On its Chinese language website, Apple is admitting that the battery issue making some iPhone 6s devices shut down unexpectedly is affecting more models than previously thought. The company has said that some iPhone 6s devices made between September and October 2015 contained a faulty battery component, and Apple is offering free battery replacements based on the devices’ serial numbers — but new cases are cropping up outside that initial batch.
To get more information on the problem, Apple is releasing a diagnostic in the next iOS update, scheduled for release next week. Apple said the feature “collects a variety of information in the coming weeks that may help us improve algorithms for managing battery performance and shutdown operations,” pledging to roll out an update to patch the problem once they figure it out. Apple is still offering free battery replacements for some affected devices, but only within the September and October 2015 production range. [via 9to5Mac]
