4. Decision Framework

Here are three key questions to help buyers decide:

  1. What is your budget? The OnePlus 9 Pro is a premium phone that comes at a premium price, while the Realme C65 is aimed at budget-conscious buyers.
  2. How important is performance? If you need the best possible performance for demanding games and apps, the OnePlus 9 Pro is the better choice. If you mostly do light tasks, the Realme C65 may be sufficient.

  • Scenario 3: If you're a mobile gamer, the OnePlus 9 Pro provides better performance, a smoother display and a more advanced sensor suite than the Realme C65.

My Choice

If I were choosing between these two phones, I would pick the OnePlus 9 Pro.

Here's why: While the Realme C65 is a more modern phone in the sense that it has newer software, and it's a strong budget contender, the OnePlus 9 Pro offers a vastly superior experience in most areas that matter to me. The display is significantly better, which is crucial for enjoying media and for comfort during long use periods. The camera capabilities on the OnePlus are much more advanced and I often use my phone for photography, so I appreciate features such as OIS, a dedicated telephoto and wide angle lenses, and the ability to shoot in 8K video. Additionally, the OnePlus provides a performance boost for demanding apps and games, and having extra features such as wireless charging is always a plus.

The price difference is likely considerable, and the OnePlus 9 Pro is an older phone, but given its superior specifications, the extra cost is something I would be willing to pay. While the Realme C65 has a bigger battery, the OnePlus 9 Pro's fast charging makes up for this. I value a high-quality display, strong performance, advanced camera system, and the convenience of wireless charging. The OnePlus 9 Pro excels in these aspects, and ultimately it would fit my use case much better, despite the Realme C65's advantages in price, battery and newer software.
