  • Scenario 3 (Audio Quality): If you prioritize excellent speaker quality, the Redmi Note 9T is the better option as it comes with stereo speakers.

My Choice

If I were choosing between these two phones, I would pick the Samsung Galaxy M55. Here's why:

Priorities:

  • Performance: As a regular user who uses my phone for multiple applications, a lot of browsing, and occasional gaming, the Snapdragon 7 Gen 1 offers a much more enjoyable and lag-free experience than the Dimensity 800U. The higher AnTuTu score is a good indicator of real-world performance.

  • Display: The AMOLED display with a 120Hz refresh rate is a huge upgrade over the IPS LCD. The richer colors and smoother animations improve daily usage significantly, making it ideal for watching videos and browsing.

  • Camera Quality: I value the ability to capture high-quality photos and videos with decent stability. The M55's OIS and higher-resolution sensors provide a better and more flexible experience in various scenarios.

Trade-offs:

  • I'm willing to purchase a separate charger to get the faster 45W charging speed, which is a major convenience for me.
  • I can live without the stereo speakers and side mounted fingerprint sensor in favor of a superior display, performance and camera.

Conclusion:

The Samsung Galaxy M55 offers a better overall package that aligns with my priorities. While the Redmi Note 9T is a capable phone with stereo speakers, the improvements in the M55 in terms of performance, display, and camera make it worth the higher cost to me.
