How little energy could it consume? Checking the notebook has tried a version of the laptop with that LG Display and a new Intel Panther Lake chip, and it appears to be the most efficient laptop out there ever passed through its Wi-Fi web browsing test. At idle, the Core Ultra 325 laptop consumed just 1.5 watts and lasted nearly 27 hours of web browsing despite only housing a 70 watt-hour pack. That’s well below the 99.5 Wh that Dell has sometimes included in its 16-inch models.
That’s more battery life than Checking the notebook has come out of any MacBook or MacBook Pro, and apparently more than all laptops except two more since it started running this test in 2014. And of those two laptops, one trusted on a Qualcomm Snapdragon the other had two batteries for a total of 149Wh and a 60Hz screen too.
I should warn you that we typically see much less battery life in a real work day than we do in fixed battery life tests. But compared to other laptops, this Dell + Intel + LG display combination seems to be the new battery life champion. Note that Dell also sells it with a higher resolution tandem OLED display; You’ll have to make do with 1920 x 1200 and no touchscreen for the best battery life.
While Dell may deserve a lot of credit as a systems integrator, this technology may not be exclusive to Dell for long. LG display announced which has become the first in the world to mass produce a 1-120Hz laptop LCD panel (which it calls Oxide 1Hz) and plans to mass produce an OLED version in 2027. Intel isn’t working with just one display supplier either: last October, announced that it was working with Chinese panel manufacturer BOE also on computers with 1 Hz refresh rate.
