Better keep it safe: Apple HomePod repair costs $279
If you live in the US, you will have to give Apple $279 if you want your HomePod to live a second life. That's in case the smart speaker is severely damaged and the damage is not due to a manufacturing problem, which the one year warranty covers. To give you a brief comparison, a new HomePod will cost you $349, meaning that the repair fee is around 80% of the retail price.
To be on the safe side, you have the option to purchase an Apple Care+ plan for the HomePod within 60 days of your initial purchase. Apple's warranty extension program costs $39 and drops the service price significantly, giving you up to two incidents of accidental damage coverage, each subject to a $39 fee.
