Club Benefits
A decade ago, I would applaud any laptop that would last over eight hours (a working day). Today, the best laptops for battery life can hit over 20 hours, and we've done the testing to prove it.
At Tom's Guide, we test and run the latest laptops through multiple instances of our battery test, which tasks the laptop with endlessly surfing the web via Wi-Fi with its screen set to 150 nits of brightness, then timing how long it takes to run out of power. You've seen those bold number claims from manufacturers, and they're rarely the case. But we're here to cut through the noise to show you the stamina champions.
Keep in mind that battery life fluctuates based on several factors, including what you're doing and how your laptop is configured. So while I stand by the numbers in this list, your own battery life with these laptops may vary!

The longest-lasting laptop
Previously, the 16-inch MacBook Pro with M4 Pro took the crown as the laptop with the longest battery life, lasting 20 hours and 46 minutes. Well, the MacBook Pro M5 Pro has taken over the top spot, officially being the longest-lasting laptop we've tested.
Apple claimed the M5 Pro model can last up to 24 hours. As it turns out, it's only just over a couple of hours off the mark now, as in our battery tests, the 16-inch MacBook Pro boasted 21 hours and 10 minutes of stamina. That's a stunning results! And it means you can let this machine run throughout your workday and beyond without even thinking about grabbing a charger.
The M5 Pro chip isn't just about power efficiency, though, as it also brings powerful performance to breeze through heavy video editing, 3D rendering and more. Plus, with its Wi-Fi 7 support, 1TB base storage and always-gorgeous 16.2-inch (3,456 x 2,234) Liquid Retina XDR display with a 120Hz refresh rate, this laptop is made for power users on the move.
Sure, the last model still has amazing battery life, and it's a shame the M5 Pro laptop is now $200 more. But for those after the best battery life in a laptop right now, the MacBook Pro delivers.

The best budget laptop for battery life
While it isn't a perfect laptop, the Lenovo IdeaPad Slim 3x offers fantastic battery life, with its 16 hours and 23 minutes it boasts, and solid performance at a price that's tough to beat. If you can find it on sale, it's a serious bargain. This laptop would be an especially good pick for students and casual users, but it probably isn't the right choice for power users and gamers.
If you're looking for a sub-$1,000 laptop that will easily last all day on a single charge, the IdeaPad Slim 3x could be perfect for you. Its battery life is impressive enough that it outweighs less significant drawbacks like a lackluster display and quiet speakers. It's hard to find battery life this long at such a low price, so that alone makes the IdeaPad Slim 3x stand out.
While its drawbacks might be deal-breakers for some, if battery life and price are your top concerns, the IdeaPad Slim 3x could be the perfect choice.

The best Windows laptops for battery life
Finally, Dell decided to bring back its XPS lineup, with its XPS 13 (2024) and its Snapdragon X Elite chip delivering one of the longest-lasting laptops to date at close to 20 hours. But the Dell XPS 14 (2026) has outdone its predecessor with a whole new chip.
Now, if you head into our XPS 14 review, you may be wondering how this premium notebook could make it on this list with its still-adequite 12 hour and 23-minute battery life. Well, that's for the OLED model, but for the lower-end configuration with a 1200p LED display, it lasts an astonishing 20 hours and 41 minutes.
That raises the bar on Windows machines, and it has Intel Panther Lake to thank for that. This model's Intel Core Ultra 5 325 CPU and LED panel may not deliver as strong performance or visuals as its higher-end sibling, but you're still getting Wi-Fi 7 connectivity, good performance for everyday tasks and a slim, practical design with plenty of Thunderbolt 4 ports.
Dell is back with one of the longest-lasting laptops you can get, so if you're all about Windows and prefer a machine that has stamina, this one's for you.

The best value for battery life
The MacBook Air ticks all the right boxes, which is why we recommend it as the go-to laptop for most people. And one of the big reasons is because of its brilliantly long battery life. With the M5 model, it now pushes its limits further.
With an average runtime of 15 hours and 30 minutes (that's for both the 13- and 15-inch models, with the 13-inch clocking just two minutes behind), this is the kind of battery life where it's not a massive problem if you forgot to pack your charger. Not exactly the 18 hours Apple claims, but depending on how you use it, this laptop will last for ages.
Unfortunately, the MacBook Air M5 is $100 more than its M4 predecessor, but you're getting 512GB base storage and Wi-Fi 7 connectivity this time around. Plus, that M5 chip offers up blazing-fast performance for juggling multiple tabs and apps, and has enough power to play Resident Evil 4 Remake at a rock-solid 60 FPS. Impressive!
For its price (especially when inevitable discounts arrive, so keep an eye out), the MacBook Air M5 shines — and brighter than ever with its slightly longer battery life over its M4-equipped sibling.

