A few thoughts: When an app is removed from the app switcher, it needs some 
battery power to reload its data the next time it is loaded. I agree that some 
apps drain power more than others, I generally leave them alone if I think I am 
going to use them within, say, an hour or so, or remove them if not. That goes 
for all apps if I know I probably won't use them for,  the rest of the day. 

Other things I do: I don't have mail checking for mail until I turn it on, when 
it is going to check again for mail. I have very few notifications turned on, 
although that is a personal decision, use them if you need them. 

Finally, even if you have brightness set to zero, leaving the screen unlocked 
drains battery. Although I have mine set not to lock,  I lock it if I don't 
need it to be unlocked, even if I am using a program where I can lock it and it 
not interfere with my using the program. I have set it to lock after a given 
amount of time, but prefer to lock it myself, except when I forget, come back 
in a couple hours, and find my battery is down by some double digit percentage. 
Oh well.

only thing to do is to try it and see if there's any difference…
