My Choice and Explanation
If I had to choose between these two phones, I would choose the vivo V21 5G. While the Xiaomi Redmi 12 offers a larger battery and a more recent Android version, the V21 5G's superior camera, display and performance are more aligned with my priorities. The significant difference in front camera quality (44MP vs 8MP) is a key factor, as I often take selfies. Furthermore, the AMOLED display and faster processor will provide a more enjoyable experience for my usage scenarios.
The trade-off in battery life is acceptable to me, as I prefer better performance and display quality. The slimmer design is also a plus for portability. While the Redmi 12's reverse charging is a nice feature, it isn't essential for my needs, and I would personally value the quality of the photos and videos more.
