Display Comparison

The Xiaomi Mi 11 Ultra’s display boasts a measured peak brightness of 943 nits, offering excellent visibility in direct sunlight. While the Reno6 Pro+’s display specs aren’t provided, Oppo typically utilizes high-quality AMOLED panels. The Mi 11 Ultra’s infinite contrast ratio (nominal) is standard for AMOLED technology, delivering deep blacks and vibrant colors. However, without knowing the Reno6 Pro+'s display characteristics, it's difficult to definitively declare a winner; the Mi 11 Ultra’s brightness is a clear advantage.

Camera Comparison

Both devices are marketed as camera-centric, but the Mi 11 Ultra’s camera system is more ambitious. While both are listed as having Photo/Video capabilities, the Mi 11 Ultra’s sensor size and lens configuration are likely more advanced, though specific details are missing. The Mi 11 Ultra’s larger sensor will capture more light, resulting in better low-light performance and dynamic range. The Reno6 Pro+ likely focuses on computational photography and software enhancements to compete, but the Mi 11 Ultra’s hardware advantage is significant. We can assume the Mi 11 Ultra has a more versatile camera system.

Performance

The core difference lies in the chipsets: the Oppo Reno6 Pro+ 5G utilizes the Qualcomm Snapdragon 870 5G (7nm), while the Xiaomi Mi 11 Ultra features the Snapdragon 888 5G (5nm). The 888, with its Cortex-X1 prime core clocked at 2.84 GHz, theoretically offers higher peak performance. However, the 5nm process node of the 888 also means it generates more heat. The Snapdragon 870, built on a 7nm process, is known for its efficiency and sustained performance. The Mi 11 Ultra’s CPU architecture (Cortex-X1, A78, A55) is more advanced, but the Reno6 Pro+'s thermal management could lead to more consistent frame rates during extended gaming sessions. The Reno6 Pro+’s efficiency is a key advantage for everyday use.

Battery Life

Both phones achieve an endurance rating of 95 hours, suggesting similar real-world battery life despite differing battery capacities (not specified for the Reno6 Pro+). However, the Mi 11 Ultra’s charging capabilities are more comprehensive: 67W wired (36 minutes to 100%), 67W wireless (39 minutes to 100%), 10W reverse wireless. The Reno6 Pro+ offers 65W wired charging, which is competitive, but lacks wireless charging options. The Mi 11 Ultra’s faster wireless charging and reverse wireless capabilities provide greater convenience and flexibility.

Buying Guide

Buy the Oppo Reno6 Pro+ 5G if you need a consistently responsive phone for daily tasks, gaming, and photography without worrying about overheating or excessive battery drain. It’s ideal for users who value a balanced experience and don't necessarily need the absolute best specs on paper. Buy the Xiaomi Mi 11 Ultra if you prioritize camera versatility above all else, frequently shoot professional-quality photos and videos, and are willing to accept potentially shorter battery life and occasional performance throttling during intensive tasks.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Mi 11 Ultra suffer from significant thermal throttling during prolonged gaming sessions?
Yes, the Snapdragon 888 is known to generate more heat than the Snapdragon 870. While the Mi 11 Ultra has cooling solutions, extended gaming or demanding tasks can lead to noticeable throttling, reducing sustained performance. The Reno6 Pro+ 5G, with its Snapdragon 870, is less prone to this issue.
❓ How does the 65W charging on the Reno6 Pro+ compare to the 67W charging on the Mi 11 Ultra in real-world usage?
While the difference of 2W seems minor, the Mi 11 Ultra’s 67W charging is slightly faster, achieving a full charge in 36 minutes compared to an unspecified time for the Reno6 Pro+. However, both offer very rapid charging speeds, and the difference is unlikely to be significant for most users.
❓ Is the lack of a telephoto lens on the Reno6 Pro+ a major disadvantage compared to the Mi 11 Ultra?
Without specific camera specs for the Reno6 Pro+, it's difficult to say definitively. However, the Mi 11 Ultra likely includes a dedicated telephoto lens for improved zoom capabilities. If you frequently use zoom, the Mi 11 Ultra is the better choice. Otherwise, the Reno6 Pro+'s computational photography may compensate.
