  2. How important is battery life? If maximizing battery life is the top priority, the Poco M3 has a clear advantage.
  3. How important is performance? If you plan to game or use demanding apps, the Poco X3 GT's significantly higher performance is crucial.

Scenario-Based Recommendations:

  • Scenario 1 (Casual User): If you mostly browse the internet, use social media, and make calls, the Poco M3 is a very capable option that will save you money. However, if budget allows, the X3 GT will provide a superior experience.
  • Scenario 2 (Gaming/Power User): If you plan on playing graphics-intensive games and using demanding apps, the Poco X3 GT is the clear choice.
  • Scenario 3 (Content Creator): If you want a better camera with more features, along with 4k video recording capabilities, the X3 GT is the way to go.
  • Scenario 4 (Budget-Focused Traveler): If you need a phone that can last a long time without charging, and the extra performance isn't a big deal, the Poco M3 is ideal.

My Choice

If I were choosing between these two phones, I would choose the Xiaomi Poco X3 GT. While the Poco M3 has a larger battery, the massive performance upgrade offered by the X3 GT's Dimensity 1100 chipset and the 120Hz display make it a significantly better phone in terms of overall user experience. The 67W fast charging is a game-changer. I would be much happier with the more responsive experience, better camera capabilities and higher quality screen, than with slightly longer battery life. Although battery is important, the X3 GT battery should easily get through most days. The X3 GT's better connectivity (Wi-Fi 6 and Bluetooth 5.2) also make it a more future-proof option. The slightly larger screen and higher resolution camera are nice-to-haves. Therefore, the X3 GT is the superior phone and worth the extra cost.
