My Personal Choice

If I were choosing between these two, I would definitely pick the Xiaomi Redmi Note 11. Here’s why:

  • Display Quality: As a tech journalist, I’m always looking at screens. The AMOLED display with higher resolution and brightness is a game-changer for me. The sharper image and vibrant colors make a noticeable difference in day-to-day use.
  • Performance: The Snapdragon 680 is noticeably more powerful, which is important for daily responsiveness and handling the occasional game. The overall experience is just smoother and faster.
  • Camera Versatility: I enjoy taking photos in all sorts of scenarios, and the wider selection of lenses on the Redmi Note 11 gives me much more to play with. The quality is superior as well.

While the Realme C51 has a newer software and a larger screen, those alone aren’t compelling enough for me when the overall experience would be inferior. For my needs, the Xiaomi Redmi Note 11 offers a much better and more rounded experience. Ultimately, it comes down to personal priorities, but for my needs and preferences, the Redmi Note 11 is the clear winner.
