ZTE nubia Red Magic 7

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

  • Snapdragon 8 Gen 1 is less efficient than 8+ Gen 1
  • Camera likely inferior to the 12S Ultra
  • Software may be less refined

Xiaomi 12S Ultra

  • Snapdragon 8+ Gen 1 offers better efficiency and performance
  • Exceptional camera system
  • Bright and vibrant display

  • Slower charging speeds (67W wired)
  • No wireless charging
  • Less focused on gaming-specific features

Display Comparison

Both devices feature displays with an 'Infinite' contrast ratio, suggesting deep blacks. However, the Xiaomi 12S Ultra boasts a measured peak brightness of 1065 nits, significantly exceeding what’s likely available on the Red Magic 7, making it more usable in direct sunlight. While both are likely high refresh rate panels, the Red Magic 7’s focus on gaming suggests a potentially higher PWM dimming rate, which could benefit users sensitive to flicker. The 12S Ultra’s brightness advantage is a clear win for outdoor visibility.

Camera Comparison

Both phones are listed as having Photo/Video capabilities, but the Xiaomi 12S Ultra is expected to excel in this area, given Xiaomi’s history with flagship camera systems. While specific sensor details are missing, the 12S Ultra likely features a larger main sensor and more sophisticated image processing algorithms. The Red Magic 7, geared towards gaming, likely prioritizes camera functionality less, resulting in a less competitive imaging experience. The 12S Ultra’s camera system is a major selling point, while the Red Magic 7’s is likely adequate but not exceptional.

Performance

The Xiaomi 12S Ultra’s Snapdragon 8+ Gen 1 (4nm) represents a significant architectural improvement over the Red Magic 7’s Snapdragon 8 Gen 1 (4nm). The ‘+’ variant features higher clock speeds (3.19 GHz vs 3.00 GHz on the X2 core, and 2.75 GHz vs 2.50 GHz on the A710 cores) and, crucially, a more efficient manufacturing process. This translates to better thermal management and sustained performance under load, reducing the likelihood of throttling during prolonged gaming. While both utilize LPDDR5 RAM, the 8+ Gen 1’s efficiency gains are the key differentiator.

Battery Life

Both phones achieve similar endurance ratings (89h for Red Magic 7, 93h for 12S Ultra), suggesting comparable real-world battery life despite the Red Magic 7’s faster 120W (China) / 65W (International) charging. The 12S Ultra offers 67W wired, 50W wireless, and 10W reverse wireless charging, providing greater versatility. The Red Magic 7’s 120W charging (in China) is significantly faster, reaching 100% in just 17 minutes, a boon for gamers needing quick top-ups. However, the international version’s 65W charging is slower. The 12S Ultra’s wireless charging is a feature absent on the Red Magic 7.

Buying Guide

Buy the ZTE nubia Red Magic 7 if you need a phone specifically engineered for extended gaming sessions, prioritizing sustained performance and rapid charging over all else. Buy the Xiaomi 12S Ultra if you prefer a versatile flagship with a world-class camera system, excellent display brightness, and a more refined software experience, even if it means slightly less raw gaming horsepower.

Frequently Asked Questions

❓ Does the Snapdragon 8 Gen 1 in the Red Magic 7 suffer from significant thermal throttling during extended gaming sessions?
The Snapdragon 8 Gen 1 is known to generate more heat than the 8+ Gen 1. While the Red Magic 7 incorporates an aggressive cooling system, prolonged, demanding gaming sessions may still result in some throttling, potentially impacting sustained performance. The 12S Ultra’s 8+ Gen 1 is less prone to this issue.
❓ How does the 67W charging on the Xiaomi 12S Ultra compare to the 65W charging on the international Red Magic 7 in terms of real-world charging time?
While both offer fast charging, the Xiaomi 12S Ultra’s 67W charging, combined with its optimized power management, is likely to be slightly faster in practice than the Red Magic 7’s 65W international variant. The Red Magic 7’s 120W charging (China only) is significantly faster, however.
❓ Is the 50W wireless charging on the Xiaomi 12S Ultra a practical alternative to wired charging?
50W wireless charging is relatively fast and convenient, but it will still take longer to fully charge the device compared to the 67W wired charging. It's a great option for topping up throughout the day or overnight, but for a rapid charge, wired is still preferable.
❓ What kind of gaming experience can I expect on the Xiaomi 12S Ultra compared to the Red Magic 7?
The Xiaomi 12S Ultra will deliver a very smooth gaming experience, but the Red Magic 7 is specifically optimized for gaming. The Red Magic 7’s cooling system, dedicated gaming triggers, and software optimizations provide a more immersive and sustained gaming experience, even if the 8+ Gen 1 in the 12S Ultra is more efficient.
