  • Scenario 3: Balanced User: If you want a balance of battery life and performance and the budget is not very tight, the OnePlus Nord 2 5G is a better choice despite having slightly smaller battery because of the significantly better processing power. The higher battery of the Xiaomi Poco M3 is better only when the use case for the phone includes very basic usage.

Final Decision

I would choose the OnePlus Nord 2 5G.

While the Xiaomi Poco M3 has a larger battery and is more budget-friendly, the Nord 2 5G offers a significantly better overall user experience. The superior AMOLED display, the vastly more powerful processor, the much better camera, and the fast charging capabilities make a huge difference in daily usage. The Nord 2 will be a much better device for gaming, taking photos, video calls, and general usage.

The Poco M3, though capable, is best used as a budget device while the Nord 2 is a more practical, daily driver.
