4. Buying Decision Framework

Ask yourself:

  1. Do I prioritize display quality or battery life? (AMOLED vs. IPS LCD & bigger battery)
  2. Do I need faster charging or a smoother refresh rate? (30W vs. 120Hz)
  3. Am I more into photography or raw performance? (Better cameras vs. faster chipset & RAM)

Scenario-Based Recommendations:

  • For a student who watches videos & takes notes: OnePlus Nord CE 5G (sharper screen, lighter).
  • For a gamer or heavy multitasker: Realme 12x (120Hz, 12GB RAM).
  • For a social media user & content creator: OnePlus Nord CE 5G (better cameras, 4K video).

Final Verdict: What I’d Choose

I’d pick the OnePlus Nord CE 5G—even though it’s older, the AMOLED display, better cameras, and fast charging make it a better all-rounder for media, photography, and day-to-day use. The Realme 12x wins in battery and raw performance, but the Nord CE 5G offers a more premium user experience for most people.

However, if you need more RAM, a bigger battery, and a larger screen, the Realme 12x is the better pick. It depends on what matters most to you!
