Yes with android it is best to leave everything for a week or 2 before trying to "save power". Things to note coming from an iphone, iphone does have better standby time however android tends to be better with battery when using apps. People that say they get 9 hour on screen time tend to hack and turn everything off so don't expect to get the same on screen battery life as you read on the internet as some of them are just bulls***
Let the phone kill apps in the background, there is no need to manually close things anymore. Let the OS do it all.
