  2. How important is battery life? The OnePlus 12 likely offers longer battery life.
  3. What is your budget? The Xiaomi 14 is generally more affordable.

My Choice: OnePlus 12

While the Xiaomi 14 offers a compelling compact design and impressive slow-motion capabilities, the OnePlus 12's larger, sharper, and brighter display, coupled with its larger battery and more RAM, makes it a more appealing overall package for my needs. I prioritize a great screen for media consumption and productivity, and the extra battery life and RAM are crucial for my usage patterns. The slight increase in size and weight is a trade-off I am willing to make for these benefits. Although lacking the extreme slow-motion capabilities of the Xiaomi 14, the OnePlus 12 still provides sufficient video recording features for my typical use.
