Xiaomi 15 Ultra is brightest phone tested at 3,287 nits

The Xiaomi 15 Ultra has achieved a record display brightness of 3,287 nits in testing, surpassing its manufacturer-suggested peak of 3,200 nits. This marks it as the brightest phone tested to date, outperforming competitors like the Galaxy S25 Ultra. Recent advancements in OLED technology have led to phones with brightness levels between 2,000 and 3,000 nits becoming more common. High brightness improves screen legibility, especially in bright conditions, making devices easier to use outdoors. The Xiaomi 15 Ultra's brightness was measured in automatic mode, indicating potential for even higher levels in specialized settings. This trend towards brighter screens is expected to continue, enhancing user experience without significantly impacting battery life.
