My Choice

If I were choosing between these two phones, I would pick the Xiaomi Redmi Note 13 Pro+. While the OnePlus 9 has some compelling features such as the better GPS, wireless charging, a wide-angle lens, and slightly better performance, the overall package of the Redmi Note 13 Pro+ is simply more appealing. The superior display, significantly better battery life with faster charging, superior main camera with OIS, and the more up-to-date software make it a much more practical and future-proof phone for my needs. As someone who values a great display, long battery life, and a versatile camera system, the Xiaomi Redmi Note 13 Pro+ edges out the OnePlus 9. The minor trade-offs (no wireless charging and lower 8K recording, slightly lower performance) are acceptable given the considerable advantages in other areas.
