Returns and warranty details

Returns

  • Send it back like new

    Return it in its original condition with all included parts, accessories and packaging.

  • How you get your money back

    Card refunds go to your bank within five business days after Apple receives the item. Returns may be inspected; approved refunds or exchanges are issued within 10 business days. Cash returns over $750 are paid by check within 10 business days.

Warranty

Covered

  • Defects in materials and workmanship

    Apple Watch is covered against defects in materials and workmanship for one year from the date of original retail purchase, under a separate Apple Watch warranty document.

  • Battery covered only for defects

    The standard warranty covers a battery only if it fails from a defect. The 80 percent rule belongs to AppleCare, not to the free warranty: AppleCare plans cover batteries that keep less than 80% of their original capacity.

Not covered

  • Water damage

    For iPhone and Apple Vision Pro the warranty names liquid contact as an excluded cause, and Apple's iPhone water page says liquid damage is not covered under warranty. The Apple Watch warranty's version of the same clause does not list liquid contact; see the Apple Watch overrides.

  • Accidents and misuse

    Damage caused by accident, abuse, misuse, fire, earthquake or other external cause is not covered (iPhone, Vision Pro, Apple Watch). The AirPods warranty excludes damage from abuse, accident, modifications or unauthorized repairs.

  • Scratches and dents

    Cosmetic damage such as scratches, dents and broken plastic on ports is not covered unless it comes from a defect.

  • Normal wear and aging

    Defects caused by normal wear and tear or normal aging are not covered.

  • Repairs by other shops

    Damage from service by anyone who is not Apple or an Apple Authorized Service Provider is not covered.

  • How it gets fixed

    Apple chooses to repair, replace with the same model (or a similar one with your consent), or refund the purchase price. For mail-in service Apple sends prepaid waybills and pays shipping both ways if you follow its packing instructions.

Good to know

  • Activation Lock / Find My

    If the security features are on and cannot be turned off by the person returning it, Apple may refuse the return.

  • Opened software

    Opened software, software downloads and gift cards cannot be returned.
