iPhone 6s turning off at around 20-30%

My iPhone 6s is turning off at around 20-30%. I've tried multiple times to calibrate the battery using Apple's method by plugging in to turn on until the device is at 0% but with no success.


The phone was bought at launch (September 2015). I never had these problems with the 2 other iPhones I had before.


Seems like this is a common problem with multiple models.


How can I fix it?

iPhone 6s, iOS 10.1.1

Try to reset your device. This won't delete your data stored on this device.


  • Press and hold the Sleep/Wake button
  • Press and hold on the Home button
  • Keep holding both buttons until the display turns off and back on with Apple logo on it.


Alternatively, you may go to Settings - General - Reset - Reset All Settings


If this does not help, restore your device to factory settings. Note that this will erase the data from your device.

Take a look this Apple Support article: Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support.


As a final step, try the recovery mode. Turn your device off, then plug it to your computer with the home button pressed. Keep the Home button pressed until you see the iTunes logo on the screen of your device. After that on your computer you should see the iTunes window saying your device needs to be restored to factory settings. Click on the restore button.
