My Choice
If I had to choose between these two devices, I would definitely go with the Xiaomi 12. While the larger battery on the Oppo A57 4G is appealing, the Xiaomi 12's advantages in virtually every other area—display, performance, camera, charging, audio and connectivity—are just too significant to ignore. It offers a far more enjoyable and powerful user experience, making it a worthwhile investment. It's simply the superior device for all but the most budget-conscious users. The differences in performance alone justify the price gap. I’d take a slightly smaller battery and faster charging over the A57’s longer battery life any day.
