What I Would Choose and Why
I would choose the Xiaomi 12T. While the Samsung Galaxy A02s might be tempting due to its lower price, the sheer difference in performance, display quality, camera capabilities, and charging speed makes the Xiaomi 12T a much more compelling option.
The A02s, being a budget phone, has significant limitations in almost every aspect. Its low-resolution display, slow processor, and basic camera system would quickly become frustrating for daily usage beyond simple calls and texts. The 12T is much faster, has a significantly better display for watching videos, and takes significantly better pictures and videos - and these benefits drastically outweigh the extra price.
While the A02s has a marginally lighter weight, the real-world improvements to user experience that the 12T offers, such as the smooth 120Hz refresh rate, high quality screen and its superior camera system, make it a worthwhile investment. Its ability to charge much faster is also extremely useful for everyday convenience. The 12T will offer a far more satisfying user experience over a longer lifespan due to its much more advanced hardware and longer software update support.
