Display Comparison

Both devices feature a contrast ratio of 1487:1, suggesting similar visual characteristics in terms of black levels and color depth. However, the Redmi Note 8 2021 boasts a measured peak brightness of 620 nits, significantly exceeding what we'd expect from the A11s based on its market positioning. This brighter display translates to better outdoor visibility. While both lack high refresh rates, the Redmi Note 8 2021’s higher brightness provides a more pleasant viewing experience in various lighting conditions.

Camera Comparison

Both phones offer 'Photo / Video' capabilities, but the context data lacks specifics. Given the price bracket, we can assume both rely on relatively basic camera sensors. The Redmi Note 8 2021, historically, has offered more competitive camera performance in its segment, likely due to MediaTek’s image signal processor (ISP) capabilities. Without detailed sensor information, it’s difficult to make a definitive judgment, but the Redmi Note 8 2021 likely provides a more versatile camera experience.

Performance

The core difference lies in the chipsets. The Redmi Note 8 2021’s MediaTek Helio G85 (12nm) features a more powerful CPU configuration – 2x2.0 GHz Cortex-A75 cores and 6x1.8 GHz Cortex-A55 cores – compared to the Oppo A11s’ Qualcomm Snapdragon 460 (11nm) with its 4x1.8 GHz Kryo 240 and 4x1.6 GHz Kryo 240 setup. The Helio G85’s Cortex-A75 cores offer a substantial performance uplift in single-core tasks, while the 12nm process allows for higher clock speeds. Although the Snapdragon 460 benefits from a slightly smaller node size, the architectural advantages of the Helio G85 translate to a more responsive user experience, particularly in gaming and app loading times.

Battery Life

Both the Oppo A11s and Xiaomi Redmi Note 8 2021 share an endurance rating of 102 hours and 18W wired charging. This suggests comparable battery life under similar usage scenarios. The 18W charging, while not exceptionally fast, should provide a reasonable recharge time. The efficiency of the respective chipsets will play a role in real-world battery performance, but the similar endurance rating indicates a balanced approach to power consumption.

Buying Guide

Buy the Oppo A11s if you prioritize a Qualcomm chipset and are looking for a reliable, basic smartphone experience for everyday tasks like calling, texting, and light social media use. Buy the Xiaomi Redmi Note 8 2021 if you prefer a more capable processor for occasional gaming or demanding applications, and value the potential for slightly smoother multitasking and a brighter display.
