4. Buying Decision Framework

Here are three questions to help you decide:

  1. What is your priority: Performance or Battery Life?
    • If performance is paramount, choose the Xiaomi 12X.
    • If you value battery life above all else, the Realme C65 might be better for you.
  2. How important is display quality?
    • If you want the best display quality, the Xiaomi 12X with its AMOLED screen is a clear winner.
    • If a larger screen is enough, the Realme C65 is satisfactory.
  3. What is your budget?
    • The Xiaomi 12X is a premium phone with a price tag to match, while the Realme C65 is a budget-friendly device. Scenario Recommendations:
      • The Power User: If you plan on gaming or running high-intensity apps the Xiaomi 12X is the only option. The much faster chipset, better GPU, and better RAM will give an incomparably smoother experience.
      • The Photographer: If photography is important to you, the camera on the Xiaomi 12X is far superior. The wider sensor, dedicated wide-angle and macro lenses allow you to take better pictures and be more creative.
      • The Everyday User: If you're more concerned with day-to-day tasks, streaming, and need a device that will last all day the Realme C65 will get the job done. But the experience will be noticeably worse with slower performance and inferior screen quality.

Final Thoughts: What I Would Choose

Given my preference for performance, display quality, and superior camera capabilities, I would choose the Xiaomi 12X. While the Realme C65 offers a bigger battery and a more up-to-date Android version, the performance and experience offered by the Xiaomi 12X are far more important to me. The difference in daily usage between these devices will be huge, with the Xiaomi 12X offering a smoother and more enjoyable experience.

The superior AMOLED display, the powerful Snapdragon 870 chipset, and a much more versatile camera system would significantly enhance my daily usage, making the higher price tag worthwhile. I am willing to trade off a little battery for a much superior experience.

My choice is also heavily influenced by the unknown brightness of the C65, and its use of an older chipset, and very basic audio. This all adds up to an experience that would be inferior to the 12X.
