4. Buying Decision Framework

Here are three key questions to help you decide:

  1. How important is display quality? If you value a vibrant, sharp display, the Redmi Note 11S is the clear winner. If you just need a large screen, the Realme C51 is sufficient.
  2. Do you need more performance or storage? The Redmi Note 11S offers better overall performance, while the Realme C51 offers more maximum storage.

Personal Choice

If I had to choose between these two phones, I'd go with the Xiaomi Redmi Note 11S.

Why? As someone who values display quality, performance, and camera capabilities, the Redmi Note 11S simply offers a more well-rounded experience. The AMOLED display alone is a game-changer, and the faster chipset and better camera system makes it a no-brainer for me. While the Realme C51 has its merits, the Redmi Note 11S clearly offers the better experience in the areas I prioritize most. The older software and lack of expandable storage aren't deal breakers for me. The trade-off of a little less software functionality for a premium experience is worth it in my opinion.
