Xiaomi Black Shark 4

  • Incredibly fast 120W charging
  • Longer battery endurance
  • More efficient Snapdragon 870 for sustained gaming

  • Likely inferior camera system
  • Lacks wireless charging

OnePlus 9 Pro

  • Superior camera system with advanced features
  • Versatile charging options (wired, wireless, reverse wireless)
  • More refined software experience

  • Shorter battery endurance
  • Snapdragon 888 can throttle under sustained load

Display Comparison

Both devices feature excellent displays, but with different priorities. The OnePlus 9 Pro boasts a slightly brighter panel at 859 nits measured, compared to the Black Shark 4’s 694 nits. While the difference is noticeable, both are perfectly usable outdoors. The OnePlus 9 Pro likely utilizes LTPO technology (though not explicitly stated in the data) for adaptive refresh rates, potentially improving battery efficiency. The Black Shark 4, geared towards gaming, likely prioritizes refresh rate and response time over absolute peak brightness, though specific panel technology isn't detailed. Both displays have an 'Infinite' (nominal) contrast ratio, typical for OLED panels.

Camera Comparison

The provided data only indicates both phones have 'Photo / Video' capabilities, lacking specifics. Given OnePlus’s history and the 9 Pro’s positioning, it almost certainly features a more sophisticated camera system with larger sensors, advanced image processing, and features like Hasselblad color calibration. The Black Shark 4 likely prioritizes functionality over outright image quality, focusing on capturing gameplay or quick snapshots. Without sensor size or aperture data, it’s difficult to make a precise comparison, but the OnePlus 9 Pro is expected to deliver significantly better still photography and videography.

Performance

The core difference lies in the chipsets. The OnePlus 9 Pro is powered by the Snapdragon 888 (5nm), while the Black Shark 4 utilizes the Snapdragon 870 (7nm). The 888, with its Cortex-X1 prime core, offers a theoretical performance advantage, particularly in single-core tasks. However, the 870’s larger process node means it generally runs cooler and more efficiently, potentially leading to less thermal throttling during prolonged gaming. The Black Shark 4’s CPU configuration (3x2.42 GHz Kryo 585) is optimized for sustained performance, while the 9 Pro’s (3x2.42 GHz Cortex-A78) prioritizes peak performance. Both phones utilize Octa-core CPUs, but the architectural differences impact real-world performance and thermal behavior.

Battery Life

The Black Shark 4 boasts an endurance rating of 96 hours, exceeding the OnePlus 9 Pro’s 86 hours. This is partially due to the more efficient Snapdragon 870 and potentially a larger battery capacity (not specified in the data). However, the OnePlus 9 Pro compensates with significantly faster charging: 65W wired (29 minutes to 100%), 50W wireless (43 minutes), and 5W reverse wireless. The Black Shark 4’s 120W wired charging is incredibly fast (17 minutes to 100%), but lacks wireless charging options. The Black Shark 4’s longer endurance is beneficial for users who prioritize minimizing charging frequency, while the OnePlus 9 Pro offers convenience with its versatile charging options.

Buying Guide

Buy the Xiaomi Black Shark 4 if you need uncompromising gaming performance, exceptionally fast 120W charging, and a long-lasting battery for extended play sessions. Buy the OnePlus 9 Pro if you prefer a balanced flagship experience with a top-tier camera, a vibrant display, and a refined software experience, even if it means sacrificing some raw gaming horsepower and charging speed.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the OnePlus 9 Pro overheat during extended gaming sessions?
The Snapdragon 888 is known to generate more heat than the Snapdragon 870. While the OnePlus 9 Pro has cooling solutions, prolonged gaming at maximum settings can lead to thermal throttling, reducing sustained performance. The Black Shark 4, with its 870 and potentially more aggressive cooling, is likely to maintain higher frame rates for longer periods.
❓ How does the 120W charging on the Black Shark 4 affect battery health over time?
While 120W charging is incredibly fast, concerns about long-term battery degradation are valid. Xiaomi likely employs charging algorithms to mitigate this, such as reducing charging speed as the battery nears full capacity. However, consistently using ultra-fast charging *may* accelerate battery wear compared to slower charging methods.
❓ Is the camera on the Black Shark 4 sufficient for casual photography?
The Black Shark 4's camera is likely adequate for casual snapshots and social media sharing. However, it won't match the image quality, dynamic range, or feature set of the OnePlus 9 Pro's camera system, which benefits from advanced sensors and image processing.
❓ Does the OnePlus 9 Pro support high frame rate gaming (90fps or higher) in popular titles like PUBG?
The OnePlus 9 Pro is capable of running PUBG Mobile at high frame rates (90fps or higher) depending on the game settings and device temperature. However, achieving consistently high frame rates may require adjusting graphics settings to prevent overheating.
