- How do you use your camera? If you rely on the zoom capabilities the S21 FE's telephoto lens might be what you need, and the selfie camera may be preferred as well. If you want a great general-purpose camera with more detail in good lighting, and the ability to take wide angle and macro shots the OnePlus 12R is a better choice.
- How much do you care about battery life and charging speed? The 12R has a significantly bigger battery, much faster charging and that should be considered if you want your phone to last all day with heavy usage. If your use is more casual, or if you have a wireless charger you want to use, then the S21 FE can be a better fit.

What I Would Choose and Why
Personally, I would choose the OnePlus 12R. Here's why:
As a tech journalist and someone who uses their phone heavily for both work and play, performance is paramount. The Snapdragon 8 Gen 2 chipset in the 12R is a game-changer, offering significantly better performance in almost all aspects. The much brighter display is also a big win for me, especially in outdoor settings, and the large battery with 100W charging gives me all-day power, and I get back up and running very fast when it is low.
While the S21 FE has its merits, such as a more compact design and a dedicated telephoto camera, the 12R's overall power, screen, and battery life advantages are too significant for my use cases. The OnePlus 12R provides a more future-proof device that can handle all the demanding tasks I throw at it, and it will last all day.
Ultimately, the best choice depends on individual needs and preferences, but for my workflow and usage patterns, the OnePlus 12R offers the best all-around experience.
