1 Carbon (8th Gen), which nailed 10:45 and the Dell Latitude 7410, which achieved 10:56. The Lenovo Flex 5G hit a ridiculous 17 hours and 28 minutes, but it's not exactly a good laptop, so it doesn't make this list.

Note that, in February 2018, we switched from Laptop Battery Test 1.0, which surfed the web at a lower, 100 nits of brightness, so scores have gone down to reflect the more aggressive (and realistic) test.
What are the laptops with best battery life?
It’s all a numbers game, so deciding which are the laptops with best battery life is objective. Right now, the laptop with best battery life you can buy is the Dell Latitude 9510, which comes in at a ridiculous 18 hours and 17 minutes. This is one of the best business laptops that you can buy. Along with its epic endurance, this ultraportable enterprise machine has a slim yet durable chassis, a solid 1080p display and plenty of security features, including a fingerprint sensor and IR camera.
If you’re looking for a portable 2-in-1 laptop, the HP Spectre x360 is perfect for you. It lasted 13 hours and 20 minutes. Updated with Intel's 10th Gen processors and a modernized chassis, the Spectre x360 takes everything we loved about its predecessor and ramps it up. It starts with the laptop's design, which is more stunning than ever thanks to thinner display bezels and smaller footprint. Other highlights include a bright, vivid display, a comfortable keyboard, fast performance and an included stylus.
However, if you’re looking for a MacBook that matches up with the laptops with best battery life, then you’ll have to spring for the 16-inch MacBook Pro, which lasted exactly 11 hours on our test. The new 16-inch MacBook Pro is a beast, packing a totally new keyboard, a bigger display with thinner bezels, and gobs of power with up to an 8-core Core i9 CPU, 8GB of VRAM and 8TB of storage. On top of that, the audio from the 16-inch MacBook Pro is even more impressive than the visuals.

It's not easy to stand out in the crowded business laptop category. Competitors like the Lenovo ThinkPad X1 Carbon and HP's Elite Dragonfly have raised the bar, making it difficult for others to make their case. But Dell is proving that it's up to the task with the Latitude 9410 2-in-1, a sleek and sturdy business notebook with unmatched battery life.
It might not attract as much attention as those aforementioned models, but the Latitude 9410's all-aluminum chassis is thin and durable. Housed within are powerful components, including a 10th Gen Intel Core CPU capable of running demanding workloads. And when you're off the clock, the Latitude 14-inch, 1080p display captures rich colors, although it could get brighter.
But what makes the Latitude 9410 2-in-1 a true contender to the other best business laptops is its nearly 17 hours of battery life, which distracts from some minor pitfalls, like a high price and comparatively hefty weight.

The Asus ExpertBook B9450 wowed us with its battery life score. If you need a laptop with one of the best battery life scores of all time, the ExpertBook will keep you comfortable for an insane 16 hours and 42 minutes. You can literally get through two workdays without having to charge this beast.
On top of that, you get an incredibly lightweight yet durable design covered in an attractive midnight-blue shade. You'll also get some useful security features like an IR camera and fingerprint sensor. Its 14-inch, 1080p display is fairly bright and colorful as well, but its biggest asset is an anti-glare coating. Asus also equipped the ExpertBook B9450 with a speedy SSD -- Its 1TB M.2 PCIe NVMe SSD duplicated 4.97GB in 6 seconds at a rate of 771.1 megabytes per second.

The Samsung Galaxy Book Flex 15 is a blue-hued, 2-in-1 head-turning laptop that will rock your world with a built-in, show-stealing S Pen that attracts all the attention.
Taking notes (pun unintended) from its successful Galaxy Note smartphone series, Samsung packed a pizazz-filled, entertaining layer of stylus fun for artistic creatives, scribble-happy students and note-taking professionals. But the pen is just the “cherry on top” of this spectacular convertible — there’s so much more that this badass ultraportable offers.
Put your shades on! The Samsung Galaxy Book 15 (along with the Galaxy Book Ion) is the first laptop in the world to feature a QLED display, an energy-saving technology that helps to output super-high brightness scores without depleting too much battery power. Speaking of its battery, it lasted a whopping 15 hours and 44 minutes on our test.

