ZTE nubia RedMagic 3S

  • Exceptional battery endurance (115h)
  • Aggressive cooling system for sustained performance
  • Potentially better thermal throttling management

  • Slower charging speed (18W)
  • Limited camera information

Xiaomi Black Shark 2 Pro

  • Faster charging speed (27W)
  • Likely more refined camera system
  • Potentially better display color accuracy

  • Lower endurance rating compared to RedMagic 3S
  • May be more prone to thermal throttling under sustained load

Display Comparison

Both phones utilize displays optimized for gaming, but key differences exist. The RedMagic 3S boasts a measured peak brightness of 479.7 nits, providing adequate visibility. While the Black Shark 2 Pro’s display specs aren’t provided, Xiaomi historically focuses on color accuracy and vibrancy. The RedMagic 3S’s larger focus on cooling may necessitate a slightly less aggressive display panel to manage thermal output. Gamers sensitive to flicker will need to investigate PWM dimming rates on both devices, as this data is unavailable, but is a critical factor for eye strain during long sessions.

Camera Comparison

Camera performance is a secondary consideration for gaming phones, and the provided data is limited to 'Photo / Video' for the RedMagic 3S. The Black Shark 2 Pro likely offers a more versatile camera system, typical of Xiaomi’s flagship devices. Without sensor size or aperture information, a direct comparison is impossible. However, users should temper expectations; these phones prioritize gaming over photographic excellence. The inclusion of a 2MP macro lens on either device is largely a marketing gimmick and unlikely to deliver significant value.

Performance

Both the RedMagic 3S and Black Shark 2 Pro are powered by the Qualcomm Snapdragon 855+ (7nm), featuring an identical CPU configuration: Octa-core (1x2.96 GHz Kryo 485 & 3x2.42 GHz Kryo 485 & 4x1.8 GHz Kryo 485). The performance difference will therefore hinge on thermal management. The RedMagic 3S’s aggressive cooling solution – including a fan – is designed to prevent throttling under sustained load, potentially allowing it to maintain peak performance for longer. The Black Shark 2 Pro relies on liquid cooling, which is effective but may not match the RedMagic’s active cooling in extreme scenarios. RAM speeds (LPDDR4X) are likely similar, but not specified in the provided data.

Battery Life

The RedMagic 3S boasts an endurance rating of 115 hours, indicating exceptional battery life. This is a significant advantage for gamers who want to play for extended periods without needing to recharge. The Black Shark 2 Pro compensates with 27W wired charging, significantly faster than the RedMagic 3S’s 18W QC4 charging. This means the Black Shark 2 Pro can replenish its battery much more quickly, but the RedMagic 3S will likely last longer on a single charge. The actual 0-100% charge times will vary, but the Black Shark 2 Pro will likely achieve a full charge in under an hour, while the RedMagic 3S will take considerably longer.

Buying Guide

Buy the ZTE nubia RedMagic 3S if you need maximum battery life for extended gaming marathons and value sustained performance over the fastest possible charging speeds. Buy the Xiaomi Black Shark 2 Pro if you prioritize quick top-ups and frequently find yourself needing to recharge mid-session, and appreciate a slightly more refined software experience.

Frequently Asked Questions

❓ Will the Snapdragon 855+ in either phone struggle with demanding games like Genshin Impact?
While the Snapdragon 855+ is a powerful chip, demanding titles like Genshin Impact can push it to its limits. The RedMagic 3S’s superior cooling system is more likely to maintain stable frame rates for longer periods, minimizing throttling and ensuring a smoother gaming experience. The Black Shark 2 Pro may experience more noticeable performance drops during extended gameplay.
❓ How much does the active cooling fan on the RedMagic 3S impact battery life?
The active cooling fan does consume power, but ZTE has optimized its operation to minimize the impact on battery life. The fan is not constantly running; it activates when the phone reaches a certain temperature threshold. While it will reduce overall endurance slightly, the benefit of sustained performance outweighs the battery cost for serious gamers.
❓ Does the Black Shark 2 Pro’s 27W charging significantly reduce battery degradation over time?
Faster charging *can* contribute to slightly increased battery degradation over the long term, but modern battery management systems mitigate this effect. The convenience of quickly topping up the Black Shark 2 Pro’s battery likely outweighs the minimal potential impact on long-term battery health.
