  • Potentially more balanced software experience.

  • Slower charging compared to the Black Shark 3 Pro.
  • Limited camera information suggests it's not a primary focus.

Xiaomi Black Shark 3 Pro

  • 65W charging delivers a full charge in just 38 minutes.
  • 18W magnetic wireless charging adds convenience.
  • Likely superior thermal management for sustained gaming.

  • Potentially more aggressive thermal throttling under heavy load.
  • Gaming-focused design may not appeal to all users.

Display Comparison

Both devices utilize panels capable of displaying vibrant colors, but detailed display specifications beyond the iQOO 3 5G’s measured 848 nits peak brightness are unavailable. Given the Black Shark 3 Pro’s gaming focus, it likely prioritizes a high refresh rate (likely 90Hz or 120Hz, based on market trends for the time) to enhance visual fluidity. The iQOO 3 5G’s ‘Infinite’ contrast ratio is a nominal specification, common in OLED displays, and doesn’t provide a comparative advantage without further data. The absence of LTPO technology in either device suggests both will rely on traditional refresh rate switching, potentially impacting battery life during variable content.

Camera Comparison

The provided data only indicates both phones feature photo and video capabilities, lacking specifics on sensor size, aperture, or image processing. Given the Black Shark 3 Pro’s broader appeal, it may incorporate a more versatile camera system. However, without detailed specifications, it’s difficult to assess a clear advantage. The absence of information suggests neither phone prioritizes camera performance as a key selling point, focusing instead on gaming capabilities.

Performance

Both the iQOO 3 5G and Black Shark 3 Pro are powered by the Qualcomm SM8250 Snapdragon 865 5G (7 nm+), featuring an identical CPU configuration: an octa-core setup with 1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55 cores. This means raw processing power will be nearly identical. However, the Black Shark 3 Pro likely employs a more aggressive cooling solution – a common feature in gaming phones – to sustain peak performance for longer durations. While both benefit from 5G connectivity, sustained gaming performance will hinge on the effectiveness of their respective thermal management systems, a metric not provided in the source data.

Battery Life

The iQOO 3 5G boasts an endurance rating of 118 hours, suggesting respectable battery life. However, the Black Shark 3 Pro compensates for potentially higher power draw from its gaming-centric features with significantly faster charging: 65W wired, achieving 100% charge in 38 minutes, alongside 18W magnetic wireless charging. The iQOO 3 5G’s 55W charging, reaching 50% in 15 minutes, is still fast, but the Black Shark 3 Pro’s complete charge time is substantially quicker, offering a crucial advantage for gamers who need to quickly return to action.

Buying Guide

Buy the vivo iQOO 3 5G if you prioritize a slightly more refined software experience and a potentially more balanced daily driver. Buy the Xiaomi Black Shark 3 Pro if you are a dedicated mobile gamer who values the fastest possible charging speeds and a more overtly gaming-focused design, and are willing to accept a potentially more aggressive thermal profile under sustained load.

Frequently Asked Questions

❓ How does the Black Shark 3 Pro's charging speed impact extended gaming sessions?
The Black Shark 3 Pro's 65W charging is a game-changer for gamers. Being able to fully recharge the device in under 40 minutes minimizes downtime between sessions, allowing for more uninterrupted gameplay. This is particularly beneficial for competitive gamers who need to maximize their practice time.
❓ Will the Snapdragon 865 in the iQOO 3 5G experience significant throttling during prolonged gaming?
While the Snapdragon 865 is a powerful chipset, it's prone to thermal throttling under sustained load. The iQOO 3 5G's cooling solution, which isn't detailed in the provided data, will determine how effectively it manages heat. The Black Shark 3 Pro, designed specifically for gaming, likely has a more robust cooling system, potentially mitigating throttling to a greater extent.
❓ Does the Black Shark 3 Pro's gaming focus compromise its usability as a daily driver?
The Black Shark 3 Pro's design and software lean heavily into gaming aesthetics. While it functions perfectly well as a daily driver, its more aggressive look and gaming-centric features might not appeal to users seeking a more understated smartphone experience. The iQOO 3 5G offers a potentially more balanced approach.
