Apple Have Said they'll Offer Free Battery replacements for your iPhone 6s...only if it's Shutting down unexpectedly

Apple have said they'll offer free battery replacements to those who are having issues with unexpected shutdowns on their iPhone 6s.

Apple have said they'd replace the batteries for these devices at its branded retail stores and authorized service provider centers for free.

So if your iPhone 6s has this problem, Apple says there’s no cause for concern as it isn’t a safety issue. Plus, the company believes it only affects devices within a limited serial number range that were manufactured between September and October 2015. 

This is different from the 'Touch disease' problem some iPhone 6s suffered earlier. Apple announced a repair program for that last week,

Before going ahead with the replacement though, you should backup your data, erase your settings and turn off the Find my iPhone security feature. To erase your data, you can head over to Settings > General > Reset > and click on Erase all Content and Settings. Apple also notes that the program covers iPhone 6s batteries for three years from first retail sale of the unit and battery replacement does not extend the standard warranty coverage of your device.

So once you've sorted this out, you should be able to get your iPhone 6 battery replaced.
