Apple explains why iPhone 6s batteries are failing

The iPhone 6s has been back in the news recently following Apple’s admission that there are a series of device that has defective batteries. It has an exchange program under way, but the problem seems to be  bigger than was initially thought. Now, Apple has an explanation for what’s going on.

“We found that a small number of iPhone 6s devices made in September and October 2015 contained a battery component that was exposed to controlled ambient air longer than it should have been before being assembled into battery packs,” Apple explained to Business Insider on Friday. “As a result, these batteries degrade faster than a normal battery and cause unexpected shutdowns to occur. It’s important to note, this is not a safety issue.”

That last bit comes as a bit of a surprise. Apple explains that the iPhone 6s is shutting down on purpose to prevent any danger being presented to the end user. So, really, the iPhone 6s is working properly while the battery isn’t. This is different from, say, the Galaxy Note 7, which wasn’t shutting down but instead would ignite when the battery failed (for very different reasons.)

iPhone 6s battery failures are an inconvenience, but not a safety concern

Apple builds on the explanation that this is not a concern for customer safety. Instead, it’s just a very annoying problem for folks who own iPhone 6s units with defective batteries. “We also want our customers to know that an iPhone is actually designed to shut down automatically under certain conditions, such as extremely cold temperature,” Apple explained, showing that other circumstances can also cause an iPhone to shut down on purpose. “To an iPhone user, some of those shutdowns might seem unexpected, but they are designed to protect the device’s electronics from low voltage.”

Good to know. Your iPhone 6s isn’t going to just burst into flames, but if it’s shutting off when it says you really have 30-percent of life left, you should probably take it in for an exchange. You can check if your unit is part of the affected bunch by visiting this page.
