My Choice
If I were choosing between these two phones, I would pick the OnePlus 9R. My primary usage revolves around performance-intensive tasks, gaming, and multimedia consumption. The OnePlus 9R offers a superior processor, faster refresh rate screen, a much more capable camera, and fast charging, which are critical for my needs. While the Samsung Galaxy A15 has better battery life and a brighter screen, I value the smooth performance and overall experience that the OnePlus 9R provides. I am generally more likely to be near a power source to offset the battery disadvantage, and the much better display and camera quality are compelling. The significant performance difference is a bigger factor for me than the battery life and brighter screen advantages the Samsung Galaxy A15 offers, and the faster charging of the OnePlus helps to mitigate some of the battery concerns.
