4. Buying Decision Framework

Here are some questions to ask yourself:

  1. How important is performance to me? If you want a phone that can handle demanding games and apps without breaking a sweat, the GT Master is the clear winner.
  2. How much do I value display quality? The AMOLED screen on the GT Master is far superior to the LCD on the Redmi 12.
  3. Is battery life or fast charging more important? The Redmi 12 will last longer, but the GT Master charges incredibly quickly.

Scenario-Based Recommendations:

  • Scenario 1: Mobile Gamer: Get the Realme GT Master. The performance and display are essential.

My Choice

If I were choosing between these two, I'd absolutely go for the Realme GT Master. The difference in performance is just too significant to ignore. The AMOLED display is a major plus, and that 65W charging is addictive. While the Redmi 12 has a bigger battery, the GT Master's ability to charge so quickly mitigates that concern for me. For the types of tasks I do daily, the GT Master would provide a much smoother and more enjoyable experience.
