4. Buying Decision Framework

Here are three questions to help you decide:

  1. "What’s more important: screen fluidity or outdoor readability?" If you prioritize a super smooth experience, the Xiaomi 12 is your go-to. If you want clarity under the sun, you need the iPhone 15.

  2. "How often do I find myself low on battery?" If you are consistently low on battery or you’re always on the go, the faster charging on the Xiaomi is ideal. If you have a consistent charging routine or don't require rapid top-ups, the iPhone is fine.

  3. "What do I need the camera for?" If you prioritize a dedicated macro camera and 8K video, then the Xiaomi is better. If you prioritize the best overall quality and low-light performance with a wider array of features, choose the iPhone 15.

Scenario-Based Recommendations:

  • The Tech Enthusiast: If you love playing with the latest features and enjoy tinkering, the Xiaomi offers more versatile options with faster charging.
  • The Casual User: If you just want a solid camera, great performance, and an excellent user experience, the iPhone 15 offers a complete and polished solution.
  • The Photographer: The iPhone 15 has a better camera performance in terms of dynamic range, low-light capabilities, and video features.
  • The Mobile Gamer: The Xiaomi 12, with its 120 Hz display and more RAM is a better choice.

My Choice

If I had to choose, I would personally lean towards the Apple iPhone 15. While the Xiaomi 12 has some compelling advantages like the smoother screen, faster charging, and versatility, the A16 Bionic chip's performance boost, the superior screen brightness, and the more refined camera capabilities are simply more important for my day-to-day workflow. I also appreciate the long-term software support Apple provides and I am already invested in their ecosystem. The consistency and reliability that come with the iOS experience are also a big draw for me, so the iPhone 15 edges out the Xiaomi 12.

But that's just me - your priorities might be different! Hope this helps clarify things and helps you make the right choice.
