What I Would Choose
If I were choosing between these two phones, I would select the Xiaomi Redmi Note 12 4G.
My Reasoning:
While the vivo V21 5G offers excellent front-camera capabilities, which is a compelling feature, I personally value a long-lasting battery, a bright and smooth display, and the added convenience of reverse charging more. The 120Hz refresh rate of the Xiaomi provides a noticeably smoother experience for daily usage and the increased brightness will be more practical in sunny outdoor environments, making the phone easier to use in daily life. I do not often use front-facing camera features, which makes it less important for me, while having a good screen and better battery is something that I use daily. Additionally, the better screen protection of the Xiaomi is also a deciding factor, as it means it will last longer.
My use case aligns more with general use, media consumption, and outdoor use, which are the strengths of the Xiaomi Redmi Note 12 4G. The minor hit in selfie quality is something I can easily compensate for, while the benefits provided by the Xiaomi will be more valuable to me on a day-to-day basis.
