How to keep an IPhone six permanently turned on so that it doesn't fall asleep unless you press the button?

Yes. You keep the iPhone six plugged into the charger all the time rather than use the battery to use the phone.

In the Settings, there's a way to determine how long before the phone sleeps. You do know that this will eat your battery like Cheetos.
