4. Buying Decision Framework

Ask Yourself These Three Questions:

  2. Do you prefer a large display and longer battery, or a smaller, more portable design?
  3. How much do you prioritize high-end video features and build quality?

Scenario-Based Recommendations:

  • For the Power User/Gamer: If you are always on your phone, playing games, or watching videos, go for the Realme GT Neo2, the extra battery life and screen size will benefit you.
  • For the Photographer/Content Creator: If you prioritize camera quality, especially video, and need a smaller, easier-to-handle phone, the Xiaomi 12X is a better pick.
  • For the Average User: The Xiaomi 12X is a great all-rounder for everyday tasks while offering an improved camera system and slightly better build quality.

Personal Choice

If I were choosing between these two, I'd lean towards the Xiaomi 12X. While the Realme GT Neo2 has its advantages—especially the larger screen and battery—the 12X's more premium build, compact size, superior video capabilities, and potentially better main camera would better suit my needs. I tend to prioritize a high-quality camera setup and build quality over a larger screen, so the trade-off in battery life is something I'm willing to accept. The 12X offers that extra edge in video quality and overall feel that I value in a daily driver. I feel confident that its camera system is slightly more refined than that of the GT Neo2.
