  3. What kind of photography do you prioritize? (Wide angle, macro, or video)

Scenario-Based Recommendations:

  • Scenario 1: The Performance Seeker:
    • Recommendation: OnePlus 9. If top performance is a must, the Snapdragon 888 is the clear choice.

    • Recommendation: OnePlus 9. The much brighter screen and superior wide-angle lens provide more practical benefits.
  • Scenario 4: The Macro Photographer:
    • Recommendation: Xiaomi 11 Lite 5G NE. For macro photography, the 5MP macro lens on the Xiaomi is the only option.

Personal Recommendation

If I had to choose between the OnePlus 9 and the Xiaomi 11 Lite 5G NE, I would personally choose the OnePlus 9. While the Xiaomi offers a more comfortable and portable form factor, the significantly better performance of the Snapdragon 888, combined with the much brighter display, far outweighs the benefits of the macro lens and lighter weight that the Xiaomi offers.

The OnePlus 9's vastly superior primary camera sensor and wide-angle lens would provide better image quality in most scenarios, which is more important to me than a macro lens. I value the fast charging and wireless charging which I think are quality of life improvements. Furthermore, as someone who often uses my phone outdoors, the much higher brightness would make a significant difference. While the side mounted fingerprint sensor of the Xiaomi is great, it is not a deciding factor, and the additional OS update is very welcome.

The slightly larger weight and size of the OnePlus 9 are a trade-off I'm willing to make, in exchange for the performance gains, more convenient charging, and overall better quality primary and wide angle camera capabilities. Therefore the OnePlus 9 would be my choice.
