My Choice
If I were choosing between these two phones, I would pick the Samsung Galaxy S21+ 5G.
Here's why:
- Performance is King: As someone who uses their phone for a variety of tasks from gaming to photography to productivity, the S21+'s chipset provides a much smoother, more responsive experience. The Poco C40 would feel slow for my use case.
- Display Matters: I heavily consume media on my phone, and the S21+'s AMOLED screen with its high resolution, 120Hz refresh rate, and brightness is crucial for an enjoyable viewing experience. The Poco C40's screen would feel outdated and lacklustre.
- Camera Versatility: Photography is important to me, and the S21+'s telephoto lens, higher resolution selfie camera, and 8K video capabilities are huge advantages. The Poco C40's camera system would severely limit my ability to take quality pictures.
- Future Proofing: The S21+'s advanced connectivity features (Wi-Fi 6, advanced Bluetooth, eSIM) make it a more future-proof device. Additionally, the S21+ is likely to receive more software updates.
While I appreciate the Poco C40's larger battery and included charger, the overall performance, display, and camera advantages of the S21+ far outweigh these benefits. I would choose the Galaxy S21+ despite the lack of a charger and smaller battery in box. For me, the higher cost of the S21+ is justified by the better user experience and features it offers.
