One possible reason why one of your AirPods is not working after a reset is that the battery in that particular AirPod is completely drained. AirPods have separate batteries in each earbud, and they can drain at different rates depending on factors such as usage and the age of the AirPods.
When you perform a reset on your AirPods, it essentially restarts the connection between the AirPods and your device. This can sometimes help resolve connectivity issues, but it does not directly address battery problems. If one of your AirPods has a dead battery, it will still not function properly even after a reset.
To check the battery level of your AirPods, you can either use the battery widget on your connected device or open the AirPods case near your iPhone and check the pop-up window. If you see that one AirPod has a significantly lower battery level than the other, it is likely that the low battery is causing the issue.
To resolve this, you can simply charge your AirPods. Place both AirPods back into the charging case and make sure the case itself has enough battery power. If the case is also low on battery, you may need to charge it using a Lightning cable.
Once your AirPods are placed in the case and charging, you should see an LED light on the front of the case indicating that they are charging. Leave them in the case for a while, and the low battery AirPod should gradually start charging. After some time, you can remove them from the case and check if they are working properly.
It is worth noting that if one of your AirPods consistently drains its battery faster than the other, it could be a sign of a hardware issue or a defective battery. If charging the AirPod does not resolve the problem and the issue persists, you may want to consider contacting Apple Support or visiting an Apple Store for further assistance.
If one of your AirPods is not working after a reset, the most likely explanation is that the battery in that AirPod is dead. Charging the AirPod should resolve the issue, but if it continues to have battery problems, consider contacting Apple Support for further assistance.
