As a tech journalist and someone who dives into the nitty-gritty of mobile technology, I value top-tier performance, cutting-edge features, and versatility. While the Xiaomi 12X is a solid device with good value, the S23 Ultra ticks more of the boxes that align with my priorities:

  • Performance: The Snapdragon 8 Gen 2 is a clear winner for performance-intensive tasks, which includes daily use, heavy multitasking, and gaming.

  • Display Quality: I'm spending a lot of time on my phone so the larger, sharper, brighter screen is a huge plus.
  • Software & Updates: The S23 Ultra's long-term software support will provide more value over time.
  • Future-Proofing: The latest version of Bluetooth, and superior processor means it will stay up to date longer, even if the price is high.

In short, although the Xiaomi 12X offers a fantastic experience for the price, the Samsung Galaxy S23 Ultra better aligns with my use cases and offers a more substantial array of benefits that justifies its higher price point.
