What are the best ways to extend battery life on the iPhone6?

Turn off Background App Refresh and Location Services for the apps for which you don't need to have those active. Charge your phone when it needs it. Don't bother with "closing" apps or "battery saving" apps.

Thank you so much for your thoughtful reply. I take the implicit message is to be realistic. Charging is part of iPhone use and power drains batteries. But charge appropriately when really needed.

You're very good at reading between the lines! 😉
