My Choice and Why

If I were choosing between these two phones, I would pick the Xiaomi Poco X4 Pro 5G. My decision is based on several factors that align with my typical use case:

1. Display Experience: I value a smoother display experience. The 120Hz refresh rate on the X4 Pro 5G would make scrolling and animations feel more fluid and responsive.

3. Charging Speed: I also appreciate fast charging because I value spending less time plugged into the wall.
4. Performance: The slightly better performance from the newer Snapdragon chipset makes this a slightly snappier phone.
5. Cost: I like that the X4 Pro 5G has a slightly cheaper base model (64GB version).
6. Build Quality: I prefer a screen with glass protection.

While the Galaxy A72 has a better camera setup with the telephoto lens, it isn't as important to me as the other points. Therefore the Xiaomi Poco X4 Pro 5G has a better set of features for the way I use my phone.
