When Apple announced an iPhone 6s battery replacement program last week, identifying select models that might be eligible for a free repair due to unexpected shutdowns, it only specified manufacturing dates for potentially affected devices. It recommended customers take a trip to an Apple store or authorized reseller if they are experiencing issues to check if they are eligible for a repair. But there’s a quick and easy way to check if your device is eligible at home, using the same process that Apple repair staff will be using in stores…

Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015…. Your iPhone will be examined prior to any service to verify that it is eligible for this program and in working order.

Apple is replacing batteries for what it said is “a very small number of iPhone 6s devices” that were manufactured between September and October of 2015 in a limited serial number range. Here’s how to check your device:

  1. Locate your iPhone’s serial number (you can find the serial number on the back of your iPhone and in Settings>General>About).
  2. Check for the following characters located in the 4th and 5th position of your iPhone’s serial number:
  • Q3
  • Q4
  • Q5
  • Q6
  • Q7
  • Q8
  • Q9
  • QC
  • QD
  • QF
  • QG
  • QH
  • QJ

Apple store staff will be replacing batteries with spare parts where available, but otherwise will be sending out affected iPhones for a whole unit replacement. Regular wear and tear is expected, so as long as your device is in working order you should be eligible for a battery swap or replacement device if you fall in the serial number range above. Apple store staff will, however, only offer the repair to those that specifically report unexpected shutdown issues. 

Apple notes that the program will cover “affected iPhone 6s batteries for 3 years after the first retail sale of the unit.” You can also request a refund if you’ve already paid for a battery repair or replacement on an eligible device.
