AppleCare+ protection for iPhone, iPad and Apple Watch has refreshed its terms to cover batteries that retain less than 80 percent of their original capacity within the extended warranty period. The new rules apply to Apple Watch Sport, Watch and Edition models, as discovered by MacRumors.
Previously, the extended warranty used to cover Apple Watch batteries that retained less than 50 percent of their original capacity. Apple officially guarantees the Apple Watch battery will retain up to 80 percent of its original capacity at 1,000 complete charge cycles. Assuming an average of one full charge cycle per day, the specification gives the device's battery a lifespan of about two-and-a-half to three years.
