Xiaomi 15T Pro

  • Superior chipset performance with Dimensity 9400+
  • Faster 90W wired and 50W wireless charging
  • Longer battery endurance (57:43h)

  • Potentially less refined software experience
  • Design may be less distinctive than Nothing Phone (3)

Nothing Phone (3)

  • Unique and eye-catching design
  • Cleaner, more streamlined software experience
  • Slightly brighter display (1507 nits)

  • Slower chipset (Snapdragon 8s Gen 4)
  • Slower charging speeds (65W wired, 15W wireless)

Display Comparison

The Nothing Phone (3) boasts a marginally brighter display at 1507 nits compared to the Xiaomi 15T Pro’s 1419 nits, offering a slight advantage in direct sunlight visibility. However, both displays are excellent. Neither specification details refresh rate or panel technology (LTPO), so we must assume standard OLED panels. The Nothing Phone (3)'s brightness advantage is likely more noticeable in outdoor scenarios, while the 15T Pro’s display will still provide a vibrant viewing experience.

Camera Comparison

Without detailed camera specifications, a direct comparison is limited. However, the market positioning suggests the Xiaomi 15T Pro will likely feature a more versatile camera system, potentially with a larger main sensor. The Nothing Phone (3) will likely focus on computational photography and a unique aesthetic. The absence of information regarding sensor sizes and optical image stabilization (OIS) makes a definitive judgment impossible, but Xiaomi typically prioritizes high-resolution sensors.

Performance

The Xiaomi 15T Pro’s Mediatek Dimensity 9400+ (3nm) chipset is architecturally superior to the Nothing Phone (3)’s Qualcomm Snapdragon 8s Gen 4 (4nm). The Dimensity 9400+ features a Cortex-X925 prime core clocked at 3.63 GHz, alongside three Cortex-X4 cores at 3.3 GHz, and four Cortex-A720 cores at 2.4 GHz. This configuration, built on a smaller 3nm process, promises greater efficiency and performance compared to the Snapdragon 8s Gen 4’s Cortex-X4 prime core at 3.21 GHz, three Cortex-A720 cores at 3.0 GHz, two at 2.8 GHz, and two at 2.0 GHz. The 3nm process node of the Dimensity 9400+ should translate to better thermal management under sustained load, minimizing throttling during extended gaming sessions.

Battery Life

The Xiaomi 15T Pro delivers a measured battery endurance of 57:43 hours with 1600 charge cycles, while the Nothing Phone (3) achieves 56:23 hours with 1400 cycles. The 15T Pro also boasts a significantly faster active use score of 16:24 hours compared to the Nothing Phone (3)’s 12:56 hours. Crucially, the 15T Pro supports 90W wired charging, reaching 100% in just 36 minutes, and 50W wireless charging in 56 minutes. The Nothing Phone (3) offers 65W wired charging, 15W wireless, and even 7.5W reverse charging, but its charging speeds are considerably slower. The 15T Pro’s superior charging capabilities are a major advantage for users who prioritize minimizing downtime.

Buying Guide

Buy the Xiaomi 15T Pro if you need uncompromising performance for demanding tasks like gaming or video editing, and value the fastest possible charging speeds. Buy the Nothing Phone (3) if you prefer a distinctive design, a cleaner software experience, and a slightly brighter display, and are willing to trade some raw power for a more refined user interface.

Frequently Asked Questions

❓ How does the Dimensity 9400+ handle sustained gaming compared to the Snapdragon 8s Gen 4?
The Dimensity 9400+'s 3nm process and more powerful CPU core configuration should result in better thermal management and less performance throttling during extended gaming sessions. While the Snapdragon 8s Gen 4 is capable, the 15T Pro is likely to maintain higher frame rates for longer periods.
❓ Is the 50W wireless charging on the Xiaomi 15T Pro significantly faster than the 15W on the Nothing Phone (3)?
Yes, the 50W wireless charging on the 15T Pro is considerably faster. It can fully charge the device in approximately 56 minutes, while the Nothing Phone (3)'s 15W wireless charging will take significantly longer – likely over two hours.
❓ Does the Nothing Phone (3)'s reverse wireless charging offer practical utility?
The 5W reverse wireless charging on the Nothing Phone (3) is primarily useful for charging small accessories like earbuds or smartwatches. It's not powerful enough to significantly charge another phone.
❓ What type of software experience can I expect from each phone?
The Xiaomi 15T Pro will likely run MIUI, which is feature-rich but can be perceived as bloated by some users. The Nothing Phone (3) runs Nothing OS, known for its clean, minimalist interface and near-stock Android experience.
