Just how little power might it consume? Notebookcheck has tested a version of the laptop with that LG Display screen and a new Intel Panther Lake chip — and it appears to be the most efficient laptop that’s ever gone through its Wi-Fi web browsing test. At idle, the Core Ultra 325 laptop drew as little as 1.5 watts, and lasted nearly 27 hours of web browsing despite only housing a 70 watt-hour pack. That’s well shy of the 99.5Wh Dell has sometimes crammed into its 16-inch models.

That’s more battery life than Notebookcheck has gotten out of any MacBook or MacBook Pro, and apparently more than all but two other laptops since it started running this test in 2014. And of those two laptops, one relied on a Qualcomm Snapdragon X Plus chip, a larger 84Wh battery, and a mere 60Hz screen — while the other had two batteries for a total of 149Wh and a 60Hz screen as well.

I should caution you that we typically see much less battery life in an actual workday than we do in fixed battery life tests. But compared to other laptops, this Dell + Intel + LG Display combo seems like the new battery life champ. Note that Dell also sells it with a higher-res tandem OLED screen, though. To get the best battery life, you’ll need to settle for 1920 x 1200, no OLED, and no touchscreen.

While Dell may deserve a lot of credit as the system integrator, this tech may not be exclusive to Dell for long. LG Display announced that it’s become the first in the world to mass-produce a 1–120Hz laptop LCD panel (which it’s branding as Oxide 1Hz), and plans to mass-produce an OLED version in 2027. Intel, too, isn’t just working with one display vendor: last October, it announced it was working with Chinese panel maker BOE on 1Hz refresh rate computers too.
