How full is your storage? and do you have lots of apps installed? And also running background apps… This can negatively impact performance during gameplay.
I have a Samsung S23 Ultra, and a Samsung S25 Ultra, both seems fine, with max settings, running at 60 FPS stable on the S23… The S25 can even run at 120FPS if unlocked screen update hz on phone settings (I lock to 60fps because I don’t think more than that is needed).
I even have some recent clips here (OG gameplay is on s23u and the current season on s25u. Don’t ask me why I use two phones xD)
Oh, I use the FHD (2340x1080) screen resolution on both phone settings, I don’t use the QHD+ (3120x1440)… I have not tested it to see how it impact the performance :/
