I followed the advice from ray or about taking my APM off “find my”. I was having similar problems especially the decline in standby but also loosing some 30 Percent per 2-3 hours of viewing both not what I was expecting. Well now with the find my disabled I watched for nearly 3 hours and was down only 3 percent for that time. I am now expecting that 10-15 percent in 24 hour drop will also go away it appears that the APM uses too much power when “find my” is enabled at least upon this limited experiment based on what raynor said.
Of course I also upgraded the firmware so maybe that helped as well but we shall see
I also found info on what happens when “Find My” is turned off here:

Overnight battery drain solution - turn off FindMy
I haven’t seen this posted before, so I thought I’d share:
As many others have reported, the AirPods Max loses some battery overnight before going to deep sleep, even while in the smart case. I’ve seen people report up to 12%. Personally, I see around 8-9%.
This is caused by the FindMy feature. I tried turning it off and now I see around 1% overnight drain! So if you don’t need the FindMy feature, try turning it off.
You find it under Settings-Bluetooth-AirPods Max (while it is connected)
Update: It’s also worth noting that even if you turn off the feature, you’ll still be able to track where you last used the headphones. As far as I can tell, turning it off just disables tracking while in the case (and not plugged in).
Update 2: Ok, so after some testing and reading the replies here, it seems that it is slightly inconsistent. From my own testing, the battery drain each night has been 0-1%, with the exception of the first time I tried it and once a couple of nights ago. So to recap:
- Turn off FindMy at Settings-Bluetooth-AirPods Max (while it is connected)
- Make sure the AirPods are in the smart case (this is important!)
- If after a few nights it is still having "normal" battery drain, try a reboot or even a factory reset (https://support.apple.com/en-us/HT211904) Then turn off FindMy again if it is on again.”
