    • If longer battery life is the main concern, Realme 12+ is better.
  2. How important is camera versatility and high-resolution video to me?

    • If you need versatility, optical zoom, and high video quality, the OnePlus 9 Pro is the better choice.

What I Would Choose and Why:

If I were choosing between these two phones, I would personally go with the Realme 12+. While the OnePlus 9 Pro has its advantages in terms of processing power and camera features, the Realme 12+ appeals to me due to its newer software, significantly better battery life and outdoor visibility, excellent display technology, and macro lens - all at a lower price point. The performance of the Realme 12+ is sufficient for my daily needs and the improved battery and outdoor visibility features will come in handy in my day-to-day life. While the OnePlus 9 Pro is the more powerful phone, for most daily use cases the features of the Realme 12+ outweigh the extra processing power of the OnePlus 9 Pro. The price point makes it an even better value proposition, especially when considering that the OnePlus 9 Pro is several years old. I consider the performance of the Realme 12+ more than adequate, especially for a daily driver that is not used for gaming. The main selling points for me on the Realme 12+ are the more up-to-date operating system, better battery life and outdoor visibility, and its lower price.
