My Choice: Xiaomi Redmi 12 5G

While the Realme C55 offers advantages like a brighter display, faster charging, and a slightly better camera setup, I would choose the Xiaomi Redmi 12 5G. The deciding factor for me is the more modern and efficient Snapdragon 4 Gen 2 processor. This translates to better long-term performance, improved battery life, and potentially better thermal management during extended use and gaming. The inclusion of 5G connectivity ensures future-proofing, and the Adreno 613 GPU promises a smoother gaming experience compared to the Mali-G52. Although the Redmi 12 5G lacks 60fps video recording and has slower charging, these are trade-offs I'm willing to accept for the superior performance and future-proof connectivity. The slightly heavier weight and larger size are minor inconveniences in comparison. Ultimately, the Redmi 12 5G offers a more compelling overall package for my needs, focusing on long-term performance and connectivity.
