My Choice

While the Xiaomi Redmi Note 12 4G is a more modern phone with a longer battery and an AMOLED screen, the raw performance and camera quality of the OnePlus 9 Pro is too significant to ignore. The Snapdragon 888 chipset, coupled with a higher quality display and more powerful camera suite make the OnePlus 9 Pro a much better choice for anything besides basic everyday usage. The faster charging speeds and additional features like wireless charging and stereo speakers also justify the higher price point in my eyes. Although the Xiaomi Redmi Note 12 4G is more than adequate for basic usage, the OnePlus 9 Pro has the upper hand in most other categories.
