My Choice

If I were choosing between these two phones, I would choose the Samsung Galaxy Z Flip3 5G.

Here's why:

While the Redmi 9T has the advantage of a much larger battery and lower price, my preference leans towards a premium experience. The Z Flip3's foldable design, superior performance, higher refresh rate display, and better camera system are significant upgrades that justify its higher cost, in my view. The convenience of a more compact device when folded also aligns better with my usage needs. I value the benefits of the better performance for smoother multitasking and a more enjoyable user experience which I would benefit from more than I would from longer battery life. While I do appreciate a long battery life, it is still adequate on the Z Flip3 5G, especially since I am not always away from a charging source. Ultimately, the innovative and premium nature of the Z Flip3 combined with its superior performance and camera capabilities, outweigh the value and battery life benefits of the Redmi 9T for my personal usage scenario.
