My Choice

If I were choosing between these two phones, I would select the Xiaomi 12X. While the Poco M3 boasts a larger battery, the overall user experience of the 12X is far superior. The AMOLED display with its 120Hz refresh rate and higher brightness is a game-changer for daily use and media consumption. Moreover, the significantly faster processor provides a much smoother and responsive experience, crucial for multitasking and gaming. The advanced camera system with features like OIS and 8K video is something I greatly value. Although the battery life might be slightly shorter compared to the Poco M3, the 67W fast charging makes up for that with dramatically reduced charging times. For me, the trade-offs of battery life are outweighed by the substantial performance, display and camera upgrades that the 12X offers.
