My Choice

If I were choosing between these two phones, I would personally go for the Samsung Galaxy M15. Here's why:

As a frequent user who is on the go most of the day, the battery life is the most important factor for me. The significantly larger 6000mAh battery in the M15 is more important to me than the better camera or brighter screen of the Redmi Note 10S. Additionally, I value having the newest version of Android, which the Samsung M15 offers. While I appreciate the better GPU of the Redmi Note 10S, the Dimensity 6100+ chipset in the M15 is powerful enough for my daily needs of social media, browsing and light gaming. The smoother 90Hz display also contributes to a better user experience. Although the camera is slightly inferior and the brightness is less, it does not impact me as significantly as the battery life would. Therefore, the Samsung Galaxy M15 better suits my specific use case.