The Gram 14 2-in-1 we reviewed last year was no fluke. After a shaky entry to the laptop market, LG has proven that it can craft a laptop as good as any. The newest Gram 14 2-in-1 is the company's best yet, boasting epic battery life and a lightweight design with military-grade durability — a big change from the flimsy paperweights LG sold just a few years back.
LG used to tout ridiculous battery life figures for earlier models. The outdated benchmarks the company used were so misleading that our real-world battery test often showed less than half the advertised endurance. So forgive us for rolling our eyes at the Gram 14 2-in-1's claimed 20.5 hours of battery life. No, the Gram 14 doesn't last for 20 hours — but it comes much closer than I expected. On our Laptop Mag battery test, the Gram 14 2-in-1 lasted for 14 hours flat.

The Dell Latitude 7400 straight up destroyed the battery test with a wild 13 hours and 23 minutes. On top of its awesome battery life, the Latitude 7400 offers speedy performance thanks to its Core i7-8665U processor. With a score of 15,865 on the Geekbench 4.1 overall performance test, the Latitude 7400 outpunched the HP EliteBook 840 G5 (14,178, Core i7-8650U) and the category average (15,724)
It also comes with a three-year warranty as the standard option. Protecting the sensitive data stored inside the Latitude 7400 are a range of security features. Those include an optional IR camera and fingerprint sensor for Windows Hello login as well as an optional smart card reader. TPM 2.0, a chip that protects unencrypted data, is one of just a few default security features. The Dell Latitude 7400 impressively lunged itself toward the top of our laptops with best battery life page.

The latest HP Spectre x360 is practically perfect, even with its battery life, which nailed a wild 13 hours and 20 minutes on our test. It's super light, at 2.7 pounds, and thin, at 0.7 inches thick, that we can't help but love the footprint on top of the elegant aluminum design.
Packed within that thin design is a strong Intel Core i7-1065G7 CPU and Intel Iris Plus graphics. With a score of 18,408 on the Geekbench 4.1 overall performance benchmark, the Specter x360 trounced its predecessor (14,935, Core i7-8565U), the Lenovo Yoga C930 (14,739, Core i7-8550U) and the category average (14,488). It also has a great keyboard, thanks to its large keys and hefty click. Making it on the laptops with best battery life page is merely a secondary award to everything else that's great about this laptop.

Let me introduce you to one of the best Dell Latitudes around: The Latitude 7400 2-in-1 -- a beast of a business laptop that can last 13 hours and 8 minutes on a single charge. That battery is packed into a super sleek design, measuring just 0.6 inches thick, alongside a strong Core i7 processor.
The notebook notched a 17,087 on the Geekbench 4.3 overall performance test, beating the HP EliteBook x360 1040 G5 (14,331, Intel Core i7-8650U), the Lenovo ThinkPad X1 Yoga (14,517, Core i7-8650U) and the category average (13,089). Debuting on the Latitude 7400 2-in-1 is a neat security feature called Dell ExpressSign-in. Baked right into the Windows 10 Power & Sleep settings, ExpressSign-in will awaken or put to sleep the Latitude 7400 2-in-1, depending on your proximity to the system.

At first glance, The Lenovo Chromebook Duet (reviewed at $279) looks like an innocuous journal, but open that bad boy up, and it’s a small laptop with a colorful 10.1-inch display.
But this device’s transformative capability isn’t its only alluring feature — the Lenovo Chromebook Duet lasted almost 13 hours on our battery test, which beats the 10-hour average runtime for Chromebooks. The price is another big selling point of the Lenovo Chromebook Duet. For under $300, you can own a lightweight machine that can endure all your intensive web multitasking.
The Lenovo Chromebook Duet sports a 10.1-inch, 1920 x 1200 display that’s impressively colorful. However, the tablet’s screen has chunky bezels that might turn you off if you’re seeking a more modern look. But the Duet is a budget-friendly Chromebook, so we can concede the lack of slim bezels as a reasonable trade off.

