My Choice

I would choose the Xiaomi 12. While the Poco X3 Pro offers a larger battery and a lower price, the Xiaomi 12 presents a significant upgrade in almost every other crucial aspect. The superior performance from the Snapdragon 8 Gen 1, the much better AMOLED display with high brightness, and the dramatically improved camera capabilities with 8K video and OIS are features that align with my usage patterns and priorities. I also value the smaller form factor and lighter weight, which make it more comfortable for daily use. Although the battery is smaller, the 67W fast charging and wireless charging options, coupled with the better power efficiency of the AMOLED display, would compensate for any reduction in battery life in my daily routine.
