IOS 14.5.1 battery drain

When I upgrade to IOS 14.5.1 (iphone XS) pull my battery drain 15% in 3h. Today I install 14.6 beta, but nothing new - 17% in 3h, no app using. Now I m in 14.7 beta, I will report after 3-5h. Battery health 86%. I m not alone, what I read in net.

Beta 14.7 nothing new. 5% /1h drain. You will fix?
