4. Buying Decision Framework

3 Questions to Ask Yourself:

  1. Do you care more about performance or battery life? (Reno6 = speed, Poco C65 = endurance)
  2. Is display quality important for you? (Reno6’s AMOLED wins.)
  3. Do you take a lot of photos/videos? (Reno6 has far better cameras.)

Scenario-Based Recommendations:

  • Best for gaming & speed?Reno6 5G (way faster chipset).
  • Best for battery life?Poco C65 (5000mAh + efficient chip).
  • Best all-rounder?Reno6 5G (better display, cameras, charging).

Final Verdict: Which Would I Choose?

Winner: Oppo Reno6 5G 🏆

Why?

  • The display, performance, and camera differences are too big to ignore.
  • 65W charging is a game-changer—no more waiting hours for a full charge.
  • Even though the Poco C65 has a bigger battery, the Reno6’s efficiency (6nm chip) helps mitigate the difference.

Exception: If you only care about battery life and don’t need speed/cameras, the Poco C65 makes sense. But for most users, the Reno6 is the better phone.
