OnePlus 7 Pro
- 90Hz Fluid AMOLED display for smoother visuals
- Polished and user-friendly OxygenOS software
- Consistently bright display (616 nits)
- Slightly slower processor (Snapdragon 855)
- Charging speed potentially slower than K20 Pro Premium
Xiaomi Redmi K20 Pro Premium
- Faster processor (Snapdragon 855+)
- Faster charging with QC4 support (27W)
- Potentially better value for performance
- MIUI software can be more intrusive
- Display likely lacks the 90Hz refresh rate of the OnePlus 7 Pro
Display Comparison
The OnePlus 7 Pro boasts a 6.67-inch Fluid AMOLED display capable of reaching 616 nits of peak brightness, ensuring excellent visibility even outdoors. While the Redmi K20 Pro Premium’s display specifications aren’t explicitly provided, Xiaomi typically prioritizes vibrant colors and high contrast ratios in their AMOLED panels. The OnePlus 7 Pro’s 90Hz refresh rate, a standout feature at the time, provides a noticeably smoother scrolling experience compared to the standard 60Hz likely found on the K20 Pro Premium. This difference is particularly noticeable for gamers and frequent social media users.
Camera Comparison
Both phones feature capable camera systems, but detailed sensor information is limited. Both are described as having Photo/Video capabilities. The Redmi K20 Pro Premium likely benefits from the slightly more powerful chipset for image processing, potentially leading to faster capture times and improved low-light performance. Without specific sensor size or aperture data, it’s difficult to definitively declare a winner, but the K20 Pro Premium’s processing advantage is a likely differentiator. It's important to note that the inclusion of a 2MP macro camera on many phones of this era often provides minimal real-world benefit.
Performance
Both devices are powered by the Qualcomm Snapdragon 855, but the Redmi K20 Pro Premium features the Snapdragon 855+, a slightly overclocked variant. The K20 Pro Premium’s CPU clocks at 2.96 GHz versus the 7 Pro’s 2.84 GHz, offering a marginal performance boost in CPU-intensive tasks. The difference is further amplified by the K20 Pro Premium’s slightly faster Kryo 485 cores at 1.8 GHz compared to the 7 Pro’s 1.78 GHz. While not a massive leap, this translates to quicker app loading times and smoother multitasking. Thermal management will be key; the 855 series was known to throttle under sustained load, and the 855+’s higher clocks could exacerbate this issue.
Battery Life
The OnePlus 7 Pro achieves an endurance rating of 85 hours, indicating solid battery life. The Redmi K20 Pro Premium’s battery capacity isn’t specified, but its 27W wired charging with Quick Charge 4 (QC4) support is faster than the OnePlus 7 Pro’s 30W wired charging. While the OnePlus 7 Pro’s charging wattage is higher, QC4’s efficiency and compatibility could result in faster overall charging times for the K20 Pro Premium. The difference in battery life will depend heavily on usage patterns, but the K20 Pro Premium’s faster charging offers a convenience advantage.
Buying Guide
Buy the OnePlus 7 Pro if you need a polished, user-friendly experience with a consistently bright display and a brand known for timely software updates (even post-launch). Buy the Xiaomi Redmi K20 Pro Premium if you prioritize raw performance, faster charging speeds, and are comfortable with Xiaomi’s MIUI software, potentially offering more features for the price.
