My Choice

If I were choosing between these two phones, I would personally lean towards the Samsung Galaxy S21 5G. While I appreciate the compact size of the iPhone 12 mini, the practical benefits of the S21's larger, 120Hz display, significantly longer battery life, and more versatile camera system outweigh the drawbacks for my personal usage. I often find myself consuming media, gaming, and working on my phone for extended periods, making the larger screen and better battery essential. The fingerprint sensor is also a plus for security. Although the iPhone has a superior processor, both phones are fast, and the advantages of the Samsung outweigh this single benefit in the real world. Additionally, I find the open-endedness of the Android platform more in line with my preferences. I also appreciate the reverse wireless charging.
