Remember the off switch?

Thankfully, I have another option available to me that other might not even consider. One that might be helpful to others as well. One that may help the battery last throughout the day or, at least, longer than it otherwise has been without the battery case… Use the iPhone less. Less "checking in" on Twitter. Less taking photos. Less using it to write. If the battery does die, prematurely, before I’m able to connect it to a power source, learning to be comfortable with that. Let it die.

Having used the iPhone 6 for almost a year I do crave a smaller phone. It's simply too big and with the big screen comes a bigger screen for distractions. I'm also considering Apple new smaller iPhone when it's released.
