The iPhone 6 and 6 Plus were designed to offer up to 14 and 24 hours of usage, thanks to iOS 8 handling power consumption in an intelligent way. And if it doesn't, it means you might have your settings all jacked up.
Since the inception of iOS 8, there are several new features that are switched on by default, and thus settings you can tweak to make your new iPhone go all day. By the time you've made your way to the end of this article, you'll be surprised at how long the battery can actually last.
You know what they say, every little bit goes a long way.
Oversharing your every move
iOS 8 brings with it the ability to share your location with your friend via Messages via the little Details tab. It’s a pretty neat feature, but you don’t really need it switched on the whole day, and have your friend tracking your every move right?
Do this instead: Go to Settings, Privacy, Location Services, and Share Location From to disable it. Or choose to share your location from another device which has better battery life, like your iPad for instance.
