Dark mode started as a visual novelty, but in 2025, it's a UX standard. From mobile apps to SaaS dashboards, users increasingly expect the ability to switch between light and dark themes.
In low-light environments, bright screens can cause discomfort and fatigue. Dark mode offers a softer visual experience that's easier on the eyes, especially for users who work long hours or browse at night.
On OLED screens, dark pixels use significantly less power. Apps with dark mode can extend device battery life—a small but meaningful improvement in mobile UX.
