I've done everything that I suggest to others, which includes what you have said..
My S25 Ultra shipped with One UI V7.0, and until the April 1st Security Patch, I was getting great battery life.. but since April 1st Security Patch, and still after the May 1st Security Patch, I'm having to charge my phone twice a day... I haven't had to do this, since my Skyrocket more than a decade ago!
It's not just being reported here, but on Samsung Members US, as well as Sammobile & SammyFans.
The May 1st Update was just a Security Patch, hopefully Samsung will have figured it out for the June 1st Security Patch, which is supposed to include a variety of fixes.
