Personal Choice
If I were choosing between these two phones, I would choose the Xiaomi Mi 11. While the Oppo A57 4G has a slightly larger battery and comes with a newer Android version out-of-the-box, the Xiaomi Mi 11 excels in virtually every other aspect. The significantly superior display, much faster performance, dramatically better cameras, faster charging, and premium build quality make it the clear choice for a user that values a top-tier smartphone experience. Even though it would cost significantly more, the user experience difference is so significant, that it is a worthwhile trade-off. For my usage, which includes a lot of media consumption, gaming, and photography, the Mi 11 provides all of those requirements at a very high level. The Oppo A57 4G simply does not compare in any area I value in a smartphone, making the cost saving not worthwhile.
