Airpods Pro 3 battery drain on the case is too high

Then you had the special AirPod Pro 2s.

This is what Apple says you should have expected from them:

AirPods Pro 

• Up to 6 hours of listening time with a single charge (up to 5.5 hours with Spatial Audio and Head Tracking enabled)4
• Up to 4.5 hours of talk time with a single charge5

AirPods Pro with MagSafe Charging Case 

• Up to 30 hours of listening time6
• Up to 24 hours of talk time7

5 minutes in the case provides around 1 hour of listening time8 or around 1 hour of talk time

Mind you, I don't see what that has to do with your original statement. You make an observation about the fact that if your AirPods charged up from the case, the charge on the case dropped. You said nothing about time.

I got a very version (ordered the first day of release). They have been an unmitigated disaster. Screeching noises, feedback, underwater sounds. Essentially unusable. Case is now stating to 'replace the battery soon'. Assuming this is a software issue.

Curiously, the few times i've actually been able to use them for a full day, battery life in the actual pods was fantastic. Have had every version of pros before this and they were all amazing. Guessing we just got duds and/or they launched earlier than they should have.

It is from the day they were shipped.

Great troubleshooting! I’m glad it’s resolved.

My AirPods Pro 3 case was at 90% on my MagSafe charger last night. I get and find it at 60…

The case was once updated to 8A857 but downgraded to 8A853 last night??

Here the buds were at 60% and after charging to 100% the case dropped from 100% to 60%..

Oh I thought they charged wireless by magic through the air.

On this rate of discharge I can have a max of 16 hours or recharge every day. My AirPods 2 needed to reload every 3 days.

How the heck do you do this?

The AirPod's firmware is listed in the iPhone's Settings ➙ Bluetooth ➙ AirPod settings pane:

How did you realize this was happening? Did it start happening after you experienced something or has it been like this since you bought it? I'm having the same problem. Do you have any suggestions?

When the case is used to charge the AirPods, the case loses charge. You'll need to charge the case.

Check your case firmware. If it is 8A353 you need to update, to keep the case charged together with your iPhone for 30 min. After update to 8A357 my similar issue ended.
