My Choice and Why

If I were choosing between these two phones, I would choose the Apple iPhone 15 Plus. While the Xiaomi Poco M3 has an appealing larger battery, the overall user experience offered by the iPhone 15 Plus is far superior.

Here’s my reasoning:

  1. Performance and Future-Proofing: The Apple A16 Bionic chip is significantly more powerful, which means smoother multitasking, faster app loading, and a much better overall user experience, and will also be usable for longer as the phone will handle future software updates much better.

  5. Long-Term Value: While the iPhone 15 Plus is more expensive upfront, it tends to retain its value better than budget smartphones.
  6. Better Audio Recording: The Noise cancelling mics and 3 microphones will come in handy for all kinds of usage.

Even though the Poco M3 has the advantage in battery and affordability, the massive upgrade in performance, display quality, and camera quality with the iPhone 15 Plus makes it the better overall choice for me. The higher initial cost is a worthwhile investment, as the phone is likely to provide a better long-term user experience due to better quality and software support.
