As a result, the Cupertino company has clarified in a new support document, on its Chinese website, that the random shutdowns that some customers have been experiencing may affect more iPhone 6s models than previously thought. In the statement clarifies that a software update can solve the problem on devices that were not model iPhone 6s that were manufactured between September and October 2015, which is offering a free battery replacement program.
At the moment, even Apple itself does not know what the problem is with these defective units, so he reported that he needed additional diagnostic data to determine the exact cause of the failure.
Here's the Apple statement:
"Outside the affected lot, a small number of customers reported an unexpected shutdown. Some of these turned off may be normal because the iPhone will shut down to protect its electronic components. For more information, we'll add an additional diagnostic item for the iOS software update to be released next week.
This feature will pick up a variety of information over the coming weeks that can help us improve algorithms for managing battery performance operations and shutdown operations. If these improvements are achieved, we will deliver them through other software updates. "
In other words, an upcoming iOS software update will incorporate additional diagnostic capability to help gather information about the affected devices.
If the company determines which devices suffer random off because of a problem that can be corrected in software, probably they will release a patch in future software updates to fix this flaw.
Three weeks ago, the company proposed a worldwide free battery replacement program for iPhone 6s units manufactured between September and October 2015 that cause random shutdowns when the battery charge level falls below 30% .
