Korean agency considering an investigation into alleged iPhone 6s battery problems

The Korean Agency for Technology and Standards (KATS) is considering an investigation of alleged iPhone 6s shutting down randomly in case they represent a battery safety issue, according to the Korea Herald. 

"The agency is well aware of recent iPhone issues and is taking a close look at it," a KATS official told the publication. However, no investigation has yet been launched.

Apple has admitted that iPhone 6s devices manufactured between September and October 2015 showed battery malfunctions. The company will replace the battery on these smartphones for free.

However, there are media reports in China that other iPhone 6 smartphones also power off randomly with battery remaining for no apparent reason. Also, a Chinese consumer watchdog reported several users have claimed that their handsets caught fire or exploded. Apple has denied these reports.
