ZTE nubia RedMagic 7

  • Blazing-fast 120W (China) charging
  • Aggressive cooling system for sustained gaming
  • Gaming-centric features (triggers, fan)

  • Dimmer display compared to the 12S Ultra
  • Less efficient Snapdragon 8 Gen 1 chipset
  • Camera is not a primary strength

Xiaomi 12S Ultra

  • Brighter and more color-accurate display
  • More efficient Snapdragon 8+ Gen 1 chipset
  • Superior camera system for photography

  • Slower wired charging than the RedMagic 7 (China)
  • No gaming-specific features like triggers
  • Less focused on raw gaming performance

Display Comparison

The Xiaomi 12S Ultra boasts a significantly brighter display, reaching 1065 nits measured, compared to the RedMagic 7’s 527 nits. This translates to vastly improved visibility in direct sunlight. While both utilize OLED technology, the 12S Ultra’s higher peak brightness and likely superior color calibration (though not specified) provide a more vibrant and accurate viewing experience. The RedMagic 7’s display is geared towards gaming with a high refresh rate, but the brightness deficit is a notable drawback for general use. Contrast ratio is infinite (nominal) on the Xiaomi, suggesting deep blacks.

Camera Comparison

Both devices are equipped with capable camera systems, but the Xiaomi 12S Ultra is positioned as a photography powerhouse. While specific sensor details are missing, the 12S Ultra’s focus on camera quality is evident in its marketing and likely sensor size. The RedMagic 7’s camera is functional for photo and video, but it’s clearly not the primary focus. The 12S Ultra’s image processing is likely more sophisticated, offering better dynamic range and low-light performance. The absence of detailed camera specs for the RedMagic 7 suggests it won’t compete with the 12S Ultra in image quality.

Performance

The Xiaomi 12S Ultra’s Snapdragon 8+ Gen 1 chipset represents a significant upgrade over the RedMagic 7’s Snapdragon 8 Gen 1. The ‘+’ variant, built on a refined 4nm process, offers improved thermal efficiency and higher clock speeds (3.19 GHz vs 3.00 GHz on the X2 core). This means the 12S Ultra is less prone to throttling during sustained workloads, delivering more consistent performance. While both phones share the same CPU core configuration (1x Cortex-X2, 3x Cortex-A710, 4x Cortex-A510), the 12S Ultra’s higher clock speeds and improved efficiency give it an edge. The RedMagic 7 compensates with its active cooling system, but this adds bulk and noise.

Battery Life

The Xiaomi 12S Ultra edges out the RedMagic 7 in endurance with a rating of 93 hours versus 89 hours. Despite having a similar battery capacity (not specified in context data, but likely comparable), the Snapdragon 8+ Gen 1’s efficiency contributes to the longer runtime. Charging speeds differ significantly: the RedMagic 7 supports 120W wired charging (China) or 65W (International), achieving a full charge in 17 minutes (China). The 12S Ultra offers 67W wired charging, taking 41 minutes for a full charge, but also includes 50W wireless charging and 10W reverse wireless charging – features absent on the RedMagic 7.

Buying Guide

Buy the ZTE nubia RedMagic 7 if you need a phone specifically engineered for extended gaming sessions, prioritizing sustained performance and cooling over all else. You’ll benefit from the 120W charging and gaming-specific features. Buy the Xiaomi 12S Ultra if you prefer a flagship smartphone with a best-in-class camera, a brighter and more color-accurate display, and a more efficient processor for everyday tasks and photography.

Frequently Asked Questions

❓ Does the RedMagic 7’s cooling fan significantly impact battery life during gaming?
Yes, the active cooling fan on the RedMagic 7 consumes power, reducing battery life during extended gaming sessions. While it prevents throttling and maintains performance, expect a noticeable decrease in runtime compared to the Xiaomi 12S Ultra, which relies on passive cooling and a more efficient chipset.
❓ How does the Snapdragon 8+ Gen 1 in the Xiaomi 12S Ultra handle demanding games like Genshin Impact?
The Snapdragon 8+ Gen 1 in the Xiaomi 12S Ultra handles demanding games like Genshin Impact exceptionally well. Its improved thermal efficiency minimizes throttling, allowing for sustained high frame rates and a smoother gaming experience compared to the Snapdragon 8 Gen 1 in the RedMagic 7, even with the RedMagic’s active cooling.
❓ Is the 67W charging on the Xiaomi 12S Ultra slow compared to the RedMagic 7’s 120W?
While 67W is slower than the RedMagic 7’s 120W (in China), the difference in real-world charging time isn’t as dramatic as the wattage suggests. The 12S Ultra still charges quickly, reaching 100% in 41 minutes. The addition of 50W wireless charging provides added convenience.
