    • If yes, the iPhone 15 Plus is your go-to. Its A16 Bionic chip delivers a substantial performance advantage.
    • If no the Xiaomi 12X will be more than enough.
  2. Is a smooth display and rapid charging your top priority?
    • If yes, the Xiaomi 12X’s 120Hz refresh rate and 67W charging are a better fit.
    • If no the iPhone's more accurate color representation and 2000 nits of brightness are great alternatives.
  3. Do you need a variety of camera lenses or wireless charging, is software an important part of your selection?
    • If yes, the Xiaomi 12X has three dedicated lenses and the iPhone 15 Plus wireless charging, but they lack the others' strength.
    • If no, your choice is mostly about the ecosystem you prefer.

Scenario-Based Recommendations:

  • The Multimedia Enthusiast: For someone who watches lots of movies and videos, the iPhone 15 Plus's display will give a better experience, while the Xiaomi 12X offers good audio quality.

My Pick

If I were choosing between these two devices, I'd lean towards the Apple iPhone 15 Plus. Here's why:

While the Xiaomi 12X is a fantastic phone, its older chipset, the lack of wireless charging, its worse low-light picture capabilities and less appealing software updates make it a harder choice. The iPhone 15 Plus's A16 Bionic chip provides a substantial performance advantage, coupled with the outstanding screen and camera quality, that will translate into a more enjoyable experience day to day. Despite the slower charging speeds, I'd be willing to compromise for that performance and screen quality. Moreover, Apple's commitment to software updates and support means the phone will remain relevant and perform optimally for a longer period, making it a better long-term investment for me, despite its higher price tag.

That's the breakdown. Let me know if you have any more questions.
