My Choice

If I were choosing between these two phones for my personal use, I would absolutely choose the Xiaomi Redmi Note 12 Pro+. Here's why:

As a tech journalist, I spend a lot of time on my phone, both for work and leisure. I value a smooth, fast user experience, a crisp and vibrant display, and a capable camera. The Redmi delivers on all these fronts:

  1. Performance: The difference in processing power is night and day. The Redmi's Dimensity 1080 chip and the vast amount of RAM will handle anything I throw at it, from demanding games to heavy multitasking.
  2. Display: The OLED display with a 120Hz refresh rate would make using the phone enjoyable, especially when I’m watching videos or scrolling through articles for research.
  3. Camera: I often find myself capturing photos and videos for work, and the Redmi's 200MP camera would allow me to document my experiences with confidence. The wide-angle lens is a big plus, too.
  4. Fast Charging: I can't overstate how convenient 120W fast charging is. It would mean less time tethered to a charger and more time using the phone.
  5. Audio: For reviewing music related gear, high fidelity audio is a must have, and this is something that the Redmi excels at with its stereo speakers and Dolby Atmos capabilities.

While I appreciate that the Samsung Galaxy A03s has its place for users on a tight budget, the Xiaomi Redmi Note 12 Pro+ is a significantly better investment for those who want an all-around excellent smartphone experience. The value that the Xiaomi brings to the table is simply phenomenal.

Ultimately, the right choice depends on your specific needs and priorities, but for me, the Redmi checks all the boxes, and offers an experience that justifies its higher price tag compared to the A03s.
