Final Thoughts

My Choice:

If I had to choose, I'd pick the Xiaomi 12. I value the higher performance for day-to-day tasks and love the flexibility of wireless charging. It's not just about the spec sheet though, it's about the experience. I also value build quality, and with the Corning Gorilla Glass Victus, the Xiaomi 12 offers superior protection. The 120Hz display and advanced camera features are also a big plus for me. While the Oppo Reno8 is a great phone, the Xiaomi 12 has an edge. It's a phone that excites me because of its power, and I find the fast charging of the Oppo Reno8 to be less important to me, especially since I can utilize the Xiaomi 12 wireless charging and charge it overnight. The camera is a very minor difference, and I wouldn't base my buying decision on that.

Ultimately, the best phone for you depends on what you value most. Consider how you'll use the phone daily, and let that guide your decision.
