I would say bettery is about the same of iOS 26, but mine is quite cooked (78% battery health) and I have to replace it.
Performance is for sure better. Not as much as I expected (I expected to notice it everyday), and I can't give you a number, but I remember that I noticed stuff being faster the first couple of days that I installed the beta, but now I got used to it
