4. Buying Decision Framework

Here are three questions to help you decide:

  1. What is your budget? The price difference will be the biggest factor.
  2. What will you mostly use your phone for? If you need performance, you’ll want the Xiaomi 12; if you need basic functionality, the Nokia C21 Plus will be fine.
  3. How important are camera quality and display quality? If you want the best picture, the Xiaomi 12 is a must. If you just need something that works, the C21 Plus will do.

Scenario-Based Recommendations:

  • "I need a phone for gaming and watching videos." Go with the Xiaomi 12 for its superior performance and display quality.
  • "I need a basic phone for calls, texts, and occasional browsing, and I'm on a budget." The Nokia C21 Plus will cover those needs without breaking the bank.
  • "I take a lot of photos and videos, often on the go." The Xiaomi 12, with its high-quality cameras, is your best bet.

My Choice

If I were to choose between these two devices for my everyday use, I would definitely choose the Xiaomi 12.

Here's why:

As someone who values performance, display quality, and camera capabilities, the Xiaomi 12 is simply the superior option. The Snapdragon 8 Gen 1 chip ensures that I can run any application or game smoothly, and the 120Hz AMOLED display makes every interaction feel seamless and visually stunning. The versatile camera system means I can capture high quality photos and videos in any situation. While it comes with a higher price tag, the overall package, with its performance, build quality, and features, makes it the better investment for my needs. The Nokia C21 Plus serves its purpose well for those on a budget, but as a tech journalist I require a device with a more robust set of capabilities.

Ultimately, the "best" phone always depends on the user's unique needs and preferences, but in this case, the Xiaomi 12 edges out the Nokia C21 Plus for my purposes.
