Optimised battery charging function for AirPods Gen 2

I believe this feature is only available on the AirPod Pros.

Not sure what you mean here. Are you seeing the "Optimize Battery Charging" in the bluetooth settings for the AirPod 2? I see no option for both AirPods 1 and 2, only for the Pro's.

Look under "Optimized Battery Charging on AirPods Pro" here: https://support.apple.com/en-ca/HT207012

Then why every time I look it up it’s available for every set of AirPods no matter what the model. FYI I have AirPods 2

when I look up what models get it on safari it says that all get it but I don’t get an option to turn it of or on in the Bluetooth settings

Read the page it’s pros only thanks for the help
