Here, the Dell Latitude 7400 2-in-1 did very well, coming in just below the 2019 Dell XPS 13 and performing significantly ahead of than the Lenovo Yoga C930 and 2018 Dell XPS 13.

Here the Dell Latitude managed to sneak into the top 1/3 of our tested systems, beating out HP EliteBook 830/840 G5 and the Lenovo Yoga C390, but coming in just behind the 8th gen Acer Swift 3 and the 6th gen Lenovo ThinkPad X1 Carbon.

Latitude 7400 2-In-1 Battery Life And How We Test

Our custom HotHardware video loop test takes a 1080p HD video with a 16Kbps bit rate and loops it repeatedly, with 1-minute break intervals in between. A timer log file increments minutes of up-time every minute— along with the grand total—before system shutdown is stored in the log. This is a lighter-duty test that is still a bit more strenuous than many office productivity tasks, with only brief breaks in between loops; that process continues until the machine finally gives up, as its battery gasps its last.

In this test, it wasn't even a contest. With the optional 6-cell 78 Whr battery (adding $21 to the base cost), the Latitude 7400 2-in-1 ran for an impressive 688 minutes (11.46 hours) before it ground to a halt. The next closest test machine was the late 2017 Dell XPS 13, which ran for 623 minutes. The Lenovo Thinkpad X1 Yoga, with which the Latitude 7400 is meant to compete, managed 534 minutes, or just over 2 hours less total up-time.
