Asus ROG Phone 5

  • Superior battery endurance (110h rating)
  • Optimized for sustained gaming performance
  • Likely higher refresh rate display for smoother gaming

  • Lower peak display brightness (806 nits)
  • Camera likely not as advanced as the Mi 11 Ultra
  • Slower charging time (52 minutes to 100%)

Xiaomi Mi 11 Ultra

  • Higher peak display brightness (943 nits)
  • Exceptional camera system
  • Fastest charging speeds (36 min wired, 39 min wireless)

  • Lower battery endurance (95h rating)
  • Potential for thermal throttling during extended gaming
  • May not prioritize gaming-specific features

Display Comparison

Both devices feature displays with an infinite (nominal) contrast ratio, but the Xiaomi Mi 11 Ultra edges out the ROG Phone 5 in peak brightness, reaching 943 nits compared to the ROG Phone 5’s 806 nits. This translates to better visibility in direct sunlight for the Mi 11 Ultra. While both utilize AMOLED technology, the ROG Phone 5’s higher refresh rate (likely 144Hz, though not specified in the data) is a significant advantage for gaming, offering smoother visuals. The lack of refresh rate data for the Mi 11 Ultra suggests a standard 120Hz panel, adequate but not class-leading for gamers.

Camera Comparison

The provided data only indicates 'Photo / Video' capabilities for both devices, lacking specifics. However, the Mi 11 Ultra is widely known for its exceptional camera system, featuring a larger main sensor and advanced image processing. While the ROG Phone 5 likely offers a competent camera, it’s not a primary focus. The Mi 11 Ultra’s camera system is geared towards capturing detailed images in various lighting conditions, with a strong emphasis on dynamic range and low-light performance. The ROG Phone 5’s camera is likely tuned for more casual use and may prioritize speed over ultimate image quality.

Performance

Both the Asus ROG Phone 5 and Xiaomi Mi 11 Ultra are powered by the Qualcomm SM8350 Snapdragon 888 5G (5 nm) chipset, featuring the same Octa-core CPU configuration. Therefore, raw CPU performance will be nearly identical. The ROG Phone 5’s advantage lies in its superior thermal design, crucial for sustaining peak performance during prolonged gaming. While the Mi 11 Ultra is a capable performer, the ROG Phone 5 is engineered to minimize throttling under heavy load, maintaining higher frame rates for longer. The ROG Phone 5’s active cooling system (not detailed in the provided data, but a key feature) is a significant differentiator.

Battery Life

The Asus ROG Phone 5 boasts an endurance rating of 110 hours, exceeding the Xiaomi Mi 11 Ultra’s 95 hours. However, this doesn’t tell the whole story. The Mi 11 Ultra compensates with significantly faster charging: 67W wired, 67W wireless, and 10W reverse wireless, achieving a full charge in just 36 minutes. The ROG Phone 5 offers 65W wired, 10W reverse wired, and takes 52 minutes for a full charge. The Mi 11 Ultra’s wireless charging capability is a unique advantage, while the ROG Phone 5’s slightly larger endurance rating suggests better overall battery life under typical usage.

Buying Guide

Buy the Asus ROG Phone 5 if you need a device specifically engineered for extended gaming sessions, prioritize raw performance and cooling, and value gaming-specific features like AirTriggers. Buy the Xiaomi Mi 11 Ultra if you prefer a top-tier camera system, appreciate fast charging (including wireless), and desire a more polished, all-around flagship experience with a stunning display.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the ROG Phone 5 overheat during long gaming sessions?
While the Snapdragon 888 is known to generate heat, the ROG Phone 5’s advanced cooling system (including likely vapor chamber and active cooling) is specifically designed to mitigate throttling and maintain stable performance during extended gaming. This is a key advantage over devices with less robust thermal solutions.
❓ How does the Mi 11 Ultra's 67W wireless charging compare to other phones?
The Mi 11 Ultra’s 67W wireless charging is exceptionally fast, significantly outpacing most competitors. It can fully charge the device in approximately 39 minutes wirelessly, making it a convenient option for users who prefer not to use cables. This is a unique selling point for the Mi 11 Ultra.
❓ Is the difference in battery endurance (110h vs 95h) noticeable in real-world use?
The difference in endurance ratings is noticeable, particularly for users who heavily utilize their phones throughout the day. The ROG Phone 5 will likely last longer on a single charge under similar usage patterns, but the Mi 11 Ultra’s faster charging can offset this difference for many users.
