Apple Inc. said that it would be offering free battery replacements for the iPhone 6s after reports on faulty units surfaced in China.
According to the tech giant, the replacement will be available for its customers worldwide, but the service will only be limited to iPhone 6s devices that were manufactured between September and Oct. 2015.
Apple's announcement came on the back of multiple reports by Chinese customers, led by the China Consumer Association, on iPhone 6s devices unexpectedly shutting down despite having half of their batteries still full.
"In view that Apple iPhone 6 and iPhone 6s series cellphones in China have a considerable number of users, and the number of people who've reported this problem is rather many, China Consumer Association has already made a query with Apple," the CCA said in a statement, as translated by Fortune.
The company stressed that this issue is not a safety concern but is only exclusive to units made within the said period.
This will be the second time in the last three years that Apple has issued an iPhone battery replacement for free, wrote the New York Times. This also comes months after Samsung's massive recall of Galaxy Note 7 phones, following widespread reports on exploding batteries.
Owners of faulty iPhone 6s units need to visit any Apple retail store or an authorized Apple service provider. They are required to have the serial number of their respective units checked so they can have the service free of charge.
The NYT, however, said that Apple's battery replacement program left some questions unanswered. This includes "when Apple learned of the problem and why Apple thinks the shutdowns are related to the battery."
"Apple also didn't specify how it concluded only phones made in those two months are affected and whether those phones used a different battery, or battery supplier, from other phones," the NYT wrote.
