Apple says it will replace the batteries on some models of the iPhone 6S that could unexpectedly shut down, but pose no safety risk.
The company says the smartphones affected were manufactured between September and October of last year. If your phone is affected, Apple will swap in a new battery free of charge.
The battery issue involves "a very small number" of iPhone 6S models, according to a support page on Apple's website detailing how to replace the device's battery.
Users can contact an authorized service provider or a local Apple store to have the battery replaced. The replacements will not involve any of the wireless carriers that support the iPhone.
Reports of iPhone 6S devices unexpectedly shutting down date back to October of last year, weeks after Apple launched the smartphone, along with the larger iPhone 6S Plus.
Apple is not the only company having to deal with issues related to their smartphone's battery. Earlier this year, Samsung discontinued the Galaxy Note 7 smartphones after reports overheating batteries could cause the device to catch fire or explode.
