As previously reported, the iOS bug issue first appeared with the iOS 10.1 update, and has continued into iOS 10.1.1. It seems that the iOS 10.2 beta has also not addressed the problem, which means that affected users will be venting out their frustrations a bit longer. iOS Battery Drain Bug Experiences In the opening post of an already 15-page thread on the issue in Apple’s support forums, user Mjolcresure narrated that upon updating his iPhone 5 to iOS 10.1, he has experienced the battery of the device jumping from 30 percent down to 1 percent, and then the iPhone 5 shuts down. Upon connecting a charger, the smartphone reboots to show that it still has a 30 percent charge, and when the charger is removed, it will continue to stay on as it would with a battery at 30 percent. That opening post was made on Nov. 3, but the complaints on the issue have not ended. At the time of writing, the last user to post in the thread said that the same problem is being experienced on the iPhone 6s after upgrading to iOS 10.1.1. When Will Apple fix the iOS Battery issue ? Apple has not yet acknowledged the battery problem that a significant number of users are complaining about. With a fix to the problem seemingly not to be included when iOS 10.2 is released, Apple has either not yet been made aware of the problem or it has not yet figured out a solution for it. Last week, Apple announced a battery replacement program for a handful of iPhone 6s units that are suddenly shutting down. There is no clarification on whether this is related to the wider battery drain complaint or if the problem only concerns the iOS.
