  • Scenario 3: Budget-Conscious Buyer: If your main goal is saving money, the Poco M3 may be a good choice but bear in mind the Redmi Note 12S provides a better experience at a reasonable price.
  • Scenario 4: Everyday Use and Photography: For most users, the Redmi Note 12S is the better option because it is much more well rounded with a much better display, camera and performance.

Personal Choice

If I were choosing between these two phones, I would pick the Xiaomi Redmi Note 12S. While the Poco M3's battery life is tempting, the Redmi Note 12S's improvements in display technology, processing power, camera versatility, and charging speed are too significant to ignore. The faster 90Hz AMOLED display alone makes a huge difference in daily use, and the enhanced camera capabilities make the device more versatile. The increase in RAM also provides a smoother experience, and faster charging speed is a big plus. The lack of expendable storage on both devices is unfortunate, but the 256GB option on the Redmi Note 12S compensates. While there may be some situations where the Poco M3's battery life and GPS may be preferrable, the advantages offered by the Redmi Note 12S provide a much better everyday experience.
