In order to preserve the battery life of the AirPods wireless earbuds as long as possible, Apple slows down the charging speed significantly once the charge reaches 80 percent.
This is done through the automatic activation of the feature called Battery charging optimization.
However, you can exceed this percentage to reach the maximum by deactivating the feature. Once you make sure your AirPods are fully charged, you can activate them again.
Fully charge your AirPods
- Connect the headphones by removing them from the charging case and placing them in your ears to automatically connect to your device.
- On your iPhone or iPad, open the Settings app and then select the Bluetooth option.
- Press the i button next to the name of the speakers connected to your device.
- Scroll down and toggle the button next to the Optimized battery charging option to the off position.
- Confirm the command in the popup that appears.
- You can select to turn the feature off or disable it permanently.
Once the speakers are 100 percent charged, you can follow the same steps above to turn the feature back on or wait for it to turn on automatically.

Reasons for slow charging speed of Apple wireless headphones
Battery charging optimization extends the battery life of the AirPods and AirPods Pro wireless earbuds.
This is done by extending the battery life which allows you to use the headphones for as long as possible when you are away from the charger.
AirPods Pro use lithium-ion battery technology like any other electronic device. This means that the efficiency of the battery life decreases over time. This feature extends the life of these batteries for as long as possible.
Note that this feature requires your phone or tablet to be running iOS 14.2, iPadOS 14.2 or later.
