Apple Clarifies Why Some iPhone 6s Suddenly Shut Down At 30% Battery.

About a fortnight ago, many Apple iPhone users complained of their iPhone 6s devices getting shut down abruptly. To this, Apple announced a free battery replacement for iPhone devices made in September. However, the company did not divulge any details as to why the problem was occcuring. However, now the company has come out with an explanation.

Apple has posted a message on its Chinese website explaining that the issue is related to some batteries having been overexposed to "controlled ambient air" during the manufacturing process.

"We found that a small number of iPhone 6s devices made in September and October 2015 contained a battery component that was exposed to controlled ambient air longer than it should have been before being assembled into battery packs. As a result, these batteries degrade faster than a normal battery and cause unexpected shutdowns to occur. It's important to note, this is not a safety issue."

Apple further explained that iPhones are designed to shut down automatically under certain conditions, such as extremely cold temperature. In this case, some iPhone 6s models are shutting down with around 30% battery remaining to protect the device's internal components from low voltage.

Apple launched a repair program earlier this month wherein it was offering free battery replacements for affected iPhone 6s models. But this was only for devices falling within a specific serial number range manufactured between September 2015 and October 2015. Apple has since launched a tool to check if your serial number is affected.

Additionally, Apple is also offering refunds to customers who have previously paid to have their iPhone 6s battery repaired or replaced (only those manufactured between September-October 2015).
