Poor iPhone battery life after iOS 26 update

Ever since I upgraded my iPhone 15 Pro to iOS 26, I have noticed that the battery life is noticeably worse than in iOS 18, my battery life going from 100% in 4 hours used to stay above 70%, now it dips below that much sooner. I have heard that indexing usually causes rapid battery drain at first, but my phone has cooled down and has been about more than 12 hours but my battery is still draining fast. Any solutions to this? My battery health is currently at 88% and says it is normal health. I had to type this on Mac becuase for reason in the mobile version of Apple's website, the keyboard just hides when I try to type.
