- How important is battery life? (If you need a long battery life, Poco M5s has a significant advantage; if not, V21 is adequate).
- Where do you mainly use your phone? (If indoors, the V21 display is good enough; if outdoors often, the Poco M5s's brightness is a must).
Scenario-Based Recommendations:
- Scenario 1: A user takes lots of selfies, but has access to power throughout the day. Recommendation: vivo V21 5G for the better selfie camera.
- Scenario 2: A user plays a lot of mobile games and travels without easy access to chargers. Recommendation: Xiaomi Poco M5s for its performance and battery life.
- Scenario 3: A user uses their phone heavily outdoors and watches videos often, but takes few selfies. Recommendation: Xiaomi Poco M5s for its screen brightness and stereo speakers.
My Choice
I would choose the Xiaomi Poco M5s. While the vivo V21 5G has a superior selfie camera and a smoother display, the Poco M5s offers a more balanced overall package. The significant advantages in performance, battery life, display brightness, and the inclusion of stereo speakers make it a more practical choice for me. Additionally the inclusion of a side mounted finger print sensor which is a better location than the basic sensor of the V21 5G, makes it a superior choice. While the front-facing camera is not as good, it is still adequate for my needs. The improved battery life, performance, and outdoor usability are key factors that address my typical usage scenarios.
