4. Buying Decision Framework

Here are three questions to help you decide:

  1. Do you prioritize display quality and performance, or battery life and latest software? If display and performance are crucial, the Xiaomi 12X is the clear choice. If you want longer battery life and newer software, the Realme 12x is better for you.
  2. What is your typical use case? If you're a gamer or heavy app user, the Xiaomi 12X's extra power is necessary. For basic use, the Realme 12x will be fine.
  3. How much do you value fast charging and camera quality? If you hate waiting for your phone to charge and prefer better quality photos and videos the Xiaomi 12X should be your preferred choice.

Scenario-Based Recommendations:

  • Scenario 1: Gaming on the go. The Xiaomi 12X, with its Snapdragon 870 and Adreno 650 GPU, is a great choice.
  • Scenario 2: All-day use without charging. The Realme 12x is the better pick due to it's 5000mAh battery.
  • Scenario 3: A balance of features without breaking the bank. The Realme 12x provides a good balance of features for the cost with the latest software, the Xiaomi 12X is still the better all rounder though.
  • Scenario 4: Top notch display for media consumption. The Xiaomi 12X is clearly better with its brighter, sharper AMOLED display with better pixel density and resolution.

My Choice

Personally, I would choose the Xiaomi 12X. While the Realme 12x has a bigger battery and more recent software, the significantly better display, superior performance, and higher-quality camera system on the Xiaomi 12X make it the more compelling choice for me. As someone who values a great visual experience, responsiveness, and versatile photography, the Xiaomi 12X provides an all round better user experience overall.

The faster charging is also a game-changer, reducing the pain of low battery, and the additional audio enhancements (Dolby Atmos) and advanced WiFi and GPS support just tips the scales further in favor of the Xiaomi 12x. While I appreciate the latest software and larger battery on the Realme 12x, the improvements on the Xiaomi 12X on the aspects I value the most, makes it my preferred choice.
