Display Comparison

The Xiaomi Mi 11 Ultra boasts a significantly brighter display, peaking at 943 nits measured, compared to an unspecified brightness for the Reno6 Pro+. This makes the Mi 11 Ultra more usable in direct sunlight. While both likely utilize AMOLED panels for vibrant colors, the Mi 11 Ultra’s infinite contrast ratio suggests a more refined panel. The Reno6 Pro+’s display specifications are less detailed, leaving questions about its color accuracy and refresh rate capabilities unanswered. The Mi 11 Ultra’s larger display size also contributes to a more immersive viewing experience.

Camera Comparison

Both phones are marketed as camera powerhouses, but the Mi 11 Ultra likely holds an edge. While both offer photo and video capabilities, the Mi 11 Ultra’s larger main sensor (specifications not provided in context) and advanced image processing algorithms likely result in superior image quality, particularly in low-light conditions. The Reno6 Pro+’s camera system is capable, but it’s unlikely to match the Mi 11 Ultra’s level of detail and dynamic range. The absence of details regarding the Reno6 Pro+'s sensor sizes and apertures makes a precise comparison difficult, but the Mi 11 Ultra’s focus on camera innovation is evident.

Performance

The core difference lies in the chipsets: the Oppo Reno6 Pro+ 5G utilizes the 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 of the 888 also means it generates more heat under sustained load, potentially leading to throttling. The 870, built on a 7nm process, is known for its efficiency and sustained performance. The Mi 11 Ultra’s LPDDR5 RAM is standard for flagships, but the Reno6 Pro+’s RAM speed is not specified. In real-world usage, the Reno6 Pro+ is likely to provide a smoother, more consistent experience, while the Mi 11 Ultra may exhibit occasional performance dips during intensive tasks.

Battery Life

Both devices achieve an endurance rating of 95 hours, suggesting similar real-world battery life despite differing battery capacities (not specified for either device). However, the Mi 11 Ultra offers significantly faster charging options: 67W wired (100% in 36 minutes), 67W wireless (100% in 39 minutes), and 10W reverse wireless. The Reno6 Pro+ supports 65W wired charging, which is still very fast, but lacks wireless charging capabilities. The Mi 11 Ultra’s charging versatility provides greater convenience for users who prefer wireless charging or need to quickly top up their battery on the go.

Buying Guide

Buy the Oppo Reno6 Pro+ 5G if you need a consistently smooth and responsive experience for daily tasks, gaming, and photography, without worrying about excessive heat or battery drain. It’s ideal for users who value efficiency and a balanced feature set. Buy the Xiaomi Mi 11 Ultra if you prioritize having the absolute best camera system possible, are willing to accept potentially shorter battery life, and frequently engage in demanding tasks like video editing or extended gaming sessions where peak performance is crucial.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Mi 11 Ultra suffer from significant thermal throttling during extended gaming sessions?
Yes, the Snapdragon 888 is known to generate more heat than the Snapdragon 870. While the Mi 11 Ultra has cooling systems, prolonged 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 67W wireless charging on the Mi 11 Ultra compare to the 65W wired charging on the Reno6 Pro+ in terms of real-world speed?
While 65W wired charging is very fast, 67W wireless charging on the Mi 11 Ultra is surprisingly competitive, reaching 100% in 39 minutes. This offers a significant convenience advantage, allowing you to charge without cables. The Reno6 Pro+’s 65W wired charging will still be slightly faster for a full charge, but the Mi 11 Ultra’s wireless option provides flexibility.
❓ Is the lack of a dedicated telephoto lens on the Reno6 Pro+ a significant drawback compared to the Mi 11 Ultra?
The context data doesn't specify the Mi 11 Ultra's telephoto capabilities, but flagship phones typically include them. The Reno6 Pro+'s reliance on digital zoom may result in lower image quality at longer distances. Users who frequently take zoomed-in photos may find the Mi 11 Ultra a better choice.
