The top 25 laptop battery life performers from CNET Labs

Forget screen size, processing power or number of ports. The first thing every laptop shopper should think about in a new purchase is battery life. After all, you don't want your PC shutting down in the middle of a Netflix binge or coffee shop brainstorming session. 

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.

Dell XPS 13 (2018)

The XPS 13 is one of our top choices for a premium Windows ultraportable laptop at its size, due in part to its speedy performance and 12-hour battery life. But, we're also very excited to check out the coming-soon 2019 version, which fixes an annoying webcam issue found on previous models. Hopefully the battery life will keep up. Score: 12:18 or 738 minutes
