Apple's Official IPhone Free Battery Replacement Conditions Standard

What are the requirements for the free battery replacement of iPhone?

  Recently, Apple has updated its new battery replacement service on its official website. Only two conditions are met to achieve free battery replacement after Apple's sales.

  First of all, your iPhone must be in the warranty period. The warranty period is calculated from the activation date of your iPhone. You can check the specific activation warranty date through the serial number on the official website. Of course, your iPhone must be the National Bank version.

   The second is that the battery efficiency of your iPhone is less than 80%. This can be seen in the settings-battery option to see the corresponding battery efficiency (it will only be displayed after iOS 11.3).

    As long as the above two conditions are met, the iphone battery efficiency of your iPhone will be reduced to less than 80% within one year, and the replaced battery can be replaced for free. Of course, if you buy AppleCare+, you can also enjoy it.
