Xiaomi 15T
- Exceptional battery life (57:44h endurance)
- Faster 67W wired charging
- Potentially stronger multi-core performance with Dimensity 8400 Ultra
- Camera specifications are unknown
- Software experience (MIUI) may not appeal to all users
Nothing Phone (2)
- Unique and stylish design
- Clean and minimalist Nothing OS

- Slower wired charging speed
Display Comparison
The Xiaomi 15T boasts a significantly brighter display, reaching a measured peak of 1525 nits, compared to the Nothing Phone (2)'s 998 nits. This translates to superior visibility under direct sunlight. While both utilize 4nm chipsets, the display brightness difference is a key advantage for outdoor users. The 15T's panel specifications (beyond peak brightness) are not provided, but the higher nits value suggests a more vibrant and readable experience. The Nothing Phone (2)'s display, while still good, will appear comparatively dimmer in bright conditions.
Camera Comparison
The provided data for the Nothing Phone (2) simply states 'Photo / Video,' lacking specific sensor details. This suggests the camera is a key selling point, but without sensor size or aperture information, a direct comparison is difficult. The Xiaomi 15T's camera specifications are also absent. Given Nothing's marketing focus on camera quality, it's reasonable to assume a competitive sensor, but the lack of detail hinders a thorough assessment. We can infer that both phones will likely offer capable cameras, but the Nothing Phone (2) may lean towards image processing that emphasizes a specific aesthetic.
Performance
Both devices employ 4nm chipsets, but their architectures differ significantly. The Xiaomi 15T utilizes the Mediatek Dimensity 8400 Ultra, featuring a unique octa-core configuration with three Cortex-A725 cores clocked at 3.0 GHz. The Nothing Phone (2) is powered by the Qualcomm Snapdragon 8+ Gen 1, with a Cortex-X2 prime core at 3.0 GHz. While clock speeds are similar, the Snapdragon 8+ Gen 1 is known for its efficient thermal management and strong GPU performance. However, the Dimensity 8400 Ultra's core configuration may offer advantages in multi-threaded tasks. The 15T's CPU architecture suggests a focus on sustained performance, while the Snapdragon 8+ Gen 1 prioritizes peak performance and efficiency.
Battery Life
The Xiaomi 15T dominates in battery endurance, achieving a remarkable 57:44h rating and supporting 1600 charge cycles, indicating long-term battery health. This is substantially higher than the Nothing Phone (2)'s older 103h endurance rating. While the Nothing Phone (2) offers the convenience of 15W wireless charging and 5W reverse wireless charging, the Xiaomi 15T compensates with significantly faster 67W wired charging, reaching 100% in just 50 minutes, compared to the Nothing Phone (2)'s 55 minutes. The 15T's active use score of 14:56h also surpasses the Nothing Phone (2)'s 14:21h, confirming its superior battery performance.
Buying Guide
Buy the Xiaomi 15T if you need maximum battery life, fast charging, and uncompromising performance for demanding tasks like gaming or video editing. You'll benefit from the Dimensity 8400 Ultra's power and the assurance of all-day (and then some) usage. Buy the Nothing Phone (2) if you prefer a distinctive design, a clean and minimalist software experience with Nothing OS, and wireless charging convenience, even if it means slightly shorter battery life and a marginally slower charging speed.
