  3. Battery Life: Is battery life the top priority, or is fast charging acceptable?

Scenario-Based Recommendations:

  • Scenario 1: Performance is Paramount: If you need the best performance for demanding tasks and gaming, the OnePlus 9R is the clear choice.
  • Scenario 2: Battery Life is Crucial: If battery life is your top priority and you are not a heavy gamer, the Xiaomi Poco M4 Pro 5G is better suited.
  • Scenario 3: Balanced Needs with a Higher Quality Screen: If you want solid performance with a better screen and better camera, the OnePlus 9R is the better choice.
  • Scenario 4: You're on a Tight Budget: If you are on a budget, you may be better suited to purchase the Xiaomi Poco M4 Pro 5G.

Personal Choice

If I were choosing between these two phones, I would choose the OnePlus 9R. My primary reason for this would be the display. The AMOLED panel with 120Hz is significantly better and it would greatly enhance the visual experience. Secondly, the performance increase offered by the Snapdragon 870 is something that I would find beneficial. While the battery is smaller, the 65W fast charging more than compensates for this, as charging speeds are also very important to me, and I usually have access to a charger.
