  • Scenario 3: Balance of Features: If you are somewhere in between, where you want some performance and good camera, but are still a bit price conscious, then look into options at intermediate price points which are not covered in this comparison.

My Choice

If I had to choose between these two, I would personally pick the Apple iPhone 13. While the Redmi A3x has the benefit of a larger battery and a lower price point, the overall experience of the iPhone 13 is significantly superior, mainly due to these factors:

  • Performance: As someone who likes to use my phone for more than just basic tasks, the vastly superior performance of the A15 Bionic chip is essential for my workflow and gaming needs.
  • Display: The OLED screen with its clarity, vibrant colors and high brightness will improve my media consumption, and general usage of the device.
  • Camera: I value a good camera for capturing moments and the significantly better camera system on the iPhone is something I do value.
  • Software: I am very much invested into the Apple ecosystem, and the continued support, optimization, and privacy is very beneficial to me.

Although the iPhone is much more expensive, the overall user experience and long-term value justify the cost. I look for devices that offer the best experience and features, even if they are not the cheapest on the market. It is a worthwhile upgrade.
