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.

Our top five picks are presented in more depth here, or jump to the last page in this gallery to see all the top performers listed. 

Last updated May 2019. Note that CNET may get a share of revenue from the sale of products featured throughout this story.
