My iPhone is not eligible for warranty service. What are my service options?

There are two service options for an iPhone that is not eligible for warranty service.

1. Battery Replacement Service

   If your iPhone requires service due to the battery's diminished ability to hold an electrical charge and it is not covered under Apple's warranty or statutory consumer rights, please contact your carrier.

2. Out-of-Warranty Service

   Please contact your carrier for out-of-warranty service options.
