Top laptop battery life performers
The most important feature for many laptop shoppers is battery life, and rightly so.
Based on the extensive battery testing conducted in the CNET Labs, these are the 25 PCs with the longest battery-life scores that we’ve seen over 2017-2018. This list includes Windows and MacOS laptops, Windows two-in-one hybrids, and Chromebooks running Google’s Chrome OS. Not included are Android or iOS tablets.
The specific test used here streams a private video over Wi-Fi on an endless loop. Note that these scores reflect the specific configurations we tested, and that screen resolution and CPU choice are some of the major factors that affect battery life.

One of our favorite new 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.
This excellent Chromebook previously held the top spot on our list at 782 minutes, which is 13 hours and 2 minutes.
A new addition, this high-end version of Lenovo’s Yoga 2-in-1 ran for 12:50, or 770 minutes.
This 15-inch super-slim laptop impressed us with very long battery life at 12:16.
The popular XPS 13 from Dell ran for 12:16, in a version with a standard FHD screen (a 4K version ran for less time). A redesign of this system was recently announced, and we look forward to testing it.
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.
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.
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’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.
