Realme 12x vs Vivo T3x vs Samsung Galaxy M15: Verdict

The Vivo T3x could be a good choice for a performance-centric smartphone with a big battery and fast charging in the budget segment. However, keep in mind that the smartphone does not offer an ultra-wide-angle camera and a versatile camera setup is what you’re looking for, the Samsung Galaxy M15 is a better choice.

Also, the Samsung Galaxy M15 offers an sAMOLED display and will get updates up to Android 18, which we don’t see in this segment. However, the smartphone has a single speaker, so if multimedia consumption is a priority, the Galaxy M15 may not be a good choice.

The Realme 12x 5G offers a stereo speaker setup and is cheaper than Vivo and Samsung’s offerings. It also supports 45W fast charging, which is rare in this segment. If you’re tight on budget and looking for a smartphone with a good design, the Realme 12x 5G won’t disappoint.
