My Choice

Given the information, I would choose the OnePlus 12.

Reasoning:

While the Xiaomi Poco M3 has the advantage of a slightly larger battery, this advantage is easily outweighed by the massive superiority of the OnePlus 12 in virtually every other aspect that matters to me.

Here's why I'd pick the OnePlus 12:

  • Display Quality: The vibrant AMOLED screen with a 120Hz refresh rate and much higher brightness of the OnePlus 12 significantly enhances the user experience, making everyday interactions more enjoyable.
  • Performance: The Snapdragon 8 Gen 3 chipset provides unmatched performance. Having used mid-range phones, the performance boost is essential for smooth multitasking, gaming, and demanding applications.
  • Camera Capabilities: As someone who values mobile photography and videography, the versatile camera system with better sensors, telephoto, wide angle and 8K video support is far superior to the basic camera found in Poco M3.
  • Future-Proofing: The OnePlus 12’s newer operating system (Android 14) and better hardware make it a more future-proof device than the Poco M3, whose dated Android 10 will quickly stop being supported.
  • Overall User Experience: The combination of a high-quality display, fast performance, and a more advanced camera system provide a significantly better overall user experience.

While the Poco M3 might have a marginal advantage in battery life, the significantly superior technology of the OnePlus 12 in key areas makes the trade-off worthwhile. I need a phone that can handle all tasks smoothly, take great pictures, and remain relevant for years to come. The OnePlus 12 does exactly that. While the price is higher, it justifies the cost for my priorities.
