Refurbished models available:

Apple says all refurbished iPhone models are thoroughly inspected, tested, cleaned, and repackaged with a new white box and all manuals and accessories. Apple also installs a new battery and replaces the outer shell, making it nearly impossible to distinguish between a refurbished and brand new iPhone.

Any refurbished iPhone model comes with Apple's standard one-year warranty effective on the date the device is delivered, which can be extended with AppleCare+ at a cost of $199 for the iPhone XS and iPhone XS Max.

Apple is not offering refurbished iPhone XR models at this time.
