4. Decision Framework

Key Questions for Buyers:

  1. Screen Visibility: Do you primarily use your phone indoors or outdoors in bright light? (Poco F4 is much better for bright outdoor conditions)
  2. Camera Priorities: Do you prioritize ultra-wide and macro lens quality, or are selfies and the main camera more important? (OnePlus 9R wins in ultra-wide, Poco F4 wins in main camera)
  3. Software and Battery: Do you want a newer OS and faster charging or are you ok with slightly older software and charging speeds? (Poco F4 wins in both)

Scenario-Based Recommendations:

  • Outdoor Enthusiast: Choose the Xiaomi Poco F4 for its brighter screen.
  • Casual Photographer: Choose the OnePlus 9R for its better ultra-wide camera and dedicated depth sensor.
  • Gaming Enthusiast: Choose the Xiaomi Poco F4 for its slightly better benchmark performance and faster charging.
  • Daily User: If the price is similar, Poco F4's faster charging and brighter screen are generally more useful.

My Choice

If I had to choose, I would pick the Xiaomi Poco F4. While I appreciate the OnePlus 9R's strengths in the ultra-wide camera and its compact size, the Poco F4's superior screen brightness, faster charging, newer Android version and better protection make it a more compelling daily driver for me. The improved outdoor visibility is a significant advantage, and the slightly better performance and faster charging are useful benefits for everyday use. Moreover, for the type of photography I do, the main camera resolution is important and the Poco F4 has a better main camera, the selfie camera is also a priority and the Poco F4 excels at that too. The added advantage of better security with a side-mounted fingerprint sensor, along with hi-res audio support, rounds out the package as a better fit for my use case.
