Apple released iOS 11.4 couple of weeks back and while the operating system fixes some of the key issues, it seems to have led to a new issue. Some iPhone users are claiming that the update has resulted in their devices draining faster.
In a post on Apple’s forum by user Zide99, iOS 11.4 has been reported to be the cause behind rapid battery draining issues on an iPhone 6 unit. Comments on the thread also claim that battery percentage on their devices has gone down within minutes with no apparent reason. One comment suggests that unintended activation of personal hotspot has been the major battery hogger in iOS 11.4, utilising as much as 47 percent of overall battery usage.
On Apple’s official forum, an iPhone user posted “I have the same issue with my 6S+. It was fine before the update. And my battery health is at 90% yet I just watched my battery % drop from 50% to 20% in a matter of minutes while not using it. I’ve looked through all the settings and can’t see anything I’ve previously had turned off turn back on with this new update in regards to saving battery life. Whatever it is that’s causing it they need to fix it ASAP.”
