Users curious about what's draining their iPhone or iPad battery can now see exactly where that precious electricity is being consumed, thanks to a new battery usage feature found in iOS 8.
The new battery tracking feature can be found in iOS 8 by opening the Settings application and navigating to General, Usage, Battery Usage. The list will take a second to populate before displaying a list of apps and how much energy they are consumed.
Apps can be listed in terms of battery usage over the last 24 hours, and over the last week. The percentages displayed show the proportion of battery used by each application when the iPhone is not charging.
In addition to applications, Apple also includes the iOS home and lock screen, as well as backup and restore services, to identify battery drain that may be coming from other places.
Apps that run in the background, either for location tracking or other activities, are also identified in the list.
Even if a user has uninstalled an application, it will remain in the list to show how much power the software was using before it was removed.
Apple also provides information on usage and standby time of an iPhone or iPad since the device was last charged. Such times are shown after the iPhone has been fully charged.
