Did one of your AirPods stop working all of a sudden? Before you assume it’s a hardware problem and contact Apple for a repair or replacement AirPod, follow these simple troubleshooting steps, as they can often quickly resolve the issue.
1. Check Your AirPods Battery
It’s possible that one of your AirPods stopped working because it ran out of battery. Each AirPod has its own battery charge, and when it gets drained, that particular AirPod will stop functioning. You’ll have to check the battery level of each AirPod to see if that’s the problem.
Put both AirPods back into the charging case and let them charge for at least 30–60 seconds or up to a few minutes. Then, open the case and hold it near your iPhone to see the battery pop-up. Or, with the case open, use the Settings app to view the AirPods’ battery levels.
