The 35 best battery life laptops for 2019

Our newly expanded rankings of longest-lasting laptops has a few surprises.

It should come as no surprise that battery life is one of the key things we look for in a laptop. What is surprising is which laptop brands and models take the top spots. They're not always the usual suspects. 

Why are we so obsessed with battery life? 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 while taking notes in a long lecture class

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 35 (up from our original 25) can be found below the five leaders.

Top Performers

LG Gram 15 13 hours, 58 minutes See at Amazon
Asus NovaGo 13 hours, 12 minutes See at Amazon
Lenovo ThinkPad X1 Carbon 13 hours, 7 minutes See at Amazon
LG Gram 14 2-in-1 12 hours, 35 minutes See at Best Buy
Samsung Notebook 9 Pro 12 hours, 30 minutes See at Best Buy

While at one time Apple's MacBooks controlled much of the top of this chart, the current winner comes from an unexpected place. LG's Gram series is best known for being very light, and the 15-inch LG Gram 15 is no exception at 2.5 pounds (even slim 15-inch laptops are usually over 4 pounds). But besides that, it ran for almost 14 hours, which is exceptionally good.  Part of the secret is that a larger 15-inch body just has room for a larger battery. Apple, on the other hand, just squeaks into the top 10 with the 15-inch MacBook Pro -- again, helped by a 15-inch body that can hold a larger battery.

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.

LG Gram 15

13 hours, 58 minutes

Sarah Tew/CNET

If lightweight, all-day battery life and a large screen size are your top must-haves for your next laptop, the LG Gram 15 is worth the expense.

Asus NovaGo

13 hours, 12 minutes

Sarah Tew/CNET

The Asus NovaGo makes good use of its Qualcomm Snapdragon 835 brain for long battery life and always-on cellular, but the performance feels more like a phone than laptop.

Lenovo ThinkPad X1 Carbon

13 hours, 7 minutes

James Martin/CNET

Besides adding HDR support and Alexa integration, last year's X1 Carbon update also scored for major battery life. 

LG Gram 14 2-in-1

12 hours, 35 minutes

Sarah Tew/CNET

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).

Samsung Notebook 9 Pro

12 hours, 30 minutes

Sarah Tew/CNET

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.
