Display Comparison

Both the Zenfone 7 Pro and Mi 11 Ultra feature displays with an infinite (nominal) contrast ratio, typical of OLED panels. However, the Mi 11 Ultra boasts a higher peak brightness of 943 nits compared to the Zenfone 7 Pro’s 741 nits, resulting in better visibility under direct sunlight. While both offer excellent viewing experiences, the Mi 11 Ultra’s brighter panel provides a noticeable advantage in outdoor scenarios. Refresh rate is not specified for either, but both are likely 120Hz given the flagship status and chipset capabilities.

Camera Comparison

While both phones are marketed as having excellent cameras, the Mi 11 Ultra distinguishes itself with a more advanced system. Although specific sensor details are not provided, the Mi 11 Ultra’s larger camera module suggests a larger main sensor, enabling better low-light performance and dynamic range. The Mi 11 Ultra also benefits from advanced image processing algorithms, resulting in more detailed and vibrant photos. The Zenfone 7 Pro’s flip camera is a unique feature, but the Mi 11 Ultra’s overall camera capabilities are more comprehensive.

Performance

The Xiaomi Mi 11 Ultra’s Snapdragon 888 (5nm) represents a generational leap over the Zenfone 7 Pro’s Snapdragon 865+ (7nm+). The 888’s Cortex-X1 prime core delivers a significant performance boost in single-threaded tasks, while its more efficient 5nm process contributes to improved thermal management. Although the Zenfone 7 Pro’s 865+ is still a capable chip, the 888 in the Mi 11 Ultra offers a smoother experience, particularly in demanding games and applications. Both devices utilize an octa-core CPU configuration, but the architectural improvements in the 888’s cores provide a clear advantage.

Battery Life

The Zenfone 7 Pro achieves an impressive endurance rating of 99 hours, slightly exceeding the Mi 11 Ultra’s 95 hours. However, this advantage is offset by the Mi 11 Ultra’s significantly faster charging capabilities. The Mi 11 Ultra supports 67W wired charging, achieving a full charge in just 36 minutes, and an astonishing 67W wireless charging, completing a full charge in 39 minutes. In contrast, the Zenfone 7 Pro’s 30W wired charging takes 93 minutes to reach 100%. This difference in charging speed is a major advantage for the Mi 11 Ultra, especially for users who frequently need to top up their battery.

Buying Guide

Buy the Asus Zenfone 7 Pro if you need a powerful, yet relatively compact flagship phone with a unique camera mechanism and excellent battery endurance. Buy the Xiaomi Mi 11 Ultra if you prefer a larger display, a more versatile camera system with superior zoom capabilities, and the fastest possible charging speeds, both wired and wireless.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Mi 11 Ultra suffer from significant thermal throttling during prolonged gaming sessions?
While the Snapdragon 888 is a powerful chip, it is known to generate more heat than its predecessor. The Mi 11 Ultra incorporates a sophisticated cooling system to mitigate throttling, but some performance degradation may still occur during extended, graphically intensive gaming. However, the overall gaming experience remains excellent.
❓ How does the Zenfone 7 Pro's flip camera affect the durability of the mechanism?
Asus claims the Zenfone 7 Pro’s flip camera mechanism is rated for over 200,000 flips, ensuring long-term reliability. However, it's still a mechanical component and, theoretically, could be susceptible to wear and tear over several years of heavy use. Users should exercise reasonable care to avoid applying excessive force.
❓ Is the 10W reverse wireless charging on the Mi 11 Ultra useful for topping up accessories like earbuds?
Yes, the 10W reverse wireless charging is a convenient feature for wirelessly charging accessories like earbuds or smartwatches. While not particularly fast, it provides a useful way to top up smaller devices on the go.
