- Dell’s XPS 14 is proven to have over 40 hours of battery life
- This was in a web browsing test where the laptop’s LG display was able to flex its VRR muscles
- That display has the ability to automatically downshift to 1Hz with static content on screen, providing huge power savings, as demonstrated here.
Dell’s new XPS laptops have once again been in the spotlight for their impressive battery life, and this time it’s because of a truly eye-opening result.
The XPS 14 was tested by Hardware Canucks as seen on YouTube (as noted by Notebookcheck.net; see video below) and was found to have just a hint of over 43 hours of battery life.
Yes, 43 hours, you read that correctly, in a test involving web browsing (in Chrome) with the brightness set to 150 nits. And this is for a Windows 11 laptop, while great battery life tends to be the domain of Arm-based laptops. In fact, Hardware Canucks compared the

Why is there such a difference here? Well, it’s due to the type of testing (the gap between Apple and Dell devices is not that big in the video playback and gaming tests (but the XPS 14 still wins by a good margin)) and a critical piece of technology that Dell has used, namely a panel with a new implementation of VRR (variable refresh rate). Next, let’s dive into why this is important.

Analysis: VRR situational advantage with the XPS 14
As I noted before, when the
This innovation means that VRR can adjust the display’s refresh rate to a measly 1Hz automatically when there’s static content on the screen. (Note: This is the LCD version, while the OLED on the XPS 14 and 16 can go down, but only to 20Hz, although LG Display will launch a 1Hz-capable OLED panel next year.)
The reason this is important is because web pages are static content (well, mostly), so the Of course, you don’t see as big an effect with moving content (videos, games), since higher refresh rates are needed there (the LG panel is 120Hz, in case you were wondering).
Notebookcheck.net itself tested the
As always, battery life will vary, even if running the same type of test, depending on what exactly you’re doing and the configuration aspects of the laptop, as noted, but getting over 40 hours of longevity in any test is a truly amazing result, frankly, especially for a non-Arm Windows laptop.
