Dell XPS 14 Hits 43 Hours in Light Browsing on 1Hz Display

A 1Hz variable‑refresh LCD cuts screen power in static tasks, making test methods the biggest driver of the eye‑popping result.

Overview

  • Following Thursday's Hardware Canucks review, the XPS 14 logged 43 hours and 3 minutes in a light Chrome browsing run at 150 nits using an LG LCD that can drop to a 1 Hz refresh rate.
  • The screen’s 1–120 Hz variable refresh rate saves power by updating only once per second on still pages, and Intel’s Panther Lake Core Ultra 7 355 adds its own efficiency gains.
  • Tom’s Hardware, using a tougher mixed test at 150 nits, measured 20 hours and 41 minutes, and NotebookCheck saw 16 hours and 45 minutes with VRR off and the screen fixed at 120 Hz.
  • In other Hardware Canucks trials, the Dell lasted 20 hours and 21 minutes in continuous 4K YouTube playback, but only 2 hours and 38 minutes in gaming, where the M5 MacBook Air reached 4 hours and 10 minutes.
  • Reviewers note trade‑offs as the long‑lasting LCD model runs at 1920×1200 with narrower color than the OLED option, and LG says a laptop OLED panel with 1 Hz capability is planned for 2027.
