1Hz laptop display reportedly helps deliver outstanding 43-hour battery life on the XPS 14 during web browser use — beats the M5 MacBook Air by more than 28 hours in the same test

The Dell XPS 14 boasts a 1Hz to 120Hz variable refresh rate LCD panel that significantly enhances battery life, achieving an impressive 43 hours and 3 minutes during light Chrome web browsing tests. In comparison, the M5 MacBook Air only managed 14 hours and 30 minutes in the same scenario, showcasing a substantial 28-hour difference. The XPS 14 also outperformed the MacBook Air in 4K YouTube playback but fell short in gaming endurance. The power-efficient LG display on the XPS 14 allows it to drop to a 1Hz refresh rate when not needed, contributing to its exceptional battery performance.
