I use them for about 4 hours a day, about 1 conference call every other day.
I know they need new batteries because from full charge, they won't get through a single hour-long conference call anymore without blasting the low battery warning.
I used to be able to eek out about 2 1-hour conference calls before getting the warning.
Surprised you can wear those things that long. I've found my iPhone or MBP speaker have better noise reduction than the AirPods, and they're not comfortable to have in for multiple hours at a time.
When I need to do this - I only wear one AirPods, and keep the other charged in the case. Mic quality seems improved also with only 1 AirPods.
