iOS 8.1.2 Update Fails To Solve Battery Issue
It seems that the many different steps that Apple has taken to fix whatever battery issues related to iOS 8 has failed in the past few months, and most of the time, such battery drain is attributed to third party apps as opposed to the operating system itself – however, managing the different kinds of apps on your iOS device in an intricate manner is not exactly foolproof.
Another way might be to tinker around with the screen brightness settings, or perhaps even altering the “location settings” on different apps. All in all, iOS 8.1.2 is not going to help improve the battery life on your device by a phenomenal margin, so keep on looking out for a future fix!
