Apple explains the battery problem leading to iPhone 6s shutdowns
It is a couple of weeks since Apple announced a battery replacement program for iPhone 6s handsets suffering with random shutdown issue. At the time, the company gave nothing away about what the root cause of the problem was, but now it has opened up.
In a posting on its Chinese website, Apple confirms that the shutdown problems were indeed related to a battery problem. Specifically, the company explains that it was “a battery component that was exposed to controlled ambient air longer than it should have been”.
