Apple blames air exposure for iPhone 6s battery defect

Samsung isn't the only company having battery problems this year: according to a document posted to Apple's website, the recent slew of iPhone 6s battery failures (which have led to an exchange program) are the result of a component being improperly stored before battery assembly, reports ZDNet. The exposure of the component to air leads to faster battery degradation and failures.

The manufacturing issue has no impact on safety and poses no risks at all to consumers, Apple stresses, eager to avoid comparisons between the iPhone 6s and Samsung's Note 7 battery woes. If you are an iPhone 6s owner, check here to determine if your phone is affected by this defect.

The 6s's battery defect again draws the attention of critics to Apple's iPhone warranty service. Just a few weeks ago, Apple was chastised by some for its tepid handling of repairs for the iPhone 6 Plus's "touch disease".
