[Galaxy S22U] Battery diminished

I have been a long-time Samsung purchaser of many of their products, but when it comes to their mobile devices, I have really lost a lot of respect for Samsung.
Right now, I am still using my S22U, which, by the way, still takes outstanding photos in my opinion and is still running smoothly; however, after the last system update, while still being on 8.0 (which S22U users were told we would get 8.5, but they cut us out), the battery has absolutely diminished. I have also had to stop notifications on 85% if not more of my installed apps, plus use dark mode. Those option changes have helped me out tremendously.
My major point is I felt there was no need to spend $1,500+ for such little updates, so here we are. The S27U is finally here, which for me will be a huge update and upgrade. I absolutely hate the device's body. Why, Samsung, did you do that? I hope I like it in my hands; otherwise, it is going to be time for me to switch manufacturers. I am thinking Google or OnePlus, but right now I feel like I am stuck between a rock and a hard place. I am not a huge gamer, but if I did want to, I want the option to be there.
