That is a lot, but I wonder if GP’s only decreased by 1% because their phone wasn’t close by. AirPods and their iPhones probably keep pinging each other to maintain the Bluetooth connection, which must have an effect on the battery.
Only when you pull them out of the case. Otherwise they just stay asleep. When I replaced my Powerbeats Pro (same fundamental tech as any AirPods) with AirPods Pro, I went about a year or so without touching the Powerbeats Pro and they just sat in one spot not too far from anything they could connect to since I never unpaired them from anything. I pulled them out a year later, and the Beats themselves were still fully charged and I think the case was still about 70%. Couldn’t tell you what I had left the case at though.
