Realme 9 Pro+: Users who prioritize fast charging, a potentially better main camera, and a newer operating system out of the box. Suitable for general users, social media enthusiasts, and those who value quick charging.

4. Decision Framework

  • What is your budget? The OnePlus 8 might be slightly more expensive due to its flagship-level specs.
  • What are your performance needs? For demanding tasks and gaming, the OnePlus 8 is the clear winner.
  • How important is fast charging? If minimizing charging time is crucial, the Realme 9 Pro+ is the better choice.

My Choice: OnePlus 8

Despite being older, the OnePlus 8's superior performance due to the Snapdragon 865 is the deciding factor for me. Performance significantly impacts the long-term usability of a phone, ensuring smooth operation even as apps become more demanding. The significantly brighter display, crucial for outdoor use, further solidifies my choice. While the Realme 9 Pro+ offers advantages in charging speed and potentially camera quality, these do not outweigh the performance gap and the confirmed brighter display of the OnePlus 8 for my usage. I often use my phone for demanding tasks and value a smooth, lag-free experience above all else. The significantly brighter screen is essential for comfortable outdoor use. The missing brightness data for the Realme is a significant concern.
