How do I enable 'Send Last Location" in iOS 8?

"Send Last Location" is a new Find My iPhone feature in iOS 8 that could prove helpful if you lose your iPhone. It simply sends the phone's location just before the battery dies, which is crucial if you are far from your phone and trying to track it down, or if you didn't even realize you lost it before the battery died. To activate the feature, simply go to Settings -> iCloud -> Find My iPhone and toggle "Send Last Location" to on. Of course make sure "Find My iPhone" is toggled on as well.
