My Choice and Why

If I were choosing between these two phones, I'd lean towards the Xiaomi 12 Pro. While the Samsung Galaxy A55 is a very capable phone and offers a newer Android experience, for me the sheer difference in performance, display quality, and camera capabilities of the Xiaomi 12 Pro is too significant to ignore. I'm a power user who often edits photos and videos on the go, and the enhanced performance and camera features of the Xiaomi would make my daily work much smoother. The 120W charging would be a game-changer, allowing me to quickly top up my phone during busy days. While the A55 offers a newer operating system, the raw power and exceptional visual experience of the Xiaomi are more important for my needs. For me the trade offs of slighty less battery life and older software are far outweighed by the performance improvements.
