LG Gram 15

This shockingly light 15-inch laptop (it's about 2.5 pounds) also has amazing battery life, jumping to the top of our current list at 13 hours and 58 minutes (838 total minutes). 

HP Spectre x360 13 (late 2017)

One of our favorite laptops, this high-end 2-in-1 ran for 13 hours and 9 minutes (799 minutes total), despite being very thin and adding a new, more powerful processor in its latest version.

Asus NovaGo TP370QL

The first Qualcomm Snapdragon-powered laptop we've tested falls a bit short on performance and features, but kills it in battery life at 13 hours, 12 minutes (792 minutes). 

Acer Chromebook R13

This excellent Chromebook previously held the top spot on our list at 782 minutes, which is 13 hours and 2 minutes.

Lenovo Yoga 920

A new addition, this high-end version of Lenovo's Yoga 2-in-1 ran for 12:50, or 770 minutes.

Dell XPS 13 (Core i5) 9370

A great redesign of an already great laptop, the new XPS 13 (now available in white-and-gold) ran for an impressive 12:16 (736 minutes). 

Samsung Notebook 9

This 15-inch super-slim laptop impressed us with very long battery life at 12:16, or 736 minutes. 

Dell XPS 13 (late 2017)

Right behind the new model is the previous Dell XPS 13. It's full HD version that ran for 12:16 (a 4K version ran for less time).

Acer Aspire E15-57G6

Acer's very low-cost 15-inch includes a DVD drive (a rarity these days), an Nvidia MX150 GPU and a battery that runs for a decent 11 hours, 58 minutes (718 minutes). 

Lenovo Thinkpad X1 Carbon

The latest X1 Carbon, a professional laptop, ran for an impressive 11:50, or 710 minutes, making this the highest-scoring business laptop on the list.

Microsoft Surface Book

The previous version of this Microsoft hybrid, which has an extra battery in its keyboard base, ran for 709 minutes, or 11:49. The newer Surface Book 2 ran for even longer in initial testing, but we found it to have inconsistent battery life scores over time, so we're not including it here.

Apple MacBook Pro (13-inch)

The best MacBook is now the 13-inch Pro, without the OLED Touch Bar, at 696 minutes, or 11:36. The 15-inch Pro was only slightly behind. 

HP EliteBook x360

HP's x360 version of the EliteBook, another business laptop, ran for 694 minutes, even with a powerful Core i7 processor. A newer version, the EliteBook x360 1020 G2, with a built-in privacy screen, was not as impressive, and failed to make the top 25. 

Asus Zenbook UX331U

This great super-slim laptop combines some basic Nvidia graphics with 10 hours, 45 minutes (645 minutes) of battery life. 

LG Gram 13

LG's lightweight Gram 13 ran for 690 minutes, which used to be a Top 5 score, but no longer. 

Apple MacBook Pro 15-inch, 2017

The current generation of MacBooks haven't changed much, but the 15-inch model has a huge battery, which helped it run for 10:43 (643 minutes). 

Asus Zenbook US461U

Another slim Asus laptop, this time with a hybrid hinge and battery life of 10 hours, 29 minutes (629 minutes).

Apple MacBook (12-inch, 2017)

The third-gen 12-inch MacBook was just a few minutes behind, coming in at 626 minutes, or 10:26. It has a lower-power processor than other MacBooks, but also a much smaller battery. 

Lenovo Flex 5

Lenovo's Flex line is one of our favorite value brands. This is an excellent budget hybrid with impressive battery life at 10 hours and 23 minutes. 

Dell Latitude 7390 2-in-1

This basic hybrid from Dell has especially good speakers for movie-watching, and a pretty decent 10 hours, 22 minutes (622 minutes) of battery life. Newer models have 8th-gen Intel processors, which may even add a few minutes. 

Microsoft Surface Laptop

Microsoft's Surface Laptop also has excellent battery life, despite a thin design and high-res screen. It ran for 621 minutes, or 10:21. 

Apple MacBook Air (2017)

The ever-so-slightly updated MacBook Air is still a battery champ at 10 hours and 10 minutes. 

Toshiba Portege X20W-D

This slim, biz-ready Toshiba, the first laptop from that brand we've reviewed in a few years, ran for 610 minutes, or 10:10. 

Apple MacBook Pro with Touch Bar (15-inch)

The MacBook Pro (last redesigned in late 2016) uses a big custom battery to run for 608 minutes, or 10:08. A CPU update several months later added about half an hour to land further up on this list. 

Apple MacBook Pro with Touch Bar (13-inch)

Adding a Touch Bar and a more powerful processor to the 13-inch MacBook Pro gets you battery life of 607 minutes. Basically, every current MacBook, and even a couple of previous versions, made this list. Apple is no longer the top dog in laptop battery life, but it's still in the game.
