The Best Laptops for Long-Lasting Battery Life

Battery life is an area where modern laptops have made significant advancements. Manufacturers claim impressive numbers, but those figures often don’t reflect real-life usage. The true battery life of a laptop depends on the task at hand.

To provide an accurate assessment, we conduct three tests in our laptop reviews. Firstly, we play a local 1080p video on loop to evaluate the impact of the display on battery longevity. Next, we use a script to run the latest version of Chrome through a series of popular websites to test typical light productivity. Finally, we run the demanding Basemark web benchmark to determine how the laptop performs under intensive CPU stress.

By combining these tests, we obtain a comprehensive assessment of a laptop’s endurance. Based on our findings, the Dell Latitude 7400 2-in-1 emerges as the top performer in terms of battery life.
