How to maximize my iPhone 5s battery life right out of the box?

I know about all the little things you can turn off, adjust, disable, etc.
But what about right when it comes out of the box?
I know you have to activate your phone, but you also need to charge it.
Is it better to charge it until the battery is full and then activate it, or do both simultaneously, or activate it first? Or does it not affect it at all?

Go to your Date and Time setting: turn off the SET AUTOMATICALLY function. Saves about 30% battery life.

Turn off location services.

Disable wi-fi when you are not using it.

Set phone to airplane mode when not in use.

If that battery is charged then I would just use it until its under 20% or so, then charge it up that night, thats what I've always done
