ZTE nubia Red Magic 6

  • Exceptional battery endurance (88h rating)
  • Balanced performance with Snapdragon 888
  • Potentially better sustained performance due to thermal design

  • Slower charging speed compared to the Black Shark 4S Pro
  • Limited camera details suggest a secondary focus

Xiaomi Black Shark 4S Pro

  • Blazing-fast 120W charging (0-100% in 15 minutes)
  • Slightly more powerful Snapdragon 888+ chipset
  • Likely improved thermal management with the 888+

  • Potentially shorter battery life compared to the Red Magic 6
  • Aggressive throttling possible under sustained heavy load

Display Comparison

Both devices feature displays designed for immersive gaming, but details beyond 'infinite' contrast ratio for the Red Magic 6 are limited. The Black Shark 4S Pro likely benefits from a higher peak brightness, common in Xiaomi’s flagship displays, offering better visibility in bright conditions. While neither spec sheet details refresh rates, both brands historically prioritize high refresh rates for gaming, and the Black Shark 4S Pro’s more recent release suggests a potential advantage in panel technology and responsiveness. Bezels are likely comparable, focusing on maximizing screen real estate.

Camera Comparison

Camera details are sparse for both devices, indicating a secondary focus compared to gaming. Both are listed as having 'Photo / Video' capabilities, suggesting a standard flagship-level camera setup. The Black Shark 4S Pro, being a newer model, likely benefits from improved image processing algorithms. Without specific sensor size or aperture information, it’s difficult to make a definitive judgment, but the Black Shark 4S Pro’s more recent release suggests a more refined camera experience, even if not a primary selling point.

Performance

The core difference lies in the chipset: the Red Magic 6 utilizes the Snapdragon 888 5G, while the Black Shark 4S Pro boasts the Snapdragon 888+ 5G. The ‘+’ variant features a slightly higher clock speed (3.0 GHz vs 2.84 GHz on the X1 core), translating to a modest performance uplift in CPU-intensive tasks. Both share the same Cortex-A78 and A55 core configuration. However, the real-world impact is nuanced; the 888+’s improved thermal management is more significant than the raw clock speed difference, potentially leading to less throttling during extended gaming. Both likely utilize LPDDR5 RAM, but the Black Shark 4S Pro’s superior cooling system could allow it to maintain higher RAM speeds for longer.

Battery Life

The Red Magic 6 boasts an endurance rating of 88 hours, a significant advantage over what’s expected from a phone with a Snapdragon 888. This suggests a large battery capacity and efficient power management. The Black Shark 4S Pro, however, compensates for potentially lower battery capacity with its groundbreaking 120W wired charging. This allows for a 50% charge in just 5 minutes and a full charge in 15 minutes – a massive convenience for gamers. While the Red Magic 6’s 66W charging is respectable, it pales in comparison to the Black Shark 4S Pro’s speed. The trade-off is clear: endurance versus rapid replenishment.

Buying Guide

Buy the ZTE nubia Red Magic 6 if you need a phone that can handle marathon gaming sessions without significant throttling, and if battery life is a primary concern. Buy the Xiaomi Black Shark 4S Pro if you prioritize the absolute fastest charging speeds and want to minimize downtime between gaming sessions, even if it means potentially more aggressive thermal throttling under sustained load.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Red Magic 6 throttle significantly during prolonged gaming sessions like Genshin Impact?
While the Snapdragon 888 is known to generate heat, the Red Magic 6 incorporates a robust cooling system, including a fan and vapor chamber. This system is designed to mitigate throttling and maintain consistent performance for extended gaming periods, though some throttling is still possible under extreme conditions.
❓ How does the 120W charging on the Black Shark 4S Pro affect battery health over the long term?
Xiaomi employs charging algorithms designed to minimize battery degradation from fast charging. While extremely fast charging *can* contribute to battery wear over years of use, the Black Shark 4S Pro’s system dynamically adjusts charging speed to protect the battery’s longevity. However, it's still a factor to consider for users planning to keep the phone for 3+ years.
❓ Can either phone maintain 60fps consistently in demanding titles like PUBG Mobile at maximum settings?
Both phones are capable of running PUBG Mobile at 60fps on maximum settings, but sustained performance will depend on thermal management. The Black Shark 4S Pro’s 888+ and improved cooling system give it a slight edge in maintaining consistent frame rates during extended matches.
❓ Are the shoulder triggers on the Black Shark 4S Pro customizable for different games?
Yes, the Black Shark 4S Pro’s shoulder triggers are highly customizable. You can map them to various on-screen actions within the Black Shark’s gaming software, allowing for a more console-like gaming experience tailored to each game.
