How to Check Your Battery Usage on the iPhone with iOS 12 Battery Health Tracking

Apple's new operating system, iOS 12, is supposed to bring improved battery performance to every iPhone, even older ones. You don't have to take anyone's word for it though, because one of the new features being rolled out with iOS 12 is improved battery health tracking (Battery Health was first introduced with iOS 11). Your iPhone's battery usage is broken down app by app in this new set of data so that you can see not only the percentage of battery life used by each app but also how long you spent on individual apps. Let's get started learning how to check your iPhone's battery health.
