Turn off Siri feedback from apps. Even after doing all the things suggested here it only improved my battery life by about 25%. It would still go down from 90% charged at 9 am to 30-40 % by noon, without me doing much on my phone. However, by chance (since I never use Siri because I don't like big brother listening in on my life) I went to "Siri and Suggestions" and turned off every single app that sends feedback to Siri even though I had Siri turned off. My battery life improved by 80%!

Turn on dark mode if you have IOS 13 or later. To do so, go to settings, brightness and change from light mode to dark mode by selecting “Dark mode”. This should make your battery last longer.