The best creator laptop for battery life
It couldn't last quite as long in our battery tests as its 16-inch sibling, but the new 14-inch MacBook Pro M5 is still an all-star performer that lasted 18 hours in our testing lab. It looks good doing it too, thanks to the 14-inch mini-LED Liquid Retina XDR display, and in our lab tests, we saw that its display is even brighter than its predecessor.
This latest model sports three Thunderbolt 4 ports. And as before, this laptop has MagSafe charging, an SD card slot, an HDMI port, and a headphone jack.
During the Tom's Guide battery test, the MacBook Pro M4 lasted an epic 18 hours while continually surfing the web at 150 nits of screen brightness. Its keyboard remains unchanged, and its power button continues to integrate a Touch ID button for easy logins.

The best OLED laptop for battery life
Who says OLED laptops can't last? Well, many, and rightfully so: OLED-equipped machines take up a lot of power to deliver those rich colors, deep blacks and brilliant brightness. For the Samsung Galaxy Book 6 Pro, however, it goes against the grain to deliver astonishing stamina.
With 15 hours and 17 minutes under its belt, this laptop will last you nearly two full working days before running out of juice. It goes to show the amazing power efficiency it boasts, in no small part due to the Intel Core Ultra X7 358H (Panther Lake) CPU it offers.
Despite coming equipped with a gorgeous 16-inch (2880 x 1800) AMOLED 2X touch display with an adaptive refresh rate going up to 120Hz, this elegantly thin, lightweight laptop is able to last ages, but it still delivers plenty of power to conquer workloads. It even goes two-to-two with the M5 chip when it comes to heavy-duty multitasking, and it also runs the latest games with ray tracing thanks to its integrated graphics (its battery will plummet when gaming, of course).
If you can ignore the Samsung bloatware and aren't bothered by the AI features it holds, the Samsung Galaxy Book 6 Pro is a fantastic choice if you're after a long-lasting laptop with the glory of OLED visuals.

Battery life test results
If you made it this far, you know battery life is one of the key things to look at when deciding which laptop to buy, which is why we run every laptop we review through a series of battery tests to see how long it lasts on a full charge.
These tests do not reflect real-world use patterns since we have to set every laptop to the same settings in order to do fair comparisons. Thus, while the times listed here are accurate and useful as a comparison point, your own experience with a laptop's battery life will likely vary.
This is because when we run our battery test, we set the laptop's display to 150 nits of brightness and have it endlessly browse the web via Wi-Fi until it dies. However, when you use your laptop, you're likely adjusting brightness on the fly, doing all sorts of different tasks while perhaps listening to music or watching a video at the same time, and generally putting the machine through more of a workout than it gets in our test.
So while I stand by our testing and the battery life results we compare in the chart below, I want to be clear that your own experience will vary!
Laptop | Battery life (hh:mm) |
MacBook Pro 16-inch M5 Pro | 21:10 |
Dell XPS 14 (2026) | 20:41 |
MacBook Pro 14-inch M5 | 18:00 |
Lenovo IdeaPad Slim 3x | 16:29 |

How to choose the right long-lasting laptop for you
What kind of power do you need? Forget about battery power for a minute — what kind of performance do you need from your new laptop? If you only need something basic for surfing the web, consider the Lenovo IdeaPad Slim 3x: it's not fancy, but you can get one for cheap, and they're still plenty good enough for surfing the web. But if you want to get work done, something nicer like the XPS 14 or MacBook Pro M5 might be easier on you. And if you need raw power, the MacBook Pro M5 Pro is the way to go.
What kind of games do you want to play? Most mainstream laptops (including nearly everything on this list) feature integrated graphics, which can handle lightweight titles such as Minecraft and Fortnite but aren't ideal for graphically demanding games or heavy visual work. For that, you'll want a laptop with a discrete graphics card (which typically have terrible battery life) or a MacBook Pro, which doesn't support as many games as a Windows machine but has more than enough power to run many at great framerates.
Do you want macOS or Windows? Once upon a time, Chromebooks were the industry leaders in battery life, but nowadays it's Macs and Windows machines leading the pack. So the main thing to decide if you want the best battery life is, Mac or Windows?
The Windows laptops with the best battery life are currently Snapdragon laptops, which means they're powered by Qualcomm's ARM chips and thus have some compatibility issues with select software. The top MacBooks all run on Apple silicon and have good software support for everything except games, which are more hit-and-miss on Apple's laptops.
Whichever system you decide on, you may also want to consider investing in the best mouse and best keyboard for your needs so you can have some more ergonomic options for working on your new laptop.
How we test the best laptops for battery life
To find the best laptop, we run every machine through a rigorous suite of benchmarks and real-world tests to gauge how it will perform during everyday use.
We measure the average brightness and color quality of each laptop's display using our in-house light meter and colorimeter. For general performance, we run our machines through tests that include Geekbench 6 (CPU performance), as well as various 3DMark tests to measure graphics capabilities.
We also run a file transfer test to measure how fast a machine's hard drive is, and our custom battery test that has the machine browse the internet over Wi-Fi until it runs out of juice.
