Apple will finally let users know what apps are draining their battery life with new iOS 8

Apple will finally let customers know what is draining the battery life of their devices with the introduction of iOS 8, their latest mobile operating system.

This new system gives users a display screen that allows them to see what apps they have been using, and just how much power those apps are taking up on their device.

Even better, the mobile software is available across all devices, not just the recently introduced iPhone 6.

Users who have the iOS 8 will be able to see a display of all their apps on a new battery usage screen that ranks, from highest to lowest, the percentage of phone power each app has used.

This then allows users to adjust their phone's settings for optimum battery life. 

Apple is currently riding a high following the release of the new iPhone 6, which sold a record-breaking four million units in just the first 24 hours of pre-order sales.

That number doubles the company's previous pre-order record of two million devices for the iPhone 5 back in 2012.
