Last month, Apple, after conducting an investigation over several complaints of random shutdown of iPhone 6s series, revealed that there was a lapse in the assembling process causing devices to switch off without warning despite having surplus battery life.
Apple honestly accepted its fault and announced to replace the batteries of iPhone 6s manufactured in September and October of 2015.

Now, we have come to learn that the government-run China Consumers Association (CCA) has told Apple to take action and also admit lapse in delivering proper service to affected parties.
It has also asked Apple to extend the replacement program to iPhone 6, iPhone 6 Plus and iPhone 6s Plus, which are also said to be having faulty batteries.
CCA had sent a notice to Apple China on November 15, but it never got proper response from the company. CCA sent a more scathing letter to Apple on November 30.
"Apple should do the job of stocking spare parts, replace the battery to improve efficiency, protect consumer Normal communication needs. China Consumer Association will be concerned with the community and to promote the unusual shutdown of Apple's mobile phone problem solving, safeguarding the legitimate rights and interests of consumers," CCA letter (in Chinese translated to English) states.
However, Apple has re-iterated that the issue is limited to iPhone 6s models and launched a web tool to help users identify the device with faulty cell.
