Display Comparison

Both phones feature displays with an 'Infinite' (nominal) contrast ratio, but differ significantly in brightness. The Mi 11 Ultra boasts a measured peak brightness of 943 nits, exceeding the Black Shark 4’s 694 nits. This translates to better visibility in direct sunlight for the Mi 11 Ultra. While both likely utilize AMOLED panels, the Mi 11 Ultra’s higher brightness and potential for a more color-accurate calibration make it superior for media consumption and outdoor use. The Black Shark 4’s display is still very good, but the Mi 11 Ultra offers a more premium visual experience.

Camera Comparison

The provided data only indicates 'Photo / Video' capabilities for both, lacking specifics. However, given the Mi 11 Ultra’s positioning as a flagship, it’s safe to assume a significantly more advanced camera system. The Mi 11 Ultra is known for its large 1/1.12” primary sensor, offering exceptional low-light performance and dynamic range. The Black Shark 4 likely features a more standard camera setup geared towards casual photography. The Mi 11 Ultra’s camera system is a key differentiator, appealing to users who prioritize image quality and versatility.

Performance

The core difference lies in the chipsets: the Black Shark 4 utilizes the Snapdragon 870 5G (7nm), while the Mi 11 Ultra features the Snapdragon 888 5G (5nm). The 5nm process of the 888 offers improved power efficiency and thermal performance compared to the 870’s 7nm node. While the 888 has a higher clocked Cortex-X1 prime core (2.84 GHz vs 3.2 GHz on the 870), the real-world performance difference is nuanced. The 870 is incredibly efficient and delivers excellent sustained performance, making it a strong choice for gaming. However, the 888’s Adreno 660 GPU provides a theoretical edge in graphically demanding tasks. Both phones benefit from ample RAM, though the specific configurations aren't detailed in the provided data.

Battery Life

Both phones exhibit comparable battery endurance, with ratings of 96 hours for the Black Shark 4 and 95 hours for the Mi 11 Ultra. However, their charging speeds diverge dramatically. The Black Shark 4’s 120W wired charging can fully charge the battery in just 17 minutes, a significant advantage for users who need a quick top-up. The Mi 11 Ultra, while offering 67W wired charging (with PD3.0 and QC4 support), takes 36 minutes to reach 100%. Furthermore, the Mi 11 Ultra adds 67W wireless charging and 10W reverse wireless charging, features absent on the Black Shark 4. The Black Shark 4 prioritizes speed, while the Mi 11 Ultra offers greater charging flexibility.

Buying Guide

Buy the Xiaomi Black Shark 4 if you prioritize raw gaming performance, rapid charging, and a more affordable price point. Its Snapdragon 870 and 120W charging are ideal for extended gaming sessions. Buy the Xiaomi Mi 11 Ultra if you value a top-tier camera system, a brighter and more versatile display, and the convenience of wireless charging, even if it means sacrificing some gaming-specific features and paying a premium.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Mi 11 Ultra suffer from overheating during prolonged gaming sessions?
The Snapdragon 888 is known to generate more heat than the 870. While the Mi 11 Ultra incorporates cooling solutions, extended gaming at maximum settings *may* result in some thermal throttling. However, the 5nm process and Xiaomi’s thermal management should mitigate this to a reasonable extent, offering a generally smooth gaming experience.
❓ Is the 120W charging on the Black Shark 4 safe for long-term battery health?
Xiaomi employs various safety mechanisms to protect the battery during 120W charging. While extremely fast charging *can* theoretically contribute to faster battery degradation over years of use, the benefits of rapid top-ups often outweigh this concern for most users. Xiaomi's charging algorithms are designed to minimize any potential negative impact.
❓ How does the camera performance of the Mi 11 Ultra compare to other flagship phones like the Samsung Galaxy S21 Ultra?
The Mi 11 Ultra’s camera is highly competitive with other flagship devices. Its large sensor excels in low-light conditions, and its dynamic range is excellent. While subjective preferences vary, many reviewers consider the Mi 11 Ultra’s camera to be on par with, or even superior to, the Galaxy S21 Ultra in certain scenarios, particularly in challenging lighting.
