  • realme 8: Unknown battery size, unknown camera specs, unknown connectivity, unknown charging, unknown screen protection.
  • Incomplete Data: The realme 8 specs provided are extremely incomplete making it difficult to compare fairly.

3. User Profiles and Recommendations

Xiaomi 12X is ideal for:

  • Users who value a compact phone: Its size and weight make it comfortable for single-handed use and carrying in the pocket.
  • Photography enthusiasts: The diverse camera setup offers high quality photos and video.
  • Performance-focused users: It’s well-suited for demanding apps and gaming, offering the most complete feature set in the comparison.
  • Users needing fast charging: The fast charging greatly reduces the downtime.

realme 8 is potentially suitable for:

  • Users who prioritize a large display: The larger display is better for media consumption.
  • Users who want the newest software: Android 14 offers better software features and security.

4. Buying Decision Framework

Here are three questions to consider before making a decision:

  1. Do I prioritize a compact, feature rich phone, or a larger screen? The Xiaomi 12X is significantly more compact and feature rich, while the realme 8 focuses on screen size.
  2. Do I need a robust and versatile camera system? If photography is important, the Xiaomi 12X is the better choice given its feature set.
  3. How important are the software features? If the newest OS is essential, the realme 8 is preferred. If the software features are less critical, the Xiaomi 12X is the better pick.

Scenario-Based Recommendations:

  • For the Casual User: If you primarily browse social media, watch videos, and do light tasks, the realme 8 is potentially more suited for you given its larger display and new Android OS. However, given the missing data on the camera, battery, and other specs, it is hard to recommend this device over the Xiaomi 12X.
  • For the Mobile Photographer/Creator: The Xiaomi 12X, with its excellent camera system and video recording capabilities, is the clear winner.
  • For the Power User: The Xiaomi 12X is the clear winner given its performance, RAM, and connectivity.

My Choice

Given the information provided, I would choose the Xiaomi 12X. Here’s why:

The realme 8's biggest asset is its larger screen and newer OS, however, the lack of any other supporting data is a massive red flag. The Xiaomi 12X, on the other hand, provides a comprehensive package. It has a premium build, a great display, robust performance, a fantastic camera system, and a fast charging battery with a complete feature set. Its compact size is a major advantage for me as well, as I prefer phones that are easy to handle.

While the Xiaomi 12X is running an older version of Android, this can easily be updated to a newer version. The trade off for this is having a complete feature set and a more robust device. The lack of data on the realme 8's features makes this an easy choice. I am not willing to recommend a product that has so much missing data.
