The top 35 laptop battery life performers from CNET Labs
Based on the extensive battery testing conducted in the CNET Labs, these are the 35 PCs with the longest battery-life scores that we've seen from 2018 through today. 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.
This 2018 version of the X1 Carbon laptop has a WQHD-resolution 14-inch display (2,560 by 1,440 pixels), with 100 percent Adobe RGB color gamut, brightness up to 500 nits and support for Dolby Vision HDR for greater brightness, contrast and color palette, all while bringing in big battery life numbers. Score: 13:07, or 787 minutes.
The LG Gram 14 2-in-1 laptop is an ultralight pen-enabled convertible with extraordinary battery life for its class, plus it's really, really light (just 2.5 pounds). The Gram ran for 12 hours 35 minutes, or 755 minutes.
It's not the most exciting design out there, but the 2019 Samsung Notebook 9 Pro is a slim, lightweight two-in-one with extra-long battery life, plus strong performance for its size. The Notebook 9 Pro ran for 12 hours 30 minutes, or 750 minutes.
Excellent performance along with a stylish and functional design make the Lenovo Yoga C930 simply one of the best two-in-one laptops available, and its 12-plus hours of battery life is icing on the cake. Score: 12:25, or 745 minutes.
The XPS 13 is one of our top choices for a premium Windows ultraportable laptop. The new 2019 version fixes a handful of problems, like a poorly placed webcam, but the 2018 version still beats it out on battery life. Don't worry, the 2019 version is a bit further down on this list. Score: 12:18, or 738 minutes.
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 eighth-gen Intel processors, which may even add a few minutes.
