iPhone 6s battery issue more widespread than thought, will release iOS update

Timothy Phillips Posted On 06/12/2016

It was reported last week that battery components in a particular batch of iPhone 6s’ were exposed to the air for too long before assembly. Because of this some users devices had batteries that would cut out and cause an unexpected shutdown. While Apple initially indicated that it was a limited number of devices, it appears the issue is more widespread.

In an updated statement not yet translated to English, Apple states that they need additional diagnostic data to determine the specific cause of the problem.

Outside the affected batch, a small number of customers reported an unexpected shutdown. Some of these shutdowns may be normal, because the iPhone will shut down to protect its electronic components. To gather more information, we will add an additional diagnostic feature to the iOS software update that is released next week. This feature collects a variety of information in the coming weeks that may help us improve algorithms for managing battery performance and shutdown operations. If such improvements can be achieved, we will deliver them through further software updates.

Apple has already launched a repair program for defective 6s devices. Certain serial number ranges have ready been listed as defective, but more units could also have potential symptoms. The following characters located in the 4th and 5th position of your iPhone’s serial number represent defective devices:

Apple retail stores should have batteries for replacement although sources are reported that some stores are having to wait for extended stock to arrive. Stores are only replacing parts for users specifically referring to the battery issue. The replacement program will cover affected iPhone 6s batteries for 3 years after the first retail sale of the unit.”
