It should come as no surprise that battery life is one of the key things we look for in a laptop.
More than screen size, processing power or number of ports, it’s the first thing many laptop shoppers think about before making a purchase. 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 PCs with the longest battery-life scores that we’ve seen over 2018 and 2019.The top five current performers are below, and a full list of the top 25 can be found here.
Our master 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 2-in-1 with extra-long battery life, plus strong performance for its size.
