My Choice

If I were to choose between these two phones, I would personally go for the OnePlus 12R. Here's why:

As a tech journalist and analyst, I prioritize performance and battery life, especially when I need to test multiple applications and stay connected throughout the day. While the Xiaomi 12 is compelling with its more compact design and wireless charging capabilities, the OnePlus 12R's newer chipset, bigger battery, faster charging, and brighter screen align better with my needs. The significant performance boost, as indicated by the AnTuTu scores, makes the OnePlus 12R the superior choice for my workflow. I also tend to watch a lot of videos, so a bigger, brighter screen is a big plus for me. It might be slightly heavier, but the trade-off is well worth it for the performance and battery gains, in my view. Plus, the newer Android version guarantees I'll get more software upgrades down the road. I'm also curious to test out its Wi-Fi 7 capabilities.

Ultimately, the best phone depends on your personal needs, but for me, the OnePlus 12R is the more compelling option.
