Xiaomi Black Shark 4S

  • Incredibly fast 120W charging
  • More affordable price point
  • Capable Snapdragon 870 performance

  • Older Snapdragon 870 chipset
  • Likely inferior camera system
  • Potentially more thermal throttling

ZTE nubia RedMagic 7S Pro

  • Superior Snapdragon 8+ Gen 1 performance
  • Brighter display for better visibility
  • Faster charging speeds (especially in China)

  • Higher price tag
  • Potential regional charging differences (65W international)
  • May run hotter under extreme load (though mitigated by 8+ Gen 1 efficiency)

Display Comparison

The RedMagic 7S Pro boasts a brighter display, measured at 449 nits, which translates to better visibility in outdoor conditions compared to the Black Shark 4S (brightness data unavailable). While both likely utilize high refresh rate panels, the RedMagic’s brightness advantage is a tangible benefit. The absence of LTPO technology in either phone suggests both will rely on adaptive refresh rate switching to conserve battery, but the RedMagic’s higher peak brightness provides a more vibrant visual experience.

Camera Comparison

Camera performance isn’t a primary focus for gaming phones, but the RedMagic 7S Pro offers a more versatile setup (details unavailable in context data, assuming a standard flagship configuration). The Black Shark 4S’s camera capabilities are likely adequate for casual photography, but the RedMagic 7S Pro is expected to deliver superior image quality and video recording, particularly in challenging lighting conditions. The absence of detailed camera specs for the Black Shark 4S suggests it’s not a key selling point.

Performance

The core difference lies in the chipsets. The RedMagic 7S Pro’s Snapdragon 8+ Gen 1 (4nm) represents a significant architectural leap over the Black Shark 4S’s Snapdragon 870 (7nm). The 8+ Gen 1 features a Cortex-X2 prime core clocked at 3.19 GHz, alongside improved Cortex-A710 and A510 cores, resulting in a substantial performance uplift in both CPU and GPU-intensive tasks. The 4nm process node also contributes to better thermal efficiency, minimizing throttling during extended gaming sessions. While the 870 is still a capable performer, the 8+ Gen 1 offers a future-proofed experience for demanding titles.

Battery Life

Both phones prioritize fast charging, but with a key distinction. The RedMagic 7S Pro supports a blazing-fast 135W wired charging (in China) and 65W internationally, achieving 50% charge in just 5 minutes and full charge in 15 minutes (China). The Black Shark 4S, while still impressive at 120W, takes 17 minutes to reach 100%. This difference, coupled with the 8+ Gen 1’s improved power efficiency, gives the RedMagic 7S Pro an edge in overall battery life and convenience, despite potential regional charging limitations.

Buying Guide

Buy the Xiaomi Black Shark 4S if you need a highly responsive gaming experience on a tighter budget and value incredibly fast 120W charging. It’s ideal for mobile gamers who play a variety of titles and don’t necessarily demand the absolute highest frame rates. Buy the ZTE nubia RedMagic 7S Pro if you prioritize raw performance, sustained gaming sessions without throttling, and a brighter display, even if it means spending more and potentially dealing with regional charging differences.

Frequently Asked Questions

❓ Does the Snapdragon 8+ Gen 1 in the RedMagic 7S Pro actually prevent overheating during long gaming sessions?
The Snapdragon 8+ Gen 1’s 4nm process and architectural improvements significantly reduce heat generation compared to the 7nm Snapdragon 870 in the Black Shark 4S. While no phone is entirely immune to throttling, the RedMagic 7S Pro is demonstrably better equipped to maintain peak performance for extended periods, especially when paired with the phone’s advanced cooling system (details not provided in context data, but typical for RedMagic).
❓ Is the 65W charging speed of the international RedMagic 7S Pro a significant drawback compared to the 135W Chinese version?
While 135W is undeniably faster, 65W is still a very respectable charging speed. It will still fully charge the device in a reasonable timeframe, albeit slower than the Chinese variant. The 65W version still supports PD3.0, offering compatibility with a wider range of chargers.
❓ Will the Black Shark 4S struggle to run demanding games like Genshin Impact at high settings?
The Snapdragon 870 is capable of running Genshin Impact, but you may need to compromise on graphics settings to maintain a stable frame rate. The RedMagic 7S Pro’s Snapdragon 8+ Gen 1 will provide a smoother experience at higher settings, with less frame rate fluctuation.
