Display Comparison
Both devices feature 'Infinite' contrast ratios, a marketing term indicating excellent black levels. However, the Redmi K20 Pro boasts a measured peak brightness of 643 nits, potentially offering better visibility in direct sunlight compared to the S10+'s 4.514 contrast ratio in sunlight, which is a different metric. While both displays are excellent, the K20 Pro’s higher peak brightness gives it a slight edge for outdoor use. The S10+’s display, however, benefits from Samsung’s established color calibration expertise, likely resulting in more accurate colors out of the box.
Camera Comparison
Both phones offer capable camera systems, but details beyond 'Photo/Video' are limited. The S10+ likely benefits from Samsung’s advanced image processing algorithms, known for vibrant colors and scene optimization. The K20 Pro, while potentially lacking the same level of software refinement, benefits from the Snapdragon 855’s powerful ISP (Image Signal Processor). Without specific sensor size or aperture data, it’s difficult to definitively declare a winner. However, the S10+’s inclusion of a variable aperture lens on its main camera provides greater control over depth of field and low-light performance, a feature absent on the K20 Pro.
Performance
The chipset configuration is a key differentiator. The Redmi K20 Pro universally ships with the Qualcomm Snapdragon 855 (7nm), while the Galaxy S10+ varies – utilizing the Exynos 9820 (8nm) in EMEA/LATAM regions and the Snapdragon 855 (7nm) in USA/China. The 7nm process node of the Snapdragon 855 generally translates to better power efficiency and thermal performance compared to the 8nm Exynos 9820. The CPU architecture also differs; the S10+’s Exynos uses custom Mongoose M4 cores alongside Cortex-A75/A55, while the K20 Pro’s Snapdragon 855 utilizes Kryo 485 cores. In real-world usage, the K20 Pro’s consistent Snapdragon 855 configuration provides a more predictable and often superior performance experience, especially in sustained workloads. Users with the Exynos variant of the S10+ may experience more noticeable throttling under heavy load.
Battery Life
The Redmi K20 Pro’s endurance rating of 103 hours significantly surpasses the Galaxy S10+'s 91 hours. This difference is attributable to a combination of factors, including the more efficient Snapdragon 855 chipset and potentially a larger battery capacity (though specific mAh figures are not provided). The K20 Pro also supports 27W wired charging with Quick Charge 4 (QC4), enabling faster charging speeds than the S10+'s 15W wired charging and 15W wireless charging (Qi/PMA). The S10+’s inclusion of 4.5W reverse wireless charging is a convenience feature the K20 Pro lacks, allowing it to charge accessories like earbuds.
Buying Guide
Buy the Xiaomi Redmi K20 Pro if you need uncompromising performance for gaming and demanding tasks, and prioritize long battery life above all else. You’ll benefit from a faster processor and significantly better endurance. Buy the Samsung Galaxy S10+ if you prefer a more refined software experience, value wireless charging and reverse wireless charging capabilities, and are invested in the Samsung ecosystem. The S10+ offers a more premium feel and a broader feature set, albeit at a higher initial cost.