The Dell XPS 13 still has the slimmest bezels imaginable thanks to its InfinityEdge design, and as a bonus, Dell managed to fit the webcam in the top bezel, which has been a long-awaited feature. Oh, and its one of the laptops with best battery life. And to accompany those thin bezels is a gorgeous 13.3-inch, 1080p display that covered 126 percent of the sRGB spectrum and emitted 357 nits of brightness.
This baby is also super light and thin, coming in at 2.7 pounds and 0.3~0.46 inches thick, and boasts a powerful new Whiskey Lake processor. The laptop held its own during our synthetic testing, scoring 14,936 on Geekbench 4, which measures overall performance. That was enough to top the 12,407 premium laptop average as well as the 12,676 posted by the Surface Laptop 2 (Intel Core i5-8250U).
See our full Dell XPS 13 (2019) review.
The Lenovo Yoga C630 sports a gorgeous aluminum chassis paired with a flexible, 0.5-inch thin design. Its battery life lasted 12 hours and 14 minutes on our tests, and when you combine that with its 4G LTE connectivity, it’s great option for people who frequently travel. The Snapdragon X20 LTE modem enables the Yoga C630 to connect to the internet without a Wi-Fi connection. Switching from Wi-Fi to LTE is a breeze: Just select the Cellular button in the Windows Action Center.
As an added bonus, the Yoga C630 also features a decently colorful 13.3-inch panel. In the trailer for the upcoming Hellboy film, the half-demon's body was a rich, blood-red color, and a brief scene of a burning city singed my eyes with a vivid orange glow. The 1080p panel was so crisp that I could see every scar on Hellboy's face and all of the marks on his powerful Right Hand of Doom.
See our full Lenovo Yoga C630 review.
Between its sleek aluminum chassis, ridiculously gorgeous 15.6-inch display and powerful performance, it’s practically a miracle that the Dell XPS 15 has long battery life. This baby lasted a solid 11 hours and 53 minutes, and while that’s not the best of the best, its other qualities easily make it one of the best overall laptops on this list.
The XPS 15 did well on Geekbench 4, where it notched 19,775, besting the 11,492 premium laptop average. The XPS 15 nailed it on the Handbrake Video Editing test, taking only 10 minutes and 12 seconds to transcode a 4K video to 1080p, smoking the 21:35 average. And with its GTX 1050 Ti Max-Q GPU, you can run games like Hitman (Ultra, 1080p) at 60 frames per second.

The Lenovo Yoga C940's slim, premium chassis packs a battery that can last 11 hours and 46 minutes without issue. On top of that, you get a powerful Intel Core i7-1065G7 processor, a gorgeous 14-inch, 1080p panel and a pair of crisp speakers.
The 4K model scored an 18,709 on the Geekbench 4.3 overall-performance test, while the 1080p version was just behind, at 18,672. Those numbers top the scores from the Spectre x360 13 (18,408; Core i7-1065G7) and last year's Yoga C930 (14,739; Core i7-8550U) as well as the premium laptop average (16,314). As the Yoga moniker suggests, it is a 2-in-1 laptop and it also comes with an included stylus. The keyboard even offers a decent amount of travel considering how thin the laptop is as well as a generous amount of spacing.

