My Choice
If I were choosing between these two phones, I would choose the Samsung Galaxy S21 Ultra 5G. While the Infinix Hot 12 Play's longer battery life is appealing, the overall experience offered by the S21 Ultra is far superior, especially with its much better display, performance, camera capabilities and fast charging speeds. As someone who values high-quality visuals, smooth multitasking, and versatile photography, the S21 Ultra better suits my needs.
