- How important is performance and display quality to me? If you value smooth performance, sharp visuals, and vibrant colors, the OnePlus 8T is the clear choice.
- How important is battery life? If battery life is a top priority, the Realme C51 might offer slightly better endurance, but this comes at the cost of significant performance and feature downgrades.
Scenario-Based Recommendations:
- Scenario 1: Budget is extremely tight. The Realme C51 is the only viable option.
- Scenario 2: Performance and display are important, and budget allows. The OnePlus 8T is the far superior choice.
- Scenario 3: Battery life is the absolute top priority, and performance is secondary. The Realme C51 might be preferred.
My Choice
I would choose the OnePlus 8T. While it's an older phone, the vastly superior performance offered by the Snapdragon 865, coupled with the excellent AMOLED display and better camera system, outweigh the advantages of the Realme C51 (newer Android version and potentially slightly better battery life). The Realme C51 is simply too underpowered for my typical usage, which includes multitasking, gaming, and photography. The better display on the OnePlus 8T is also a significant factor, as I consume a lot of media on my phone. The trade-off in battery life is acceptable, especially considering the OnePlus 8T's significantly faster charging capabilities.
