4. Buying Decision Framework

Here are three questions to help you decide:

  1. What is my main use case? If you prioritize performance, camera quality, and connectivity, the Xiaomi 12 is the clear choice. If you only need a device for basic tasks and media consumption, the realme 8 might suffice.
  2. How important is screen size versus portability? If you prefer a large display for immersive content and are fine with a larger device, the realme 8 might suit you. If you prefer a compact phone for one-handed use, go with the Xiaomi 12.

  • Scenario 2: Photography Enthusiast: The Xiaomi 12 offers a superior camera system with more features, and significantly better video recording.
  • Scenario 3: Budget Buyer with Basic Needs: The realme 8 could be the better choice, depending on pricing and availability, for more basic tasks, though it seems to lack any of the premium features of the Xiaomi 12.

My Choice

Given the data provided, I would choose the Xiaomi 12. While there is limited information about the realme 8, and the realme 8 has a larger screen and the latest Android version, the Xiaomi 12 is the clearly better device for me, and here's why:

  • Performance: The Snapdragon 8 Gen 1 is a powerhouse, and I do like to play mobile games and do some light video editing on my phone.
  • Camera: The camera system is vastly more versatile, with higher video resolutions, a wide-angle lens, and a macro lens.
  • Display: Despite being slightly smaller, the display is much brighter, making it much better for outdoor use.
  • Charging: Fast charging is a significant convenience, reducing downtime and being ready to go on short notice.
  • Build Quality: With Gorilla Glass Victus, the Xiaomi 12 offers excellent screen protection.

While the realme 8 might be appealing to a very specific user base, especially if the price is a factor, the Xiaomi 12 is the more versatile, technologically superior device for most users. The realme 8 data is largely lacking, leading me to believe the Xiaomi 12 is the far superior device, even without any other information.
