Apple, Inc., released iOS 8 to users on Sept. 17, and it has instantly been the talk of the town ever since, as is evident in numerous reviews, tips and tricks. 

At a glance, the update seemed to have done nothing new to the interface and design.

However, Apple did not intend iOS 8 to bring drastic changes on "how it looks", but would bring new things to its "how it works" division.

One of the issues that the update tries to address is the battery life dilemma of every iOS 8 device user.

With iOS 8, users are now able to see how much battery life each iOS application is eating up.

To spot the notorious battery-draining apps, simply launch Settings from the main menu, navigate to General, and under Usage is Battery Usage.

From there, a user will be given a list of apps accessed in the last x amount of hours, and "shows proportion of battery used by each app when iPhone is not charging".

A user can also choose to see which apps have expended the most juice over the last 24 hours or the "last 7 days."

Once a user identifies the battery-hogging apps, he or she can decide what to do – delete or retain.

Gmail, Facebook and Twitter may occupy the top section of the list, but these frequently used apps you probably want to keep around. However, apps that are not used often but top the list, these are the ones that a user might want to consider removing.

Now, if a "background activity" appears in the description, this means that it runs even when the app is not in use, which obviously can drain the battery.

Aside from the iOS 8 battery-life tracking, Apple has improved the synchronization of hardware and software to enable energy-saving capabilities.

"iOS learns when you like to use your apps and updates the content in them at power-efficient times, like when your device is already in use and connected to Wi-Fi. So the content in your favorite apps stays up to date without a major drain on your battery."
