iOS update to diagnose iPhone 6s battery issues as more devices affected

Apple is planning to release an iOS update that can help to diagnose iPhone 6S devices that are affected by a battery issue causing unexpected shutdowns.

Initially, the company has claimed only devices manufactured between September and October 2015 were being affected by the issue.

Apple recently launched a tool to allow users to discern whether their device was eligible for a free replacement.

However, the firm has now discovered ‘a small number of customers outside of the affected range’ are reporting the issue, and is promising an iOS update next week with ‘additional diagnostic ability.’

In an updated message on the firm’s Chinese support site, Apple added (via MacRumors): “A small number of customers outside of the affected range have also reported an unexpected shutdown. Some of these shutdowns can occur under normal conditions in order for the iPhone to protect its electronics.

“In an effort to gather more information, we are including additional diagnostic capability in an iOS software update which will be available next week. This will allow us to gather information over the coming weeks which may potentially help us improve the algorithms used to manage battery performance and shutdown. If such improvements can be made, they will be delivered in future software updates.”

Apple has continued to emphasize that this is not a safety issue, a la the Galaxy Note 7.
