I am experiencing some unusual behavior with my Samsung S23 Ultra after installing the One UI Beta 8. Initially, everything seemed to be working well, but I've since encountered some issues. Specifically, when the battery level drops below 15%, the phone's performance becomes noticeably sluggish, and there are audio glitches. Furthermore, the device frequently shuts down at around 11% or 7%, which was not the case previously. I attempted to uninstall the beta version, but the official update has since been released, and the problems persist. My phone's battery is also draining much faster than usual. I understand that a major update can sometimes cause the phone to adjust to new usage patterns, but it has been over ten days now. I am curious to know if others are experiencing similar difficulties.
