My Choice
If I were choosing between these two phones, I would choose the Samsung Galaxy S21 5G. Here's why:
While the Nokia C31 has a larger battery and screen, my priority is overall performance and user experience. The Galaxy S21's significantly superior display (AMOLED with 120Hz), vastly better chipset, and its comprehensive camera system make it a much more compelling option for me. I value having fast app loading, a fluid user interface, excellent camera capabilities, and having the flexibility of wireless charging. While the Nokia C31's large battery and budget friendly price point is nice, it falls too short in other key areas for my preferences. The performance difference is a big deal, and the superior screen of the S21 makes for a far more enjoyable experience. Even though it's an older phone, the S21 offers a smoother, more powerful experience, and for me, that makes it a better choice.
