"Closing" apps is pointless unless you are running 50 apps.
Apps don't background in the sense you think they do, it's faux multitasking, they suspend/hibernate which is why it takes a lot of "background" apps to affect battery life.
FWIW I don't do any of that and get 2 days of use out of my 4.
I have 5 mail accounts set to fetch every 15 minutes.
In my experience the biggest battery killer is signal strength/availability.
In FL I get a full day, but just barely.
In CA I get a day.
In NY/NJ I always need to charge around 4-5 pm.
In TX, 2 days is normal.