I didn't think I'd see the day when a gaming laptop delivered longer battery life than a traditional notebook. But today is that day, thanks to the Asus ROG Zephyrus G14. There's almost nothing that this baby can't do. You get the new powerful AMD Ryzen 9-4900HS processor comboed with an Nvidia GeForce RTX 2060 Max-Q GPU.
It ripped and tore through Doom Eternal at 90 frames per second (fps) at 1080p on Ultra settings as I hopscotched with my shotgun up in demons' faces. On the Geekbench 4.3 overall performance test, Zephyrus G14's AMD CPU proved to be more than capable, scoring 30,181, which obliterates the 20,995 mainstream gaming laptop average. Top that off with a lightning-fast SSD, a bright, 14-inch, 120Hz display, a comfortable keyboard and strong speakers packed into a gorgeous milky-white magnesium alloy chassis, and the ROG Zephyrus G14 is a near-perfect gaming laptop.
See our full Asus ROG Zephyrus G14 review.
At just 2.3 pounds and 0.5 inches thin, the Google Pixelbook Go packs a battery that pushes it for a whole 11 hours and 29 minutes. It's rare to get a Chromebook that lasts this long on a charge. Thanks to its strong processor, the Pixelbook Go scored 6,516 on the Geekbench 4.1 overall-performance test, surpassing the 6,209 Chromebook average.
It also has a bright and colorful 1920 x 1080 display, nailing 108% of the sRGB color gamut and 368 nits of brightness. In the trailer for the film 1917, George MacKay jumped off of a balcony, and the sky behind him glowed a dark blue while warm orange fires burned in the distance; it looked bold despite some glare. In the same scene, it was dark on the bottom half of the shot, but I was still able to spot the individual bricks in the wall behind MacKay. The is the best long lasting Chromebook you can buy.
See our full Google Pixelbook Go review.
The HP Envy 13 banged out a solid 11 hours and 11 minutes on our Laptop Mag Battery Test with its bright, 1080p display. (The 1080p panel reproduces 109% of the sRGB color gamut, making it more vivid than the 4K display, which reached only 99.4%.) It also has an elegant 0.6-inch chassis that can lift the deck when the lid is open, to make for a more comfortable typing experience.
The generous size and spacing of the island-style keyboard on the Envy 13 made typing a joy. The Core i5 and Core i7 versions of the Envy 13 did an excellent job on our synthetic benchmark tests, scoring a 15,147 and 15,738 on the Geekbench 4 evaluation, respectively, surpassing the category average (15,085). Now combo that with a pair of powerful speakers. You got yourself an awesome ultraportable laptop.
See our full HP Envy 13 review.
The Acer Swift 3 also offers a vivacious 11-hour runtime of battery life. Another plus? The AMD-equipped power demon is designed for portability, so if you’re an on-the-go busy bee seeking a Herculean laptop that won’t break your back, look no further. With its Ryzen 7 4700U CPU, not only did the Acer Swift 3 smoke its Intel counterpart on performance (check out our Acer Swift 3 Intel review), but the AMD-packed ultrabook overshadowed high-performing premium laptops, too.
The Swift 3 is far from ornate, strutting around in a functional silver chassis. The Acer ultrabook doesn’t care to impress, but its minimalist exterior, which consists of magnesium and aluminum, is refined and polished. When it comes to the keyboard deck, the AMD Swift 3 model is more attractive than its Intel twin, which has basic black keys. On the other hand, the Ryzen 7 variant sports silver keys with a white keyboard backlight, which gives the keyboard an attractive frosty vibe.
See our full Acer Swift 3 (2020, AMD Ryzen 7 4700U) review.
Apple has finally made a better keyboard for its MacBooks, tossing the Butterfly switches and putting in scissor switches, which makes the 16-inch MacBook Pro. Not only that, but it lasted a straight 11 hours on the battery test.
Apple also maintained the same size as its predecessor, at 0.6-inches thin, while expanding the display size to 16 inches. Top that off with the MacBook Pro's powerful Core i9 CPU and a strong AMD Radeon 5500M graphics card. The 16-inch MacBook Pro should make quick work of video editing projects. It took the laptop only 8 minutes to transcode a 6.5GB 4K video to 1080p, which is the same amount of time the Dell XPS 15 took. On the Rise of the Tomb Raider benchmark. the 16-inch MacBook Pro turned in a decent frame rate of 27.2 fps with the resolution set to 1920 x 1200 at the very high graphics preset.

How we test the laptops with best battery life
We put each laptop through extensive benchmark testing — both synthetic and real-world — before they end up in the hands of our reviewers. We evaluate each aspect of the laptop, including its performance, battery life, display, speakers and heat management.
In our benchmark testing, we use a Klein K10 colorimeter to detect the brightness and sRGB color gamut of the laptop's display. For performance testing, we run the laptop through a gauntlet of benchmarks, including Geekbench 4.3 and 5.0 and 3DMark professional graphics tests.
To determine real-world performance, we task the laptop to convert a 4K video to 1080p resolution and to duplicate a 4.97GB multimedia file. Our real-world graphics test is the Dirt 3 benchmark with medium settings at 1080p resolution.
We also run heat tests by playing a 15-minute full-screen video and measuring temperatures in different areas of the laptop. Last but not least, our battery test consists of continuous web surfing over Wi-Fi at 150 nits of brightness. For MacBooks and premium Windows 10 laptops, a runtime of over 9 hours is considered a good result whereas gaming laptops and workstations that can stay powered for longer than 5 hours deserve praise.
These tests are complemented with extensive hands-on testing from our reviewers who critique everything from the laptop's materials to the feel of its touchpad.
