Owners of various iPhone models have been complaining of a bug in Apple's iOS that causes the smartphones to suddenly shut down, at times even while the devices have 30 percent remaining in their batteries.
As previously reported, the 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.
There are also numerous threads on the iPhone subreddit discussing the issue, wherein several users complained about the same problem of having their iPhones shut down despite displaying sufficient charge levels.
iOS Battery Problem Not Limited To iOS 10
The conditions to experience the reported battery problem look like they highly vary between users. The point of the iPhone shutdown does not only occur at the 30 percent battery charge level, as there have been reports of the issue happening at slightly below or above the 30 percent mark.
While majority of users have said that they are experiencing the problem after upgrading their iPhone's operating system to iOS 10.1 or iOS 10.1.1, there are a few who claim that they are also seeing the battery drain issue even while on another operating system such as iOS 9.3.5.
The known list of smartphones that have been affected by the problem include the iPhone 5s, iPhone 6, iPhone 6s, iPhone 6s Plus and the iPhone 7.
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.
