The top 25 laptop battery life performers from CNET Labs
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 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.
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 750 minutes, or 12 hours, 30 minutes.
