iOS 10.1.1 launched about a month ago, and, for the most part, the update seems to have been pretty smooth. I don’t really have any issues with the software on my iPhone 7 Plus, for example.
Unfortunately, the same isn’t ringing true for everyone.
News.com.au recently covered the topic, noting that some users are complaining that their iPhone batteries are showing a 30-percent charge before the phone turns off as if the battery had just completely drained in a moment. Some users say the issue started with iOS 10.1, others say it began with the latest iOS 10.1.1 release.
“It jumps from 30 percent charge to 1 percent in a few seconds then shuts down,” one user told the news outlet. Another user explained that the device seems to charge to 30 percent just as instantaneously, suggesting there’s a bug where the iPhone thinks it has 30 percent charge when indeed there’s nothing left.
This isn’t normal, so you have every right to be upset if you’re finding that the battery drain is affecting your smartphone use. It’s also kind of dangerous: if you think you have 30 percent of your battery left but actually have more like 1 percent, and there’s an emergency, you might not have a phone at all. Plus, you pay for reliability with your phone, so you should expect to be able to use it without worrying about it turning off. As it turns out, Apple is actually dealing with this issue for some of its iPhones and is already issuing replacements.
iOS 10.1.1 battery drain: Here are your options
I noticed that there seems to be a common thread among commenters; many seem to be using iPhone 6 or iPhone 6s units. As PCMag also suggests, it’s possible this is related to the defective batteries that have appeared in some iPhone 6s phones, which cause the device to shut down randomly.
If you have a phone that’s acting this way, it’s certainly worth speaking with Apple to see if you can participate in the replacement program.
If it is a software bug, then my guess is Apple will address it in the next update. In the meantime, try carrying a charging pack with you or, if you have the skills, downgrade to the last version of iOS 10 that didn’t cause battery drain issues.
