Even Apple Watch batteries can swell.
Responding to user complaints about the issue, Apple has extended its warranty coverage for the first-gen Apple Watch’s expanded/swollen battery issues to three years. This covers customers for services an additional two years beyond the complimentary 1-year Limited Warranty Period.
The issue with swollen and expanded batteries on first-gen Apple Watch models has been documented online by users experiencing the problem— here on Apple support forums, for example, and on Reddit— but appears to not be widespread or something that has made mainstream media headlines.
The change comes as the 1st gen Apple Watch passes the two year mark after having been introduced April 24, 2015.
