Troubleshooting AirPods Power Draining:

A. Start with a Reset:

Rather than factory resetting these, try just resetting these...

Go Here: Reset your AirPods - Apple Support

B. A Few Links to Visit:

• Start Here: Charge your AirPods with Charging Case and Learn about Battery Life - Apple Support

• If your AirPods Con’t Charge - Apple Support

• How to Clean your AirPods and EarPods - Apple Support

C. Try the Following Tasks:

• Hold Down the Button on the case for about 15 seconds.

• Use an Apple Brand Cable - not a third party one - cool though it may look, a fabric, third-part cable would likely tear - (Apple cable's are plastic and are intended for Apple)

• Remove the AirPod from the Case, then place it back in the charger. Perhaps it need to resync with he charger.

Thank you for the followup reply.

Then that would indicate this is a glitch.

Excellent job troubleshooting this!

Report this to Apple...

Do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple

The retitling is nothing on you or me.

So, as recommended in my first reply: Connect this to another device, seeing if it is different than 40%. A bit odd, indeed, but it may have been a glitch in th iPhone, which was corrected with he update on it.

AirPod Percentage After an Update:

Single-Out this Device for Discrepancy:

Maybe the percentage declined upon the update. So, what happens when you apr these to another device of yours (one that shows you the percentage). If there is discrepancy, then there is a bug between the devices. So, update ether AirPods. The only way for AirPods to be updated is when they are conceded to a device that itself is connected to the Internet. ApirPods cannot be updated on their own, as they are not assigned their own IP address.

My original post was re-titled by the moderator. This is incorrect. My original post read:
